## version tag patching
|
||||
|
||||
here's a little guide on how to patch patterns in the database to prevent breaking old patterns due to breaking changes in newer versions.
|
||||
|
||||
the general tactic is to use `// @version x.y` to tag a pattern with a specific strudel version. when a pattern is evaluated, this metadata will de-activate any breaking changes that came after the specified version.
|
||||
for example, in version 1.1, the default value for `fanchor` was changed from `0.5` to `0`.
|
||||
if play a pattern that was made before that change, sounds that use filter evenlopes can sound very different, so by adding `// @version 1.0` will make it sound like it used to.
|
||||
before releasing a new version with breaking changes, we can edit all patterns in the database, inserting the version tag they were created under:
|
||||
|
||||
as an example, to release version 1.2, do the following:
|
||||
|
||||
1. get date range
|
||||
|
||||
```sh
|
||||
# get date of last version:
|
||||
git log -1 --format=%aI @strudel/core@1.1.0
|
||||
# 2024-05-31T23:07:26+02:00
|
||||
|
||||
# get date of current version:
|
||||
git log -1 --format=%aI @strudel/core@1.2.0
|
||||
# 2025-05-01T12:39:24+02:00
|
||||
# might also use todays timestamp if version is not yet released
|
||||
```
|
||||
|
||||
now we know, all patterns between these 2 dates have to receive a version tag (unless they already have one).
|
||||
|
||||
2. get patterns in question
|
||||
|
||||
```sql
|
||||
SELECT *
|
||||
FROM code_v1
|
||||
WHERE code NOT LIKE '%@version%'
|
||||
AND created_at > '2024-05-31T23:07:26+02:00'
|
||||
AND created_at < '2025-05-01T12:39:24+02:00'
|
||||
ORDER BY created_at ASC;
|
||||
```
|
||||
|
||||
this gives us all unversioned patterns that were saved between 1.1.0 and 1.2.0. in this case, it's 9373 patterns!
|
||||
|
||||
3. insert version tags
|
||||
|
||||
we are now ready to insert the version tag to these patterns.
|
||||
before updating thousands of patterns, it's probably a good idea to test if a single one gets udpated:
|
||||
|
||||
```sql
|
||||
UPDATE code_v1
|
||||
SET code = code || E'\n// @version 1.1'
|
||||
WHERE hash = 'Ns2sMB40yIw4';
|
||||
```
|
||||
|
||||
after [verifying](https://strudel.cc/?Ns2sMB40yIw4) that the version tag has been added, let's insert it everywhere:
|
||||
|
||||
```sql
|
||||
UPDATE code_v1
|
||||
SET code = code || E'\n// @version 1.1'
|
||||
WHERE code NOT LIKE '%@version%'
|
||||
AND created_at > '2024-05-31T23:07:26+02:00'
|
||||
AND created_at < '2025-05-01T12:39:24+02:00'
|
||||
```
|
||||
|
||||
4. verify
|
||||
|
||||
we can verify that the edits worked by querying all patterns that contain the new version tag:
|
||||
|
||||
```sql
|
||||
SELECT *
|
||||
FROM code_v1
|
||||
WHERE code LIKE '%@version 1.1%'
|
||||
AND created_at > '2024-05-31T23:07:26+02:00'
|
||||
AND created_at < '2025-05-01T12:39:24+02:00'
|
||||
ORDER BY created_at ASC;
|
||||
```
|
||||

||||

This paper introduces Strudel, which brings the TidalCycles approach to live coding algorithmic patterns to
|
||||
native JavaScript and the web. We begin by giving a little background of the first year of development, before
|
||||
sharing some detail about its implementation and examples of use. We go on to outline the wide range of
|
||||
synthesis and other outputs available in Strudel, including WebAudio, MIDI, OSC (for SuperDirt), WebSerial and
|
||||
CSound, and introduce Strudel’s REPL live editor, including its built-in visualisations. We then compare Strudel
|
||||
with Tidal, the trade-offs involved between JavaScript and Haskell, and the unique capabilities offered by
|
||||
Strudel for aligning patterns.

|
||||
<p>
|
||||
In the following paper, we introduce <em>Strudel</em>, an alternative implementation of the TidalCycles (or
|
||||
‘Tidal’ for short) live coding system, using the JavaScript programming language. Strudel is an attempt to make
|
||||
live coding more accessible, by creating a system that runs entirely in the browser, while opening Tidal’s
|
||||
approach to algorithmic patterns
|
||||
<span class="citation" data-cites="mcleanAlgorithmicPattern2020a">(Mclean 2020)</span> up to modern audio/visual
|
||||
web technologies. The Strudel REPL is a live code editor dedicated to manipulating patterns while they play, with
|
||||
builtin visual feedback. While Strudel is written in JavaScript, the API is optimized for simplicity and
|
||||
readability by applying code transformations on the syntax tree level, allowing language operations that would
|
||||
otherwise be impossible. The application supports multiple ways to output sound, including Tone.js, Web Audio
|
||||
Nodes, OSC (Open Sound Control) messages, Web Serial, Web MIDI and Csound. The project is split into multiple
|
||||
packages, allowing granular reuse in other applications. Apart from TidalCycles, Strudel draws inspiration from
|
||||
many prior existing projects like TidalVortex

The first tentative commit to the Strudel project was on 22nd January 2022 by Alex McLean, with the core
|
||||
representation implemented over the following few days. Although this was his first attempt at a JavaScript-based
|
||||
application, by 27th January, Alex had managed to upload the initial version to the ‘npm’ javascript package
|
||||
database, sharing with the wider community for comment. By 4th February, Felix Roos had discovered Strudel and
|
||||
contributed a ‘REPL’ user interface to it, and then contributed a scheduler the next day, so that Strudel could
|
||||
already make sound. At this point, Alex and Felix shared ownership to the repository, and the project has since
|
||||
proved to be a productive confluence of Felix’s own work into music representation and visualisation, with Alex’s
|
||||
experience with making Tidal. Felix has since become the primary contributor to Strudel, with Alex continuing to
|
||||
jump between developing both Strudel and Tidal. Aspects of Strudel’s development have therefore fed back into
|
||||
TidalCycles, and both systems have maintained a shared conceptual underpinning. We plan to continue working
|
||||
towards feature parity between these systems, although within the syntactical trade-offs and library ecosystems of
|
||||
JavaScript and Haskell, some divergence is inevitable and healthy.
|
||||
</p>
|
||||
<p>
|
||||
Over the first year of its life, Strudel is now a fully-fledged live coding environment, porting Tidal’s core
|
||||
represention of patterns, pattern transformations, and mininotation for polymetric sequences, combined with a
|
||||
wealth of features for synthesising and visualising those patterns.
|
||||

