-
-## Customize This Theme
-
-edit: removed, as css styles have been replaced with tailwind styles
-
-### Site metadata
-
-`src/config.ts` contains several data objects that describe metadata about your site like title, description, default language, and Open Graph details. You can customize these to match your project.
-
-## Page metadata
-
-Astro uses frontmatter in Markdown pages to choose layouts and pass properties to those layouts. If you are using the default layout, you can customize the page in many different ways to optimize SEO and other things. For example, you can use the `title` and `description` properties to set the document title, meta title, meta description, and Open Graph description.
-
-```markdown
----
-title: Example title
-description: Really cool docs example that uses Astro
-layout: ../../layouts/MainLayout.astro
----
-
-# Page content...
-```
-
-For more SEO related properties, look at `src/components/HeadSEO.astro`
-
-### Sidebar navigation
-
-The sidebar navigation is controlled by the `SIDEBAR` variable in your `src/config.ts` file. You can customize the sidebar by modifying this object. A default, starter navigation has already been created for you.
-
-```ts
-export const SIDEBAR = {
-  en: [
-    { text: "Section Header", header: true },
-    { text: "Introduction", link: "en/introduction" },
-    { text: "Page 2", link: "en/page-2" },
-    { text: "Page 3", link: "en/page-3" },
-
-    { text: "Another Section", header: true },
-    { text: "Page 4", link: "en/page-4" },
-  ],
-};
-```
-
-Note the top-level `en` key: This is needed for multi-language support. You can change it to whatever language you'd like, or add new languages as you go. More details on this below.
-
-### Multiple Languages support
-
-The Astro docs template supports multiple languages out of the box. The default theme only shows `en` documentation, but you can enable multi-language support features by adding a second language to your project.
-
-To add a new language to your project, you'll want to extend the current `src/pages/[lang]/...` layout:
-
-```diff
- 📂 src/pages
- ┣ 📂 en
- ┃ ┣ 📜 page-1.md
- ┃ ┣ 📜 page-2.md
- ┃ ┣ 📜 page-3.astro
-+ ┣ 📂 es
-+ ┃ ┣ 📜 page-1.md
-+ ┃ ┣ 📜 page-2.md
-+ ┃ ┣ 📜 page-3.astro
-```
-
-You'll also need to add the new language name to the `KNOWN_LANGUAGES` map in your `src/config.ts` file. This will enable your new language switcher in the site header.
-
-```diff
-// src/config.ts
-export const KNOWN_LANGUAGES = {
-  English: 'en',
-+  Spanish: 'es',
-};
-```
-
-Last step: you'll need to add a new entry to your sidebar, to create the table of contents for that language. While duplicating every page might not sound ideal to everyone, this extra control allows you to create entirely custom content for every language.
-
-> Make sure the sidebar `link` value points to the correct language!
-
-```diff
-// src/config.ts
-export const SIDEBAR = {
-  en: [
-    { text: 'Section Header', header: true, },
-    { text: 'Introduction', link: 'en/introduction' },
-    // ...
-  ],
-+  es: [
-+    { text: 'Encabezado de sección', header: true, },
-+    { text: 'Introducción', link: 'es/introduction' },
-+    // ...
-+  ],
-};
-
-// ...
-```
-
-If you plan to use Spanish as the default language, you just need to modify the redirect path in `src/pages/index.astro`:
-
-```diff
-<script>
-- window.location.pathname = `/en/introduction`;
-+ window.location.pathname = `/es/introduction`;
-</script>
-```
-
-You can also remove the above script and write a landing page in Spanish instead.
-
-### What if I don't plan to support multiple languages?
-
-That's totally fine! Not all projects need (or can support) multiple languages. You can continue to use this theme without ever adding a second language.
-
-If that single language is not English, you can just replace `en` in directory layouts and configurations with the preferred language.
-
-### Search (Powered by Algolia)
-
-[Algolia](https://www.algolia.com/) offers a free service to qualified open source projects called [DocSearch](https://docsearch.algolia.com/). If you are accepted to the DocSearch program, provide your API Key & index name in `src/config.ts` and a search box will automatically appear in your site header.
-
-Note that Aglolia and Astro are not affiliated. We have no say over acceptance to the DocSearch program.
-
-If you'd prefer to remove Algolia's search and replace it with your own, check out the `src/components/Header.astro` component to see where the component is added.

+
+# Frequently Asked Questions
+
+This page contains frequently asked questions, with answers. Usually, the topic is explained in more detail in a section which is linked in the answer.
