+ * Turns numbers into notes in the given EDO scale (zero indexed).
+ *
+ * An EDO scale definition looks like this:
+ *
+ * e.g. C:LLsLLLs:2:1 <- this is the C major scale, 12 EDO
+ *
+ * e.g. C:LLsLLL:3:1 <- this is the Gorgo 6 note scale, 16 EDO
+ *
+ * An EDO scale, e.g. C:LLsLLLs:2:1, consists of a root note (e.g. C)
+ * followed by semicolon (':')
+ * and then a [Large/small step notation sequence](https://en.xen.wiki/w/MOS_scale)
+ * (e.g. LLsLLLs)
+ * followed by semicolon, then the large step size (e.g. 2)
+ * followed by semicolon, then the small step size (e.g. 1).
+ *
+ * The number of divisions of the octave is calculated as the sum
+ * of the steps in the EDO scale definition.
+ *
+ * e.g. C:LLsLLLs:2:1 is 2+2+1+2+2+2+1 = 12 EDO, 7 note scale
+ *
+ * e.g. C:LLsLLL:3:1 is 3+3+1+3+3+3 = 16 EDO, 6 note scale

 # @strudel/transpiler
 
-This package contains a JS code transpiler with the following features:
+This package contains a JS code transpiler with a plugin system that can be used to transform the code.
+
+A plugin can be registered via a `registerTranspilerPlugin` call :
+
+```js
+registerTranspilerPlugin({
+  walk: (context) => ({
+    enter: function(node, parent, prop, index) {},
+    leave: function(node, parent, prop, index) {}
+  })
+})
+```
+
+where the enter/leave functions (both optional) follow the `estree-walker` walk API.
+
+4 plugins are currently hosted inside `@strudel/transpiler`
+
+- mini: add locations of mini notation strings (double quoted or backticked) for highlighting
+- widgets: add handling of sliders & draw widgets
+- sample: make it possible to call a sample without await
+- kabelsalat: transform the code to handle the `K(..)` kabelsalat notation
+
+it also
 
-- add locations of mini notation strings (double quoted or backticked) for highlighting
-- converts pseudo note variables to note strings
 - adds return statement to the last expression
+- handles label capturing for block-based eval
 