<h1 data-number="2" id="from-tidal-to-strudel-and-back">
|
||||
<span class="header-section-number">2</span> From Tidal to Strudel and back
|
||||
</h1>
|
||||
<p>
|
||||
As mentioned above, the original Tidal is implemented as a domain specific language (DSL) embedded in the Haskell
|
||||
pure functional programming language, and takes advantage of Haskell’s terse syntax and advanced, ‘strong’ type
|
||||
system. JavaScript on the other hand, is a multi-paradigm programming language, with a dynamic type system.
|
||||
Because Tidal leans heavily on many of Haskell’s more unique features, it was not always clear that it could
|
||||
meaningfully be ported to a multi-paradigm scripting language. However, this possibility was already demonstrated
|
||||
with an earlier port to Python [TidalVortex;
|
||||
<span class="citation" data-cites="mcleanTidalVortexZero2022">McLean et al. (2022)</span>], and we have now
|
||||
successfully implemented Tidal’s pure functional representation of patterns in Strudel, including partial
|
||||
application, currying, and the functor, applicative and monadic structures that underlie Tidal’s expressive
|
||||
pattern transformations. The result is a terse and highly composable system, where everything is either a pattern,
|
||||
or a function for combining and manipulating patterns, offering a rich creative ground for exploration.
|
||||
</p>
|
||||
<p>
|
||||
This development process has been far from a one-way port, however. The process of porting Tidal’s concepts has
|
||||
also opened up new possibilities, some just from revisiting every design decision, and some from the particular
|
||||
affordances and constraints offered by JavaScript. This has lead to new features (and indeed bugfixes) that have
|
||||
found their way back to Tidal where appropriate, and ongoing work that we will return to in the conclusion of this
|
||||
paper.

<span class="header-section-number">3</span> Representing Patterns
|
||||
</h1>
|
||||
<p>
|
||||
Patterns are the essence of Tidal. Its patterns are abstract entities that represent flows of time as functions,
|
||||
adapting a technique called pure functional reactive programming. Taking a time span as its input, a Pattern can
|
||||
output a set of events that happen within that time span. It depends on the structure of the Pattern how the
|
||||
events are located in time. From now on, this process of generating events from a time span will be called
|
||||
<strong>querying</strong>. Example:
|
||||
</p>
|
||||
<div class="sourceCode" id="cb1">
|
||||
<pre
|
||||
class="sourceCode js"
|
||||
><code class="sourceCode javascript"><span id="cb1-1"><a href="#cb1-1" aria-hidden="true" tabindex="-1"></a><span class="kw">const</span> pattern <span class="op">=</span> <span class="fu">sequence</span>(c3<span class="op">,</span> [e3<span class="op">,</span> g3])</span>
|
||||
<span id="cb1-2"><a href="#cb1-2" aria-hidden="true" tabindex="-1"></a><span class="kw">const</span> events <span class="op">=</span> pattern<span class="op">.</span><span class="fu">queryArc</span>(<span class="dv">0</span><span class="op">,</span> <span class="dv">1</span>)</span>
|
||||
<span id="cb1-3"><a href="#cb1-3" aria-hidden="true" tabindex="-1"></a><span class="bu">console</span><span class="op">.</span><span class="fu">log</span>(events<span class="op">.</span><span class="fu">map</span>(e <span class="kw">=></span> e<span class="op">.</span><span class="fu">show</span>()))</span></code></pre>
|
||||
</div>
|
||||
<p>
|
||||
In this example, we create a pattern using the <code>sequence</code> function and <strong>query</strong> it for
|
||||
the time span from <code>0</code> to <code>1</code>. Those numbers represent units of time called
|
||||
<strong>cycles</strong>. The length of one cycle depends on the tempo, which defaults to one cycle per second. The
|
||||
resulting events are:
|
||||
</p>
|
||||
<div class="sourceCode" id="cb2">
|
||||
<pre
|
||||
class="sourceCode js"
|
||||

<span id="cb2-2"><a href="#cb2-2" aria-hidden="true" tabindex="-1"></a>{ <span class="dt">value</span><span class="op">:</span> <span class="st">'e3'</span><span class="op">,</span> <span class="dt">begin</span><span class="op">:</span> <span class="dv">1</span><span class="op">/</span><span class="dv">2</span><span class="op">,</span> <span class="dt">end</span><span class="op">:</span> <span class="dv">3</span><span class="op">/</span><span class="dv">4</span> }<span class="op">,</span></span>
|
||||
<span id="cb2-3"><a href="#cb2-3" aria-hidden="true" tabindex="-1"></a>{ <span class="dt">value</span><span class="op">:</span> <span class="st">'g3'</span><span class="op">,</span> <span class="dt">begin</span><span class="op">:</span> <span class="dv">3</span><span class="op">/</span><span class="dv">4</span><span class="op">,</span> <span class="dt">end</span><span class="op">:</span> <span class="dv">1</span> }]</span></code></pre>
|
||||
</div>
|
||||
<p>
|
||||
Each event has a value, a begin time and an end time, where time is represented as a fraction. In the above case,
|
||||
the events are placed in sequential order, where c3 takes the first half, and e3 and g3 together take the second
|
||||
half. This temporal placement is the result of the <code>sequence</code> function, which divides its arguments
|
||||
equally over one cycle. If an argument is an array, the same rule applies to that part of the cycle. In the
|
||||
example, e3 and g3 are divided equally over the second half of the whole cycle.
|
||||
</p>
|
||||
<p>
|
||||
The above examples do not represent how Strudel is used in practice. In the live coding editor, the user only has
|
||||
to type in the pattern itself, the querying will be handled by the scheduler. The scheduler will repeatedly query
|
||||
the pattern for events, which are then scheduled as sound synthesis or other event triggers. Also, the above event
|
||||
data structure has been simplified for readability.

|
||||
<p>
|
||||
In practice, the end-user live coder will not deal with constructing patterns directly, but will rather build
|
||||
patterns using Strudel’s extensive combinator library to create, combine and transform patterns.
|
||||
</p>
|
||||
<p>
|
||||
The live coder will rarely use the <code>sequence</code> function as seen above, as sequencing is implicit in many
|
||||
functions. For example in the following, the <code>note</code> function constructs a pattern of notes, sequencing
|
||||
its arguments in the same manner as the previous example.