+
+## Is Strudel/Tidal free?
+
+Yes - there is no charge, this is a collective open source project, and the music you make with it is your own. However if you can, please make a one-off or regular donation to our [opencollective fund](https://opencollective.com/tidalcycles), that supports the software and cultural development of Strudel and other Uzu languages.
+
+While there is no charge there are some caveats, e.g.:
+
+- the source code must stay free, i.e. you cannot distribute strudel or tidal as part of projects with incompatible licenses - see the [license](https://www.gnu.org/licenses/agpl-3.0.en.html) for details.
+- the contributed examples and tracks are also separately licensed, and must not e.g. be used to train AI models without permission.
+
+## How do I try out the latest features?
+
+The main, stable strudel website is [strudel.cc](https://strudel.cc/). There is also [warm.strudel.cc](https://warm.strudel.cc), known as "warm strudel", which has the latest development features. You might find warm strudel has bug fixes and features that the main website doesn't, but it will often be less stable and probably not suitable for important performances.
+
+Alternatively, you can run strudel locally to try out the latest features. You can find development-oriented [instructions for that here](https://codeberg.org/uzu/strudel/src/branch/main/CONTRIBUTING.md#project-setup).
+
+You can see the [latest changes here](https://codeberg.org/uzu/strudel/pulls?q=&type=all&sort=recentupdate&state=closed&labels=&milestone=0&project=0&assignee=0&poster=0), as 'pull requests'.
+
+## How to record or export audio?
+
+Strudel is not a digital audio workstation and does not operate following the same principles shared by most traditional audio softwares. However, there are multiple ways to record the audio -- and video -- output of Strudel:
+
+- Use the 'export' tab to render and download as an audio file.
+- capture the raw stereo signal coming out of your web browser. You will need an external audio editor/DAW such as Reaper/Audacity/Ardour, etc.
+- use the alternative SuperDirt audio engine. Read [this page](/learn/input-output/#oscsuperdirtstrudeldirt) to know more about it.
+- capture the audio/video stream using a capture tool such as [OBS](https://obsproject.com/fr), which is designed for live streaming, but also works very well for recording.
+- don't record anything and code it again in front of your friends.
+
+## Can I use strudel with my IDE?
+
+Yes you can. There are experimental modes, made by community members, for several IDEs such as:
+
+- VS Code: [Strudel VS](https://marketplace.visualstudio.com/items?itemName=cmillsdev.strudelvs): an experimental mode for Microsoft VSCode. A revived version of [TidalStrudel](https://marketplace.visualstudio.com/items?itemName=roipoussiere.tidal-strudel), which is defunct.
+- nvim: [strudel.nvim](https://github.com/gruvw/strudel.nvim)
+
+## How can I use my own samples?
+
+There are multiple ways to load your sample collection. Some methods are good for quick experimentation, some others are good to share your audio collection with other musicians:
+
+- Import folders [from the interface](/learn/samples/#from-disk-via-import-sounds-folder). These are stored locally in your web browser, and not uploaded.
+- Serve a folder of samples locally using the [strudel 'sampler' commandline tool](https://strudel.cc/learn/samples/#from-disk-via-strudelsampler). This can be most reliable method, but requires [nodejs](https://nodejs.org) to be installed.
+- Host your sound library online on the web and [load them from an URL](/learn/samples/#loading-custom-samples)
+
+## Can I use Strudel with AI/LLM tools?
+
+You are free to do what you like with Strudel, within the terms of the free/open source AGPLv3 license.
+However as a community we are interested in exploring human creativity. AI is _way_ over-hyped right now,
+including by people with very shady motives. Many in the community are very wary of people training models
+on their tunes that they've poured their love into. So please keep discussion and questions around AI and
+LLMs to channels dedicated to the topic and be fully respectful of other people's work.
+
+Furthermore, tools like ChatGPT generally give wrong answers. Please don't ask the community to fix those
+answers for you, as generally they will be timewasting nonsense.
+
+Human questions are always welcome!
+
+## Where can I download loads of patterns to train my LLM?
+
+You cannot, as there is no such place. For details regarding our stance towards AI/LLM, see [above](/learn/faq/#can-i-use-strudel-with-aillm-tools)
+
+## How to run offline?
+
+Strudel works offline just fine! There are multiple techniques for this, see [this explanation](learn/pwa/#using-strudel-offline).
+
+## How to change tempo? How do I translate BPM to cpm?
+
+Strudel works in cycles, rather than beats, but if you assume a certain number of beats per cycle, you can convert between them.
