+## 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

+    <p>
+      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.
+    </p>
+    <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.

+    <h1 data-number="3" id="representing-patterns">
+      <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">=&gt;</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"
+      ><code class="sourceCode javascript"><span id="cb2-1"><a href="#cb2-1" aria-hidden="true" tabindex="-1"></a>[{ <span class="dt">value</span><span class="op">:</span> <span class="st">&#39;c3&#39;</span><span class="op">,</span> <span class="dt">begin</span><span class="op">:</span> <span class="dv">0</span><span class="op">,</span> <span class="dt">end</span><span class="op">:</span> <span class="dv">1</span><span class="op">/</span><span class="dv">2</span> }<span class="op">,</span></span>
+<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">&#39;e3&#39;</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">&#39;g3&#39;</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.

+    <h1 data-number="4" id="making-patterns"><span class="header-section-number">4</span> Making Patterns</h1>
+    <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.
+    </p>
+    <div class="sourceCode" id="cb3">
+      <pre
+        class="sourceCode js"
+      ><code class="sourceCode javascript"><span id="cb3-1"><a href="#cb3-1" aria-hidden="true" tabindex="-1"></a><span class="fu">note</span>(c3<span class="op">,</span> [e3<span class="op">,</span> g3])</span></code></pre>
+    </div>
+    <p>
+      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.].
+    </p>
+    <div class="sourceCode" id="cb4">
+      <pre
+        class="sourceCode js"
+      ><code class="sourceCode javascript"><span id="cb4-1"><a href="#cb4-1" aria-hidden="true" tabindex="-1"></a><span class="fu">note</span>(<span class="st">&quot;c3 [e3 g3]&quot;</span>)</span></code></pre>
+    </div>
+    <p>
+      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

+      <li><code>brackets</code>: elements inside brackets are divided equally over the time of their parent</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

+      <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. -->

+      <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.

+      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>

+    <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 &amp; 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 class="sourceCode" id="cb7">
+      <pre
+        class="sourceCode js"
+      ><code class="sourceCode javascript"><span id="cb7-1"><a href="#cb7-1" aria-hidden="true" tabindex="-1"></a><span class="st">&quot;c3 [e3 g3]*2&quot;</span></span></code></pre>
+    </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">&quot;c3 [e3 g3]*2&quot;</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:

+    </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:

+    <p>
+      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.

+    <h2 data-number="7.3" id="output"><span class="header-section-number">7.3</span> Output</h2>
+    <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.

+    <p>
+      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:

+      The above example will create an <code>OscillatorNode</code> for each event, where the frequency is controlled by

+      <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">

+    </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:

+      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">&quot;0 1 2&quot;</span><span class="op">.</span><span class="at">add</span><span class="op">.</span><span class="fu">in</span>(<span class="st">&quot;10 20&quot;</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.
+    </p>
+    <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 &quot;10 20&quot;) $ (n &quot;0 1 3&quot;) # s &quot;triangle&quot; # crush 4</code></pre>
+    <p>This can be directly translated to the Strudel equivalent:</p>
+    <div class="sourceCode" id="cb18">
+      <pre
+        class="sourceCode js"
+      ><code class="sourceCode javascript"><span id="cb18-1"><a href="#cb18-1" aria-hidden="true" tabindex="-1"></a><span class="fu">iter</span>(<span class="dv">4</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">&quot;10 20&quot;</span>)<span class="op">,</span> <span class="fu">n</span>(<span class="st">&quot;0 1 3&quot;</span>)<span class="op">.</span><span class="fu">s</span>(<span class="st">&quot;triangle&quot;</span>)<span class="op">.</span><span class="fu">crush</span>(<span class="dv">4</span>)))</span></code></pre>
+    </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">&quot;0 1 3&quot;</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">&quot;10 20&quot;</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">&quot;triangle&quot;</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.
+    </p>
+    <h2 data-number="9.1" id="the-trade-off-of-flexible-typing">
+      <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.
+    </p>
+    <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
+      Faust
+      <span class="citation" data-cites="FaustProgrammingLanguage2022"
+        >(<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.

+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, .. ?)
+
+### Supported Outputs