Perhaps more often, they will use the mini-notation for even terser notation of rhythmic sequences: [^This last
|
||||
example is also valid Tidal code, albeit the parenthesis is not required in its Haskell syntax in this case. Tidal
|
||||
does not support passing sequences as lists directly to the <code>note</code> function, however.].

Such sequences are often treated only a starting point for manipulation, where they then undergo pattern
|
||||
transformations such as repetition, symmetry, interference/combination or randomisation, potentially at multiple
|
||||
timescales. Because Strudel patterns are represented as pure functions of time rather than as data structures,
|
||||
very long and complex generative results can be represented and manipulated without having to store the resulting
|
||||
sequences in memory.

The pattern starts with a rhythm of numbers in mini notation, which are later interpreted inside the scale of D

minor. The first line could also be expressed without mini notation:

These numbers then undergo various pattern transformations. Here is a short description of all the functions used:

</p>
|

<ul>
|
||||
<li><code>cat</code>: play elements sequentially, where each lasts one cycle</li>
|
||||
<li><code>brackets</code>: elements inside brackets are divided equally over the time of their parent</li>
|
||||
<li>
|
||||
<code>.euclid(p, s, o)</code>: place p pulses evenly over s steps, with offset o
|
||||
<span class="citation" data-cites="toussaintEuclideanAlgorithmGenerates2005">(Toussaint 2005)</span>
|
||||
</li>
|
||||
<li>
|
||||
<code>.off(n, f)</code>: layers a pattern on top of itself, with the new layer offset by n cycles, and with
|
||||
function f applied
|
||||
</li>
|
||||
<li><code>.legato(n)</code>: multiply the duration of all events in a pattern by a factor of n</li>
|
||||
<li>
|
||||
<code>.echo(t, n, v)</code>: copy each event t times, with n cycles in between each copy, decreasing velocity by
|
||||
v
|
||||
</li>
|
||||
<li><code>.note()</code>: interpretes values as notes</li>
|
||||
<li><code>.s(name)</code>: play back each event with the given sound</li>
|
||||
<li><code>.delay(wet)</code>: add delay</li>
|
||||
<li><code>.delaytime(t)</code>: set delay time</li>
|
||||
</ul>
|
||||
<p>Much of the above will be familiar to Tidal users.</p>
|
||||
<!-- This example shows some of Strudel's unique support for chords and transposition familiar to students of Western music theory. This differs a little from Tidal's approach and thanks to the integration of the javascript library XXX (*TODO* ? or is this all your work Felix?), Strudel's support for tonal transformations such as voice leading is perhaps respects more advanced than Tidal. -->

<h1 data-number="6" id="ways-to-make-sound-and-other-events">
|
||||
<span class="header-section-number">6</span> Ways to make Sound (and other events)
|
||||
</h1>
|
||||
<p>To generate sound, Strudel supports bindings for different outputs:</p>
|
||||
<ul>
|
||||
<li>Tone.js (deprecated)</li>
|
||||
<li>Web Audio API</li>
|
||||
<li>WebDirt, a js recreation of Tidal’s <em>Dirt</em> sample engine (deprecated)</li>
|
||||
<li>OSC via osc-js, compatible with superdirt</li>
|
||||
<li>Csound via the Csound WebAssembly build</li>
|
||||
<li>MIDI via WebMIDI</li>
|
||||
<li>Serial via WebSerial</li>
|
||||
</ul>
|
||||
<p>
|
||||
At first, we used Tone.js as sound output, but it proved to be limited for the use case of Strudel, where each
|
||||
individual event could potentially have a completely different audio graph. While the Web Audio API takes a
|
||||
<em>fire-and-forget</em> approach, creating a lot of Tone.js instruments and effects causes performance issues
|
||||
quickly. For that reason, we chose to search for alternatives.
|
||||
</p>
|
||||
<p>
|
||||
Strudel’s new default output uses the Web Audio API to create a new audio graph for each event. It currently
|
||||
supports basic oscillators, sample playback, various effects and an experimental support for soundfonts.
|
||||
</p>
|
||||
<p>
|
||||
WebDirt <span class="citation" data-cites="ogbornDktr0WebDirt2022">(Ogborn [2016] 2022)</span> was created as part
|
||||
of the Estuary Live Coding System
|
||||
<span class="citation" data-cites="ogbornEstuaryBrowserbasedCollaborative2017">(Ogborn et al. 2017)</span>, and
|
||||
proved to be a solid choice for handling samples in Strudel as well. We are however focused on working more
|
||||
directly with the Web Audio API to be able to integrate new features more tightly.
|
||||
</p>
|
||||
<p>
|
||||
Using the OSC protocol via Strudel’s provided Node.js-based OSC proxy server, it is possible to send network
|
||||
messages to trigger events. This is mainly used to render sound using SuperDirt
|
||||
<span class="citation" data-cites="SuperDirt2022">(<em>SuperDirt</em> [2015] 2022)</span>, which is the
|
||||
well-developed Supercollider-based synthesis framework that Tidal live coders generally use as standard.
|
||||
</p>
|
||||
<p>
|
||||
Recently, the experimental integration of Csound proved to bring a new dimension of sound design capabilities to
|
||||
Strudel. Thanks to the WebAssembly distribution of this classic system
|
||||
<span class="citation" data-cites="CsoundWebAssembly">(Yi, Lazzarini, and Costello 2018)</span>, Csound
|
||||
‘orchestra’ synthesisers can be embedded in and then patterned with Strudel code.
|
||||
</p>
|
||||
<p>
|
||||
MIDI output can also be used to send MIDI messages to either external instruments or to other programs on the same
|
||||
device. Unlike OSC, Strudel is able to send MIDI directly without requiring additional proxy software, but only
|
||||
from web browsers that support it (at the time of writing, this means Chromium-based browsers).
|
||||
</p>
|
||||
<p>
|
||||
Finally, Strudel supports Serial output, for example to trigger events via microcontrollers. This has already been
|
||||
explored for robot choreography by Kate Sicchio and Alex McLean, via a performance presented at the International
|
||||
Conference on Live Interfaces 2022.