+
+For example, if you have your tempo in beats per minute and use 4 beats per cycle (e.g. if your track is in 4/4ths) then you can do `setcpm(BPM/4)`
+where BPM is your beats per minute.
+
+If you have a different number of beats per bar or are using more or less beats per cycle (e.g. If you want to put only half a bar or
+two bars into one cycle), adjust accordingly.
+
+## Where can I see all the functions?
+
+If you pop open the sidetab of strudel.cc (small white < on the right hand side), there is a tab "reference" which lists all the functions of strudel.
+
+## Where can I see all the samples and synths?
+
+If you pop open the sidetab of strudel.cc (small white < on the right hand side), there is a tab "sounds" which lists all the drum machines, samples and synths currently loaded.
+
+## How do I use this exactly like a DAW?
+
+Strudel has different design aims for a DAW, and so treating it like one will likely be frustrating. DAWs are geared towards
+sequencing notes over time in predictable ways, whereas Strudel and similar Uzu languages are geared towards combining and
+transforming patterns in ways that can be hard to predict.
+
+If you want to emulate the functionality of a DAW in Strudel, you'll have to identify the operations
+executed by the DAW (sequencing, repeating, applying filters and envelopes) and write code that is equivalent to these
+operations. For example in Strudel, the 'arrange' and 'pick' methods are useful for sequencing patterns over time (see question on these later in this document).
+
+You might still find that the typical DAW workflow is not really adapted to live coding because, despite
+both being ways of making music on the computer, they are two very different tools. You could then adapt your way of proceeding
+to the medium of code, which might mean leaving more place to serendipity and writing code that you don't predict the output of.
+
+## Why doesn't everyone just use a DAW?
+
+There is no easy answer to this question. Here are some thoughts:
+
+- Live coding tools such as Strudel are excellent for improvising music and visuals using a computer. DAWs are valuable and robust companions for other activities such as producing, mastering and mixing audio, among other usages. Using a tool does not exclude from using any another tool, just build a toolbox.
+
+- Live coding has developed over decades as a distinct creative practice. For example, live coding artists like to show their screens while playing in front of an audience. It is an essential part of what they do, of the way they share their activity with everybody.
+
+- Code is a human language, it is made for other humans to read it. You can read the code and enjoy the music too. It has meaning, value, and there might even be something poetic/important about it! - Strudel is free and open source, you can inspect the code, reshape it, contribute to it if you can/want. It is not opaque and this matters for many people. There is no black box, no obscure abstractions, no business model, no user tracking or hidden features. We need open tools in the arts! - Live coders don't all shy away from using DAWs. Many use them all of the time, especially when it makes their life easier for... live coding!
+
+- Code is an artistic material like any other. There is something valuable in the process of making music through code. More generally speaking, it is nice to tackle creative problems through the use of a programming language: creative thinking, building up your own solutions, DIY approach to music-making, unexpected outcome of algorithms, funny human errors, etc.
+
+- There are pianos and trumpets in your DAW: why do people continue playing the piano or the trumpet? Think of live coding tools as instruments that you activate through the act of programming.
+
+## How can I interface Strudel with my favorite music software? What can I do with it?
+
+Strudel can send [MIDI and OSC](/learn/input-output/), which are protocols for communicating musical information.
+
+Other music software (or hardware!) can then listen to these messages and process them according to its capabilities.
+
+A simple example would be to send livecoded audio to a DAW like Ardour on different tracks and then use it to mix them.
+
+You could also send the MIDI of a sequenced pattern to Musescore and then have it transcribe your livecoded work as a musical score.
+
+You could also send MIDI to your hardware synths, if you like their sound.
+
+## How do I use this in my closed source webgame or other software?
+
+You don't. You need to license your game to a free/open source license fulfill the [AGPLv3 license](https://codeberg.org/uzu/strudel/src/branch/main/LICENSE) Strudel is distributed under.
+
+## How to play different patterns simultaneously?
+
+Using the $ operator, several patterns can be played at once:
+
+<MiniRepl
+  client:idle
+  tune={`$: s("bd*4").bank("tr707")
+$: s("- sd").bank("tr909")`}
+/>
+
+See also [stack](intro/#combining-patterns)
+
+## Is it possible to mute a pattern?
+
+With an additional underscore, a pattern can be muted.
+
+<MiniRepl
+  client:idle
+  tune={`$: s("bd*4").bank("tr707")
+_$: s("- sd").bank("tr909")`}
+/>
+
+See also [hush](/learn/conditional-modifiers/#hush)
+
+## How can I arrange in Strudel using `mask`?