 ## Install

+ * If haps have edoSize param set, such as from the output of `xen("31edo")`,

+ * Transposes the frequency by `amt` edoSteps

+ * @param {number} amt

+title: Low-frequency oscillators (LFO)
+layout: ../../layouts/MainLayout.astro
+---
+
+import { MiniRepl } from '../../docs/MiniRepl';
+import { JsDoc } from '../../docs/JsDoc';
+
+# Low frequency oscillators (LFO)
+
+A low frequency oscillator (or short LFO) is a common way on synthesizers to continuously modulate various signals.
+
+This documentation is an interactive version of glossing's tutorial https://www.youtube.com/watch?v=11frBA9L638
+
+## Signals vs LFOs
+
+In Strudel, there are two ways to modulate:
+
+1. [signals](/learn/signals/) for pattern-level modulation
+2. `lfo` (this page) for audio-level modulation
+
+## Applying an LFO
+
+Here, the LFO will change the frequency of the `saw`. Put a comment like this `//.lfo()` to see and hear how it changes, and remove the comment again.
+
+<MiniRepl
+  client:idle
+  tune={`
+s("saw").lfo() 
+  .lpf(800)
+  ._spectrum({height: 300, width: 800})`}
+/>
+
+By default, the LFO will modulate the control parameter which is right before `.lfo()`:
+
+<MiniRepl
+  client:idle
+  tune={`
+s("saw")
+  .lpf(800).lfo() 
+  ._spectrum({height: 300, width: 800})`}
+/>
+
+Here, the LFO will modulate the low pass filter `.lpf`.
+
+## Moving away from the default
+
+The following sections explain how pass parameters to `.lfo`. Similar to `._spectrum` above, almost all the configuration of `lfo` lives inside a json object, starting with `{` and ending with `}`.
+All the parameters (except `id`) are written as `key: value` inside and separated by `,`.
+
+The reference refers to them as `config.key`, i.e. for the following one as `config.control` but you use them like below.
+
+## Control
+
+`control` determines which parameter will be modulated. This allows you to place your `lfo` at different places,
+not necessarily immediately after the controlled parameter.
+
+Here, we place `lfo` after the `s`, but it modulates the low pass filter.
+
+<MiniRepl
+  client:idle
+  tune={`
+s("saw")
+  .lfo({control:'lpf'})
+  .lpf(800)
+  ._spectrum({height: 300, width: 800})`}
+/>
+You can even influence parameters which are always present, even if you haven't explicitly written them, like `gain`.
+
+<MiniRepl
+  client:idle
+  tune={`
+s("saw")
+  .lfo({control:'gain'})
+  .lpf(800)
+  ._spectrum({height: 300, width: 800})`}
+/>
+
+`control` has an alias `c`.
+
+## Rate
+
+`rate` determines how often the `lfo` oscillates per second:
+
+<MiniRepl
+  client:idle
+  tune={`
+ s("saw")
+  .lfo({c:'gain', rate:"<2 4>"})
+  .lpf(800)
+  ._spectrum({height: 300, width: 800})`}
+/>
+The alias of `rate` is `r`.{' '}
+
+## Sync
+
+Instead of controlling the frequency with `rate` by setting a frequency in Hz, you can use `sync`
+to snychronize your lfo with your other patterns.
+
+`sync` expresses this frequency as "times per cycle"
+
+Try removing the `sync: "<2 4 8 0.5 >"` from the pattern and notice that there is something not in sync.
+
+<MiniRepl
+  client:idle
+  tune={`
+$: s("bd*4").bank("TR909").postgain(0.5)
+$: s("saw")
+  .lpf(800)
+  .lfo({sync: "<2 4 8 0.5 >"})
+  ._spectrum({height: 300, width: 800})`}
+/>
+
+You can put patterns into the parameters of `lfo` if you want them to change over time, as seen above.
+
+## Relative Depth
+
+`.depth` is relative depth, a value of 1 (the default) means that
+the value goes above and below by half of the value which is being modulated
+
+E.g. for depth `1`, it modulates the frequency to oscillate between 32 = (64/2) and 96 (= 64 + 64/2).
+
+<MiniRepl
+  client:idle
+  tune={`
+s("saw").freq(64)
+  .lfo({r: 2, depth: "<1 2 3>"})
+  .lpf(800)
+  ._spectrum({height: 300, width: 800})`}
+/>
+The `freq` is not needed here, as this is the default frequency, it's just for instructive purposes.
+
+The aliases of `depth` are `dr` and `dep`.
+
+## Absolute Depth
+
+`depthabs` controls the absolute modulation depth. For example you can modulate
+the low pass filter by exactly 250 Hz up and below:
+
+<MiniRepl
+  client:idle
+  tune={`
+s("saw")
+  .lpf(800)