<h1 data-number="7" id="the-strudel-repl"><span class="header-section-number">7</span> The Strudel REPL</h1>
|
||||
<p>
|
||||
While Strudel can be used as a library in any JavaScript codebase, its main, reference user interface is the
|
||||
Strudel REPL[^REPL stands for read, evaluate, print/play, loop. It is friendly jargon for an interactive
|
||||
programming interface from computing heritage, usually for a commandline interface but also applied to live coding
|
||||
editors.], which is a browser-based live coding environment. This live code editor is dedicated to manipulating
|
||||
Strudel patterns while they play. The REPL features built-in visual feedback, which highlights which elements in
|
||||
the patterned (mini-notation) sequences are influencing the event that is currently being played. This feedback is
|
||||
designed to support both learning and live use of Strudel.
|
||||
</p>
|
||||
<p>
|
||||
Besides a UI for playback control and meta information, the main part of the REPL interface is the code editor
|
||||
powered by CodeMirror. In it, the user can edit and evaluate pattern code live, using one of the available
|
||||
synthesis outputs to create music and/or sound art. The control flow of the REPL follows 3 basic steps:
|
||||
</p>
|
||||
<ol type="1">
|
||||
<li>
|
||||
The user writes and updates code. Each update transpiles and evaluates it to create a
|
||||
<code>Pattern</code> instance
|
||||
</li>
|
||||
<li>
|
||||
While the REPL is running, the <code>Scheduler</code> queries the active <code>Pattern</code> by a regular
|
||||
interval, generating <code>Events</code> (also known as <code>Haps</code> in Strudel) for the next time span.
|
||||
</li>
|
||||
<li>
|
||||
For each scheduling tick, all generated <code>Events</code> are triggered by calling their
|
||||
<code>onTrigger</code> method, which is set by the output.
|
||||
</li>
|
||||
</ol>

<h2 data-number="7.1" id="user-code"><span class="header-section-number">7.1</span> User Code</h2>
|
||||
<p>To create a <code>Pattern</code> from the user code, two steps are needed:</p>
|
||||
<ol type="1">
|
||||
<li>Transpile the JS input code to make it functional</li>
|
||||
<li>Evaluate the transpiled code</li>
|

</ol>

<h3 data-number="7.1.1" id="transpilation-evaluation">
|
||||
<span class="header-section-number">7.1.1</span> Transpilation & Evaluation
|
||||
</h3>
|
||||
<p>
|
||||
In the JavaScript world, using transpilation is a common practise to be able to use language features that are not
|
||||
supported by the base language. Tools like <code>babel</code> will transpile code that contains unsupported
|
||||
language features into a version of the code without those features.
|
||||
</p>
|
||||
<p>
|
||||
In the same tradition, Strudel can add a transpilation step to simplify the user code in the context of live
|
||||
coding. For example, the Strudel REPL lets the user create mini notation patterns using just double quoted
|
||||
strings, while single quoted strings remain what they are:
|
||||
</p>

||||

|
||||
</div>
|
||||
<p>is transpiled to:</p>
|
||||
<div class="sourceCode" id="cb8">
|
||||
<pre
|
||||
class="sourceCode js"
|
||||
><code class="sourceCode javascript"><span id="cb8-1"><a href="#cb8-1" aria-hidden="true" tabindex="-1"></a><span class="fu">mini</span>(<span class="st">"c3 [e3 g3]*2"</span>)<span class="op">.</span><span class="fu">withMiniLocation</span>([<span class="dv">1</span><span class="op">,</span><span class="dv">0</span><span class="op">,</span><span class="dv">0</span>]<span class="op">,</span>[<span class="dv">1</span><span class="op">,</span><span class="dv">14</span><span class="op">,</span><span class="dv">14</span>])</span></code></pre>
|
||||
</div>
|
||||
<p>
|
||||
Here, the string is wrapped in <code>mini</code>, which will create a pattern from a mini notation string.
|
||||
Additionally, the <code>withMiniLocation</code> method passes the original source code location of the string to
|
||||
the pattern, which enables highlighting active events.
|
||||
</p>
|
||||
<p>
|
||||
Other convenient features like pseudo variables, operator overloading and top level await are possible with
|
||||
transpilation.
|
||||
</p>
|
||||
<p>After the transpilation, the code is ready to be evaluated into a <code>Pattern</code>.</p>
|
||||
<p>
|
||||
Behind the scenes, the user code string is parsed with <code>acorn</code>, turning it into an Abstract Syntax Tree
|
||||
(AST). The AST allows changing the structure of the code before generating the transpiled version using
|
||||
<code>escodegen</code>.
|
||||
</p>
|
||||
<h3 data-number="7.1.2" id="mini-notation"><span class="header-section-number">7.1.2</span> Mini Notation</h3>
|
||||
<p>
|
||||
While the transpilation allows JavaScript to express Patterns in a less verbose way, it is still preferable to use
|
||||
the Mini Notation as a more compact way to express rhythm. Strudel aims to provide the same Mini Notation features
|
||||
and syntax as used in Tidal.
|
||||
</p>
|
||||
<p>
|
||||
The Mini Notation parser is implemented using <code>peggy</code>, which allows generating performant parsers for
|
||||
Domain Specific Languages (DSLs) using a concise grammar notation. The generated parser turns the Mini Notation
|
||||
string into an AST which is used to call the respective Strudel functions with the given structure. For example,
|
||||
<code>"c3 [e3 g3]*2"</code> will result in the following calls:

<span class="header-section-number">7.1.3</span> Highlighting Locations
|

</h3>
|
||||
<p>
|
||||
As seen in the examples above, both the JS and the Mini Notation parser add source code locations using
|
||||
<code>withMiniLocation</code> and <code>withLocation</code> methods. While the JS parser adds locations relative
|
||||
to the user code as a whole, the Mini Notation adds locations relative to the position of the mini notation
|
||||
string. The absolute location of elements within Mini Notation can be calculated by simply adding both locations
|
||||
together. This absolute location can be used to highlight active events in real time.