+
+With mini-notation, using the `<>` and `!` operators, you can try something like
+
+```
+.mask("<0!24 1!40>")
+```
+
+It mutes a pattern for 24 cycles and plays it for 40. You would gain 64 cycles total, a multiple of 2/4/8 commonly used in western music.
+
+If each cycle is a bar, as a starting point, you could write a mask like that for any pattern:
+
+```
+.mask("<0!16 0!16 0!16 0!16 0!16 0!10>")
+```
+
+It mutes it throughout.
+
+For arranging, you could add the same mask to each part and replace some zeroes with ones in your different masks to make parts play.
+
+If you use `.mask()` on different patterns mess up your counting, then patterns do not align anymore.
+On the other hand, doing that on purpose is one of the things that could be considered a strength of tidalcycles and Strudel.
+You can make things quite lively and more organic with a little (controlled) interference, according to your own taste.
+And you are free to arrange in cycles like 3, 6 or 9 too.
+
+To modify everything at once, you could try all and when, for example:
+
+```
+all(x=>x.when("<0!7 1>", x=>x.lpf(saw.range(200, 2000))))
+```
+
+This would lowpass filter sweep everything every 8 cycles.
+
+## How can I arrange in Strudel using `arrange` or `pick`?
+
+Take [Pachelbel's Canon in D](https://en.wikipedia.org/wiki/Pachelbel%27s_Canon#Analysis) as an example which has 4 voices (one cello and 3 violins) which have repeating patterns, as seen in the link above.
+
+The following snipped defines the patterns as constants which can then be used for the different voices. `arrange` takes multiple arguments, which are each a number of cycles and a pattern which is played for the number of cycles, wrapped in `[]` If the pattern is shorter than the number, it is repeated.
+
+<MiniRepl client:idle tune={`const cello = note(
+  "<[d3 a2 b2 f#2] [g2 d3 g2 a2]>")
+  .color("grey").sound("gm_tremolo_strings:3")
+ const violin_p1 = note(
+  "<[f#5 e5 d5 c#5] [b4 a4 b4 c#5]>")
+  .color("blue")
+ const violin_p2 = note(
+  "<[d5 c#5 b4 a4] [ g4 f#4 g4 f#4]>")
+ .color("green")
+ const violin_p3 = note(
+  "<[d4 f#4 a4 g4 f#4 d4 f#4 e4] [d4 b3 d4 a4 g4 b4 a4 g4]>")
+  .color("purple")
+ const violin_p4 = note(
+  "<[f#4 d4 e4 c#5 d5 f#5 a5 a4] [b4 g4 a4 f#4 d4 d5 [d5@3 c#5]@2]>")
+  .color("red")
+
+cello$: arrange(
+  [2, silence],
+  [18,cello])
+ violin1$: arrange(
+[4,silence],
+[2,violin_p1], [2,violin_p2],
+[2,violin_p3], [2,violin_p4],
+[2,violin_p1], [2,violin_p2],
+[2,violin_p3], [2,violin_p4]
+).sound("gm_tremolo_strings:0")
+violin2$: arrange(
+  [6,silence], [2,violin_p1], 
+  [2,violin_p2], [2,violin_p3], 
+  [2,violin_p4], [2,violin_p1], 
+  [2,violin_p2], [2,violin_p3] 
+  ).sound("gm_tremolo_strings:1")
+ violin3$: arrange(
+[8,silence],
+[2,violin_p1], [2,violin_p2],
+[2,violin_p3], [2,violin_p4],
+[2,violin_p1], [2,violin_p2]
+).sound("gm_tremolo_strings:2")
+
+    all(x => x.release(.2))
+
+`} />
+
+Alternatively, you can also put the different patterns for the violins into one single array (`const violins = [violin_p1, violin_p2, violin_p3, violin_p4]`) and use a pattern as an index to `pick` the nth element of that array. This replaces the voices defined above. Here you use `0@2` to specifiy that the first item (i.e. with index `0`) is played for `2` cycles.