+  .lfo({r: 2, depthabs: "250"})`}
+/>
+
+The alias of `depthabs` is `da`.
+
+## DC offset
+
+If you don't want to go up or down by the same amount with your modulation, then you can shift the center of the modulation with `dcoffset`.
+The default value is -0.5, which is the middle point between:
+"dcoffset = 0: All modulations increase the control parameter (or keep it constant)"
+"dcoffset = -1: All modulations decrease the control parameter (or keep it constant)"
+
+Other values will work as well.
+
+<MiniRepl
+  client:idle
+  tune={`
+s("saw")
+  .lpf(600)
+  .lfo({r: 2, da: "200", dcoffset: "<-0.5 -1 -0.5 0>"})`}
+/>
+The marvellous alias of `dcoffset` is `dc`.
+
+## Shape
+
+You can change the shape of the modulation with `shape`. The default is `triangle`, but other shapes are available too:
+
+<MiniRepl
+  client:idle
+  tune={`
+s("saw")
+  .lpf(800)
+  .lfo({r: 2, shape: "<triangle sine ramp saw square>"}) `}
+/>
+You can add `._spectrum()` to see the shape of the modulations in the spectrum.
+
+You can also get these shapes by using numbers:
+
+| Shape    | number |
+| -------- | ------ |
+| triangle | 0      |
+| sine     | 1      |
+| ramp     | 2      |
+| saw      | 3      |
+| square   | 4      |
+
+this way, you can use a function like `irand` to generate numbers:
+
+<MiniRepl
+  client:idle
+  tune={`
+s("saw")
+  .lpf(800)
+  .lfo({r: 2, shape: irand(4)}) `}
+/>
+
+The alias of `shape` is `sh`.
+
+## Skewing some shapes
+
+You can influence some of the shapes (`triangle` and `square`) in more detail.
+
+The default skew is 0.5, it does different things for these two.
+
+For `triangle`, it skews the top of the triangle to the left or right,
+where 0 makes it look like `saw` and 1 makes it look like `ramp`.
+
+For `square`, the skew influences the pulse width (see reference for `pulse` and `.pw`):
+
+<MiniRepl
+  client:idle
+  tune={`
+s("saw")
+  .lpf(800)
+  .lfo({r: 2, sh: "<triangle square>/5", 
+    skew: "<0 0.25 0.5 0.75 1>"}) `}
+/>
+The alias of `skew` is `sk`.{' '}
+
+## Curve
+
+You can change the curves of your lfo and can make it more intense.
+The default value is 1. Writing numbers greater than one can make it more intense,
+numbers between 0 and 1 will make it less intense.
+This will raise the lfo to the power of curve, so larger numbers (such as 10) can have very unexpected results.
+
+<MiniRepl
+  client:idle
+  tune={`
+s("saw")
+  .lpf(800)
+  .lfo({r: 2, sh: "<triangle>", curve: "<1.3 1 0.75 1>"}) `}
+/>
+## Referencing your lfos with id
+
+All the lfos are numbered from the first starting with 0, the second having an `id` of 1 and so on.
+
+You can refer to this in a later call if you want to modify a specific `lfo`.
+
+The `id` is outside of the config json (which is different from the other parameters of `lfo()`
+
+Try out how the sound changes when you replace the 0 with a 1.
+
+<MiniRepl
+  client:idle
+  tune={`
+s("saw").lfo().lpf(800)
+.lfo({s: "<4 8 0.5>"})
+.sometimes(x => x.lfo({dr: "4"},0))`}
+/>
+
+You can also name your lfos and refer to them by name, using the `id` parameter
+
+<MiniRepl
+  client:idle
+  tune={`
+s("saw").lfo({}, "lfo_freq_saw").lpf(800)
+.lfo({s: "<4 8 0.5>"}, "lfo_lpf")
+.sometimes(x => x.lfo({dr: "4"},"<lfo_lpf lfo_freq_saw>"))`}
+/>
+
+## FX index
+
+If you are using `FX()` to reorder your effects, you dont need to write your lfos inside the `FX`,
+but instead can refer to them by their FX index (starting with 0)
+
+<MiniRepl
+  client:idle
+  tune={`
+s("saw").FX(
+  distort(3),
+  gain(0.3), // this has the fx index 1
+  lpf(400)
+).lfo({s: 16, dr:2, c:"gain", fxi: 1})`}
+/>
+
+## Modulating other LFOs with Sub-control
+
+LFOs can modulate other lfos and will modulate their frequency (given by `r` or `s`):
+
+<MiniRepl
+  client:idle
+  tune={`
+s("saw").lpf(400).gain(0.8)
+  .lfo({s: 16, dr:2, c:"gain"})
+  .lfo({s: 0.3, dc:-1, dr: 0.8})`}
+/>
+To modulate other parameters of the first lfo (like `skew`, `depth` and so on), we can specify this with `subControl`or
+its alias `sc`
+
+<MiniRepl
+  client:idle
+  tune={`
+s("saw").lpf(400).gain(0.8)
+  .lfo({s: 4, dr:2, c:"gain"})
+.lfo({s: 0.3, sc: "skew"})`}
+/>