<h2 data-number="7.2" id="scheduling-events"><span class="header-section-number">7.2</span> Scheduling Events</h2>
|

<p>
|

After an instance of <code>Pattern</code> is obtained from the user code, it is used by the scheduler to get
|
||||
queried for events. Once started, the scheduler runs at a fixed interval to query active pattern for events
|
||||
withing the current interval’s time span. A simplified implementation looks like this:

||||
Note that the above code is simplified for illustrative purposes. The actual implementation has to work around
|
||||
imprecise callbacks of <code>setInterval</code>. More about the implementation details can be read in
|
||||
<a href="https://loophole-letters.vercel.app/web-audio-scheduling">this blog post</a>.
|
||||
</p>
|
||||
<p>
|
||||
The fact that <code>Pattern.queryArc</code> is a pure function that maps a time span to a set of events allows us
|
||||
to choose any interval we like without changing the resulting output. It also means that when the pattern is
|
||||
changed from outside, the next scheduling callback will work with the new pattern, keeping its clock running.
|
||||
</p>
|
||||
<p>
|
||||
The latency between the time the pattern is evaluated and the change is heard is between
|
||||
<code>minLatency</code> and <code>interval + minLatency</code>, in our example between 100ms and 600ms. In
|
||||
Strudel, the current query interval is 50ms with a minLatency of 100ms, meaning the latency is between 50ms and
|
||||
150ms.

|

<p>
|
||||
The last step is to trigger each event in the chosen output. This is where the given time and value of each event
|
||||
is used to generate audio or any other form of time based output. The default output of the Strudel REPL is the
|
||||
WebAudio output. To understand what an output does, we first have to understand what control parameters are.

Here, the control parameter functions <code>note</code>, <code>cutoff</code> and <code>s</code> are used, where
|
||||
each controls a different property in the value object. Each control parameter function accepts a primitive value,
|
||||
a list of values to be sequenced into a <code>Pattern</code>, or a <code>Pattern</code>. In the example,
|
||||
<code>note</code> gets a <code>Pattern</code> from a Mini Notation expression (double quoted), while
|
||||
<code>cutoff</code> and <code>s</code> are given a <code>Number</code> and a (single quoted)
|
||||
<code>String</code> respectively.
|

</p>
|
||||
<p>
|
||||
Strudel comes with a large default set of control parameter functions that are based on the ones used by Tidal and
|
||||
SuperDirt, focusing on music and audio terminology. It is however possible to create custom control paramters for
|
||||
any purpose:

<p>

This example creates the custom control parameters <code>x</code> and <code>y</code> which are then used to form a

Now that we know how the value of an event is manipulated using control parameters, we can look at how outputs can
|

use that value to generate anything. The scheduler above was calling the <code>onTrigger</code> function which is
|
||||
used to implement the output. A very simple version of the web audio output could look like this:

The above example will create an <code>OscillatorNode</code> for each event, where the frequency is controlled by
|
||||
the <code>note</code> param. In essence, this is how the WebAudio API output of Strudel works, only with many more
|
||||
parameters to control synths, samples and effects.

|

<h1 data-number="8" id="pattern-alignment-and-combination">
|
||||
<span class="header-section-number">8</span> Pattern alignment and combination
|
||||
</h1>
|
||||
<p>
|
||||
One core aspect of Strudel, inherited from Tidal, is the flexible way that patterns can be combined, irrespective
|
||||
of their structure. Its declarative approach means a live coder does not have to think about the details of
|
||||
<em>how</em> this is done, only <em>what</em> is to be done.
|
||||
</p>
|
||||
<p>
|
||||
As a simple example, consider two number patterns <code>"0 [1 2] 3"</code>, and <code>"10 20"</code>. The first
|
||||
has three contiguous steps of equal lengths, with the second step broken down into two substeps, giving four
|
||||
events in total. There are a very large number of ways in which the structure of these two patterns could be
|
||||
combined, but the default method in both Strudel and Tidal is to line up the cycles of the two patterns, and then
|
||||
take events from the first pattern and match them with those in the second pattern. Therefore, the following two
|
||||
lines are equivalent:
|
||||
</p>
|
||||
<div class="sourceCode" id="cb14">
|
||||
<pre
|
||||
class="sourceCode js"
|
||||
><code class="sourceCode javascript"><span id="cb14-1"><a href="#cb14-1" aria-hidden="true" tabindex="-1"></a><span class="st">"0 [1 2] 3"</span><span class="op">.</span><span class="fu">add</span>(<span class="st">"10 20"</span>)</span>
|
||||
<span id="cb14-2"><a href="#cb14-2" aria-hidden="true" tabindex="-1"></a><span class="st">"10 [11 22] 23"</span></span></code></pre>
|
||||
</div>
|
||||
<p>
|
||||
Where the events only partially overlap, they are treated as fragments of the event in the first pattern. This is
|
||||
a little difficult to conceptualise, but lets start by comparing the two patterns in the following example:
|
||||
</p>
|
||||
<div class="sourceCode" id="cb15">
|
||||
<pre
|
||||
class="sourceCode js"
|
||||
><code class="sourceCode javascript"><span id="cb15-1"><a href="#cb15-1" aria-hidden="true" tabindex="-1"></a><span class="st">"0 1 2"</span><span class="op">.</span><span class="fu">add</span>(<span class="st">"10 20"</span>)</span>
|
||||
<span id="cb15-2"><a href="#cb15-2" aria-hidden="true" tabindex="-1"></a><span class="st">"10 [11 21] 20"</span></span></code></pre>
|
||||
</div>
|
||||
<p>
|
||||
They are similar to the previous example in that the number <code>1</code> is split in two, with its two halves
|
||||
added to <code>10</code> and <code>20</code> respectively. However, the <code>11</code> ‘remembers’ that it is a
|
||||
fragment of that original <code>1</code> event, and so is treated as having a duration of a third of a cycle,
|
||||
despite only being active for a sixth of a cycle. Likewise, the <code>21</code> is also a fragment of that
|
||||
original <code>1</code> event, but a fragment of its second half. Because the start of its event is missing, it
|
||||
wouldn’t actually trigger a sound (unless it underwent further pattern transformations/combinations).
|
||||
</p>
|
||||
<p>
|
||||
In practice, the effect of this default, implicit method for combining two patterns is that the second pattern is
|
||||
added <em>in</em> to the first one, and indeed this can be made explicit:
|
||||
</p>
|
||||
<div class="sourceCode" id="cb16">
|
||||
<pre
|
||||
class="sourceCode js"
|
||||
><code class="sourceCode javascript"><span id="cb16-1"><a href="#cb16-1" aria-hidden="true" tabindex="-1"></a><span class="st">"0 1 2"</span><span class="op">.</span><span class="at">add</span><span class="op">.</span><span class="fu">in</span>(<span class="st">"10 20"</span>)</span></code></pre>
|
||||
</div>
|
||||
<p>This makes way for other ways to align the pattern, and several are already defined, in particular:</p>
|
||||
<ul>
|
||||
<li>
|
||||
<code>in</code> - as explained above, aligns cycles, and applies values from the pattern on the right
|
||||
<em>in</em> to the pattern on the left.
|
||||
</li>
|
||||
<li>
|
||||
<code>out</code> - as with <code>in</code>, but values are applied <em>out</em> of the pattern on the left
|
||||
(i.e. <em>in</em> to the one on the right).
|
||||
</li>
|
||||
<li>
|
||||
<code>mix</code> - structures from both patterns are combined, so that the new events are not fragments but are
|
||||
created at intersections of events from both sides.
|
||||
</li>
|
||||
<li>
|
||||
<code>squeeze</code> - cycles from the pattern on the right are squeezed into events on the left. So that
|
||||
e.g. <code>"0 1 2".add.squeeze("10 20")</code> is equivalent to <code>"[10 20] [11 21] [12 22]"</code>.
|
||||
</li>
|
||||
<li>
|
||||
<code>squeezeout</code> - as with <code>squeeze</code>, but cycles from the left are squeezed into events on the
|
||||
right. So, <code>"0 1 2".add.squeezeout("10 20")</code> is equivalent to <code>[10 11 12] [20 21 22]</code>.
|
||||
</li>
|
||||
<li>
|
||||
<code>trig</code> is similar to <code>squeezeout</code> in that cycles from the right are aligned with events on
|
||||
the left. However those cycles are not ‘squeezed’, rather they are truncated to fit the event. So
|
||||
<code>"0 1 2 3 4 5 6 7".add.trig("10 [20 30]")</code> would be equivalent to
|
||||
<code>10 11 12 13 20 21 30 31</code>. In effect, events on the right ‘trigger’ cycles on the left.
|
||||
</li>
|
||||
<li>
|
||||
<code>trigzero</code> is similar to <code>trig</code>, but the pattern is ‘triggered’ from its very first cycle,
|
||||
rather than from the current cycle. <code>trig</code> and <code>trigzero</code> therefore only give different
|
||||
results where the leftmost pattern differs from one cycle to the next.
|
||||
</li>
|
||||
</ul>
|
||||
<p>
|
||||
We will save going deeper into the background, design and practicalities of these alignment functions for future
|
||||
publications. However in the next section, we take them as a case study for looking at the different design
|
||||
affordances offered by Haskell to Tidal, and JavaScript to Strudel.