+
+`pick` has better highlighting than `arrange`:
+
+<MiniRepl client:idle tune={`const cello = note(
+  "<[d3 a2 b2 f#2] [g2 d3 g2 a2]>")
+  .color("grey").sound("gm_tremolo_strings:3")
+ const violin_p1 = note(
+  "<[f#5 e5 d5 c#5] [b4 a4 b4 c#5]>")
+  .color("blue")
+ const violin_p2 = note(
+  "<[d5 c#5 b4 a4] [ g4 f#4 g4 f#4]>")
+ .color("green")
+ const violin_p3 = note(
+  "<[d4 f#4 a4 g4 f#4 d4 f#4 e4] [d4 b3 d4 a4 g4 b4 a4 g4]>")
+  .color("purple")
+ const violin_p4 = note(
+  "<[f#4 d4 e4 c#5 d5 f#5 a5 a4] [b4 g4 a4 f#4 d4 d5 [d5@3 c#5]@2]>")
+  .color("red")
+
+const violins = [violin_p1, violin_p2, violin_p3, violin_p4]
+
+cello$: "<~@2 0@18>".pick([cello])
+violin1$: "<~@4 0@2 1@2 2@2 3@2 0@2 1@2 2@2 3@2>".pick(violins)
+.sound("gm_tremolo_strings:0")
+violin2$: "<~@6 0@2 1@2 2@2 3@2 0@2 1@2 2@2>".pick(violins)
+.sound("gm_tremolo_strings:1")
+violin3$: "<~@8 0@2 1@2 2@2 3@2 0@2 1@2 >".pick(violins)
+.sound("gm_tremolo_strings:2")
+all(x => x.release(.2))
+`} />
+
+The `pick` method also works with jsons which have named elements, which makes it easier to read, see the [here](/learn/conditional-modifiers/#pick). `pickRestart` restarts the pattern upon picking it which can make a difference if the duration of the pick indexes doesn't line up with the patterns which are picked - which is not the case here.
+
+Try adding `.punchcard()` after the `release(.2)` for a visualization.
+
+## I saw Switch Angel using functions which I cannot find in the reference (e.g. `trancegate`). How do I make it work?
+
+Methods like `trancegate()`, `rlpf()` and `acidenv()` are currently not pattern methods which come natively with strudel.
+
+They are part of a script/prebake for strudel which was written by Switch Angel and published [here](https://github.com/switchangel/strudel-scripts)
+
+You can find the instructions how to use that script in the readme.md there.
+
+## Is there difference between `n` and `note`?
+
+They are not aliases of each other, in contrast to `s` and `sound`.
+
+The method `note` is used to reference a certain note (either as its name, such as `c` or `b2` or the midi number `69`, for example `note("c3 e3 g3")`).
+
+On the other hand, `n` is a way to reference the nth index of something. This something can be a scale (eg `n("0 2 4").scale("C:major")`) , but it can also be a particular note in a chord (see https://strudel.cc/recipes/recipes/#arpeggios for an example) .
+
+The method `n` can also be used for something completely unrelated to notes, in particular the nth sample from a sample map `s("hh*8").bank("RolandTR909").n("0 1 2 3")`.
+
+<MiniRepl
+  client:idle
+  tune={`
+        n("<[0 1 2 3@3 -@2] [3 2 1 0@3 -@2] >")
+        .scale("A:minor:pentatonic")
+        .s("gm_acoustic_guitar_steel").n("<0 1 2 3>/2")`}
+/>
+
+Note that `n` is not the only way that functions use indices, some take numbered patterns instead.
+
+## Is there a cheat sheet for all symbols?
+
+Yes!

+@3  elongates the item by a factor of 3 (other numbers work too, even non-integer, but for numbers between 0 and 1 you need a leading zero like this: @0.5)
+@   after an item: elongates the item once (multiple @ work too c @ @ is the same as c@3)

 - If :w logs but evaluation doesn't apply, ensure Vim keybindings are active and try again. You can also use Ctrl+Enter as a fallback.
 - For :q / gc, ensure focus is inside the editor. If an error occurs, reload the page to reset editor state and try again.
+
+## Adding custom keybindings
+
+To add custom keybindings the `Vim` object can be used (either from within a pattern or in a prebake script)
+
+Example:
+
+```javascript
+// Map 'jk' to Escape in normal mode
+Vim.map('jk', '<Esc>', 'insert');
+// Map 'U' to :w (Evaluate the current code)
+Vim.map('U', ':w<CR>', 'normal');
+// Map 'Q' to :q — Stop/pause playback
+Vim.map('Q', ':q<CR>', 'normal');
+// Map 'J' to find next '$' (jump to next label)
+Vim.map('J', '/\\$<CR>', 'normal');
+// Map 'K' to find previous '$' (jump to previous label)
+Vim.map('K', '?\\$<CR>', 'normal');
+```