<h1 data-number="9" id="comparing-strudel-and-haskell-in-use">
|
||||
<span class="header-section-number">9</span> Comparing Strudel and Haskell in use
|
||||
</h1>
|
||||
<p>
|
||||
Unlike Haskell, JavaScript lacks the ability to define custom infix operators, or change the meaning of existing
|
||||
ones. So the above Strudel example of <code>"0 1 2".add.out("10 20")</code> is equivalent to the Tidal expression
|
||||
<code>"0 1 2" +| "10 20"</code>, where the vertical bar in the operator <code>+|</code> stands for
|
||||
<code>out</code> (where <code>a |+ b</code> would be equivalent of <code>a.add.in(b)</code>).
|
||||
</p>
|
||||
<p>
|
||||
From this we can already see that Tidal tends towards brevity through mixing infix operators with functions, and
|
||||
Strudel tends towards spelling out operations which are joined together with the <code>.</code> operator. This
|
||||
then is the design trade-off of Tidal’s tersity, versus Strudel’s simplicity.
|
||||
</p>
|
||||
<p>To demonstrate this, consider the following Tidal pattern:</p>
|
||||
<pre
|
||||
class="tidal"
|
||||
><code>iter 4 $ every 3 (||+ n "10 20") $ (n "0 1 3") # s "triangle" # crush 4</code></pre>
|
||||
<p>This can be directly translated to the Strudel equivalent:</p>
|
||||
<div class="sourceCode" id="cb18">
|
||||
<pre
|
||||
class="sourceCode js"
|
||||

|
||||
</div>
|
||||
<p>Although for a more canonical Strudel expression, we would reorder it as:</p>
|
||||
<div class="sourceCode" id="cb19">
|
||||
<pre
|
||||
class="sourceCode js"
|
||||
><code class="sourceCode javascript"><span id="cb19-1"><a href="#cb19-1" aria-hidden="true" tabindex="-1"></a><span class="fu">n</span>(<span class="st">"0 1 3"</span>)<span class="op">.</span><span class="fu">every</span>(<span class="dv">3</span><span class="op">,</span> add<span class="op">.</span><span class="fu">squeeze</span>(<span class="st">"10 20"</span>))<span class="op">.</span><span class="fu">iter</span>(<span class="dv">4</span>)<span class="op">.</span><span class="fu">s</span>(<span class="st">"triangle"</span>)<span class="op">.</span><span class="fu">crush</span>(<span class="dv">4</span>)</span></code></pre>
|
||||
</div>
|
||||
<p>
|
||||
The Strudel example uses the <code>.</code> method call operator for all operations and combinations, whereas the
|
||||
Tidal example has <code>#</code> for the default method for combining patterns and uses infix operators for other
|
||||
methods. The lack of parenthesis in the Tidal example is partly due to the way that arguments are applied to
|
||||
Haskell’s functions, and partly due to the use of the <code>$</code> operator as an alternative way to establish
|
||||
precedence and control the order of evaluation.
|
||||
</p>
|
||||
<p>
|
||||
Considering the above, we argue that the Haskell syntax is a little cleaner, but that the Strudel syntax is easier
|
||||
to learn. Our informal observation is that while Haskell’s dollar <code>$</code> operator is very useful in making
|
||||
code easier to work with, it is one of the most difficult aspects of Tidal use for beginners to learn. On the
|
||||
other hand, the deeper levels of parenthesis in Strudel code can be difficult to keep track of, especially while
|
||||
coding under pressure of live musical performance. However this difficulty can be largely be mitigated by
|
||||
reordering expressions, and further mitigated by supporting editor features.
|
||||
</p>
|
||||
<p>
|
||||
With Strudel, we have little choice but to embrace the affordances and constraints offered by JavaScript, and
|
||||
while designing a domain-specific language entirely based on method calls is a challenge, through creative
|
||||
adoption of functional programming techniques like partial application, we are so far very happy with the results.
|
||||
Tidal’s functional reactive approach to pattern-making has in general translated well to JavaScript, and
|
||||
opportunities and constraints have overall traded off to create a very approachable and useable live coding
|
||||
environment.

<span class="header-section-number">9.1</span> The trade-off of flexible typing
|
||||
</h2>
|
||||
<p>
|
||||
We have identified one problem with porting Tidal to JavaScript where we have missed Haskell’s strict typing and
|
||||
type inference. In both Tidal and Strudel, time is rational, where any point in time is represented as the ratio
|
||||
of two integers. This allows representation of musical ratios such that are impossible to represent accurately
|
||||
using the more common floating point numbers. However while libraries are available that support rational numbers
|
||||
in JavaScript, the lack of strict typing means that it is easy to implement pattern methods where computationally
|
||||
expensive conversion from floating point to rational numbers are performed late, and therefore often enough to
|
||||
overload the CPUs, due to the large number of iterative calculations required to estimate a ratio for a given
|
||||
floating point number. To mitigate this problem, we might consider moving to TypeScript in the future.

<h1 data-number="10" id="future-outlook"><span class="header-section-number">10</span> Future Outlook</h1>
|

<p>

The project is still young, with many features on the horizon. As general guiding principles, Strudel aims to be

</p>
|
||||
<ol type="1">
|

<li>accessible</li>

<li>consistent with Tidal’s approach to pattern</li>
|

<li>modular and extensible</li>
|

</ol>
|
||||
<p>
|
||||
While Haskell’s type system makes it a great language for the ongoing development of Tidal’s inner representation
|
||||
of pattern, JavaScript’s vibrant ecosystem, flexibility and accessibility makes it a great host for more ad-hoc
|
||||
experiments, including interface design. For the future, it is planned to integrate additional alternative sound
|
||||
engines such as Glicol <span class="citation" data-cites="lanChaosprintGlicol2022">(Lan [2020] 2022)</span> and

|

>(<em>Faust - Programming Language for Audio Applications and Plugins</em> [2016] 2022)</span
|
||||
>. Strudel is already approaching feature parity with Tidal, but there are more Tidal functions to be ported, and
|
||||
work to be done to improve compatibility with Tidal’s mininotation. Tidal version 2.0 is under development, which
|
||||
brings a new representation for sequences to its patterns, which will then be brought to Strudel. Besides sound,
|
||||
other ways to render events are being explored, such as graphical, and choreographic output. We are also looking
|
||||
into alternative ways of editing patterns, including multi-user editing for network music, parsing a novel syntax
|
||||
to escape the constraints of javascript, and developing hardware/e-textile interfaces. In summary, there is a lot

of fun ahead.

This document introduces you to Strudel in a technical sense.
|
||||
|
||||
It is rather out of date, but there might still be useful info below.
|
||||
|
||||
If you just want to *use* Strudel, have a look at the [Tutorial](https://strudel.tidalcycles.org/tutorial/).
|
||||
|
||||
## Strudel Packages
|
||||
|
||||
There are different packages for different purposes. They..
|
||||
|
||||
- split up the code into smaller chunks
|
||||
- can be selectively used to implement some sort of time based system
|
||||
|
||||
Please refer to the individual README files in the [packages folder](https://codeberg.org/uzu/strudel/src/branch/main/packages)
|
||||
|
||||
## REPL
|
||||
|
||||
The [REPL](https://strudel.tidalcycles.org/) is the place where all packages come together to form a live coding system. It can also be seen as a reference implementation for users of the library.
|
||||
|
||||
More info in the [REPL README](https://codeberg.org/uzu/strudel/src/branch/main/packages/repl/README.md)
|
||||
|
||||
# High Level Overview
|
||||
|
||||
<img src="strudelflow.png" width="600" />
|
||||
|
||||
## 1. End User Code
|
||||
|
||||
The End User Code is written in JavaScript with added syntax sugar. The [eval package](https://github.com/tidalcycles/strudel/tree/main/packages/eval#strudelcycleseval) evaluates the user code
|
||||
after a transpilation step, which resolves the syntax sugar. If you don't want the syntax sugar, you can omit the eval package and call the native javascript `eval` instead.
|
||||
|
||||
### 🍭 Syntax Sugar
|
||||
|
||||
JavaScript Transpilation = converting valid JavaScript to valid JavaScript:
|
||||
|
||||
```js
|
||||
"c3 [e3 g3]".fast(2)
|
||||
```
|
||||
|
||||
becomes
|
||||
|
||||
```js
|
||||
mini('c3 [e3 g3]')
|
||||
.withMiniLocation([1, 0, 0], [1, 11, 11]) // source location
|
||||
.fast(2);
|
||||
```
|
||||
|
||||
- double quoted strings and backtick strings are turned into `mini` calls (single quoted strings are left as is)
|
||||
- The source location is added by chaining `withMiniLocation`, which enables the real time highlighting later
|
||||
- (psuedo) variable names that look like notes (like `c4`, `bb2` or `fs3`) are turned into strings
|
||||
- support for top level await
|
||||
- operator overloading could be implemented in the future
|
||||
|
||||
This is how it works:
|
||||
|
||||
<img src="https://github.com/tidalcycles/strudel/blob/talk/talk/public/shiftflow.png?raw=true" width="800" />
|
||||
|
||||
- The user code is parsed with a [shift parser](https://github.com/shapesecurity/shift-parser-js), generating an AST
|
||||
- The AST is transformed to resolve the syntax sugar
|
||||
- The AST is used to generate code again (shift-codegen)
|
||||
|
||||
Shift will most likely be replaced with acorn in the future, see https://github.com/tidalcycles/strudel/issues/174
|
||||
|
||||
### Mini Notation
|
||||
|
||||
Another important part of the user code is the mini notation, which allows to express rhythms in a short manner.
|
||||
|
||||
- the mini notation is [implemented as a PEG grammar](https://github.com/tidalcycles/strudel/blob/main/packages/mini/krill.pegjs), living in the [mini package](https://github.com/tidalcycles/strudel/tree/main/packages/mini)
|
||||
- it is based on [krill](https://github.com/Mdashdotdashn/krill) by Mdashdotdashn
|
||||
- the peg grammar is used to generate a parser with [peggyjs](https://peggyjs.org/)
|
||||
- the generated parser takes a mini notation string and outputs an AST
|
||||
- the AST can then be used to construct a pattern using the regular Strudel API
|
||||
|
||||
Here's an example AST:
|
||||
|
||||
```json
|
||||
{
|
||||
"type_": "pattern",
|
||||
"arguments_": { "alignment": "h" },
|
||||
"source_": [
|
||||
{
|
||||
"type_": "element", "source_": "c3",
|
||||
"location_": { "start": { "offset": 1, "line": 1, "column": 2 }, "end": { "offset": 4, "line": 1, "column": 5 } }
|
||||
},
|
||||
{
|
||||
"type_": "element",
|
||||
"location_": { "start": { "offset": 4, "line": 1, "column": 5 }, "end": { "offset": 11, "line": 1, "column": 12 } }
|
||||
"source_": {
|
||||
"type_": "pattern", "arguments_": { "alignment": "h" },
|
||||
"source_": [
|
||||
{
|
||||
"type_": "element", "source_": "e3",
|
||||
"location_": { "start": { "offset": 5, "line": 1, "column": 6 }, "end": { "offset": 8, "line": 1, "column": 9 } }
|
||||
},
|
||||
{
|
||||
"type_": "element", "source_": "g3",
|
||||
"location_": { "start": { "offset": 8, "line": 1, "column": 9 }, "end": { "offset": 10, "line": 1, "column": 11 } }
|
||||
}
|
||||
]
|
||||
},
|
||||
}
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
which translates to `seq(c3, seq(e3, g3))`
|
||||
|
||||
## 2. Querying & Scheduling
|
||||
|
||||
When the user code has been evaluated, we hopefully get a Pattern instance, which we can use to query events from.
|
||||
These events can then be used to trigger side effects in the real world. On that note, Events are mostly called Hap(s) in the codebase, because JS already has a built in `Event` class.
|
||||
|
||||
### Querying
|
||||
|
||||
> Querying = Asking a Pattern for Events within a certain time span
|
||||
|
||||
```js
|
||||
seq('c3', ['e3', 'g3']) // <--- Pattern
|
||||
.queryArc(0, 2) // query events within 0 and 2 cycles
|
||||
.map((hap) => hap.showWhole()); // make readable
|
||||
```
|
||||
|
||||
yields
|
||||
|
||||
```js
|
||||
[
|
||||
'0/1 -> 1/2: c3', // cycle 0
|
||||
'1/2 -> 3/4: e3',
|
||||
'3/4 -> 1/1: g3',
|
||||
'1/1 -> 3/2: c3', // cycle 1
|
||||
'3/2 -> 7/4: e3',
|
||||
'7/4 -> 2/1: g3',
|
||||
];
|
||||
```
|
||||
|
||||
### 🗓️ Scheduling
|
||||
|
||||
The scheduler will query events repeatedly, creating a possibly endless loop of time slices.
|
||||
Here is a simplified example of how it works
|
||||
|
||||
```js
|
||||
let step = 0.5; // query interval in seconds
|
||||
let tick = 0; // how many intervals have passed
|
||||
let pattern = seq('c3', ['e3', 'g3']); // pattern from user
|
||||
setInterval(() => {
|
||||
const events = pattern.queryArc(tick * step, ++tick * step);
|
||||
events.forEach((event) => {
|
||||
console.log(event.showWhole());
|
||||
const o = getAudioContext().createOscillator();
|
||||
o.frequency.value = getFreq(event.value);
|
||||
o.start(event.whole.begin);
|
||||
o.stop(event.whole.begin + event.duration);
|
||||
o.connect(getAudioContext().destination);
|
||||
});
|
||||
}, step * 1000); // query each "step" seconds
|
||||
```
|
||||
|
||||
## 3. Sound Output
|
||||
|
||||
The third and last step is to use the scheduled events to make sound.
|
||||
Patterns are wrapped with param functions to compose different properties of the sound.
|
||||
|
||||
```js
|
||||
note("[c2(3,8) [<eb2 g1> bb1]]") // sets frequency
|
||||
.s("<sawtooth square>") // sound source
|
||||
.gain(.5) // turn down volume
|
||||
.cutoff(sine.range(200,1000).slow(4)) // modulated cutoff
|
||||
.slow(2)
|
||||
.out().logValues()`,
|
||||
]}
|
||||
/>
|
||||
```
|
||||
|
||||
Here is an example Hap value with different properties:
|
||||
|
||||
```js
|
||||
{ note: 'a4', s: 'sawtooth', gain: 0.5, cutoff: 267 }
|
||||
```
|
||||
<img src="waa-nodes.png" width="600" />
|
||||
|
||||
<div className="text-left">
|
||||
|
||||
- Patterns represent just values in time!
|
||||
- Suitable for any time based output (music, visuals, movement, .. ?)

/***

* Allows you to switch a pattern between different 'timelines'. This is particularly useful when
|

* live coding, for example when you want to cue a pattern up to play from its start.
|
||||
*
|
||||
* Timelines are specified by number, so that if you had a pattern like
|
||||
* `n("<0 1 2 3>").s("num").timeline(1)` playing, then changed the '1'
|
||||
* to '2', it would always align '0' to the nearest cycle. You will likely want to trigger
|
||||
* an evaluation a little bit before the cycle starts, to avoid missing events.
|
||||
*
|
||||
* After the first use, a timeline will continue with the same 'offset'. That is, if you change
|
||||
* a pattern without changing its timeline number, it will stay on that timeline without resetting.
|
||||
*
|
||||
* Rather than incrementing a timeline to reset it, it's easier to negate it, e.g. by switching between `-2`
|
||||
* and `2`. This is because when you negate a timeline it will always reset.
|
||||
*
|
||||
* You can also pattern the timeline if you want, to create strange resetting patterns.

* n("<0 1 2 3>(3,8)")