 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 _how_ this is done, only _what_ is to be done.

+layout: ../../layouts/MainLayout.astro

+
+# Helix Keybindings in the REPL
+
+The Strudel REPL supports [Helix editor](https://helix-editor.com/) keybindings through the `codemirror-helix` extension. Helix is a post-modern modal text editor with a focus on selection-first editing and multiple cursors.
+
+## Enabling Helix Mode
+
+1. Open the Settings panel in the REPL (click the settings icon or use the keyboard shortcut)
+2. Find the "Keybindings" section
+3. Select "Helix" from the available options
+
+## Key Differences from Vim
+
+Helix uses a selection-first approach, which means:
+
+- **Selection → Action** (Helix) vs **Action → Motion** (Vim)
+- For example, to delete a word in Helix: `w` (select word) → `d` (delete)
+- In Vim, it would be: `dw` (delete word)
+
+## Common Helix Commands
+
+### Normal Mode
+
+- `i` — Enter insert mode before selection
+- `a` — Enter insert mode after selection
+- `v` — Enter visual/select mode
+- `w` — Select next word
+- `e` — Select to end of word
+- `b` — Select previous word
+- `x` — Select/extend line
+- `d` — Delete selection
+- `c` — Change selection (delete and enter insert mode)
+- `y` — Yank (copy) selection
+- `p` — Paste after selection
+- `u` — Undo
+- `U` — Redo
+- `/` — Search
+- `n` — Select next search match
+- `N` — Select previous search match
+
+### Movement
+
+- `h, j, k, l` — Move left, down, up, right
+- `gg` — Go to start of document
+- `ge` — Go to end of document
+- `{` / `}` — Move to previous/next paragraph
+- `%` — Match bracket
+
+### Multi-cursor
+
+- `C` — Duplicate cursor to line below
+- `Alt-C` — Duplicate cursor to line above
+- `,` — Remove primary cursor
+- `Alt-,` — Remove all secondary cursors
+
+## Strudel-Specific Features
+
+Currently, Helix mode in Strudel provides standard Helix keybindings. Unlike Vim mode, there are no custom Strudel-specific commands (like `:w` to evaluate) yet.
+
+To evaluate code while in Helix mode, use the standard shortcuts:
+
+- `Ctrl+Enter` or `Alt+Enter` — Evaluate code
+- `Alt+.` — Stop playback
+
+## Resources
+
+- [Helix Documentation](https://docs.helix-editor.com/)
+- [Helix Keymap](https://docs.helix-editor.com/keymap.html)
+- [codemirror-helix on npm](https://www.npmjs.com/package/codemirror-helix)
+- [codemirror-helix on GitLab](https://gitlab.com/_rvidal/codemirror-helix)
+
+## Notes
+
+- The `codemirror-helix` extension is described as an "initial version" and may not implement all Helix features
+- Behavior may differ slightly from the native Helix editor
+- If you encounter issues, you can switch back to other keybinding modes in Settings
+- The keybinding preference is saved in your browser's local storage
+
+## Contributing
+
+If you'd like to add Strudel-specific Helix commands (similar to Vim's `:w` for evaluate), contributions are welcome! See the implementation in `/packages/codemirror/keybindings.mjs` for reference.

+- It's running [some code](https://github.com/patternclub/alpacalab/blob/main/course/main.py) that listens for messages using an "Internet of Things" network protocol (called MQTT). When it receives a message, it moves a motor.
+- It connects to a small server (running software called 'mosquitto') on Alex's laptop.
+- Strudel can send these messages instead of triggering sounds - that's how we use it to pattern movement.
+
+## First movement
+
+Let's get a motor running!
+
+1. Note the letter drawn on a label on the back of the microcontroller.
+
+2. Plug a battery into your microcontroller.
+
+3. Plug a motor into 'servo' (not motor) plug numbered 1, with the yellow (lightest) cable closest to the '1', and the brown (darkest) cable outward
+
+4. Run the below to set up some values, changing the `x` in 'robot('x')` to the letter on your microcontroller.
+
+<MiniRepl
+  client:visible
+  tune={`
+   $: move("-60 80").motor("0").robot('x');
+  `}
+/>
+
+<Box>
+
+If you refresh the page, you'll need to change the letter to match your robot again.
+
+If your motor starts moving unexpectedly, someone else might have put your letter in by mistake!
+
+Note that in the above, we start counting motors from '0', so motor 1 on the board is motor 0 in the code.
+
+</Box>
+
+## Patterning movement
+
+Many strudel features for playing with sound patterns will work when
+playing with motor patterns. Try playing with the mininotation in the
+`move` command:
+
+<MiniRepl
+  client:visible
+  tune={`
+$: move("-10 0 10 [20 30]*2").motor("0").slow(2).robot('x')
+  `}
+/>
+
+The move instructions are in the range from -90 to 90.
+
+<box>
+  If your motors stop working at some point, and your code looks right, try pressing the 'reset' button on the
+  microcontroller.
+</box>
+
+It's possible to make smooth movements based on different 'waveforms', for example a smooth sinewave:
+
+<MiniRepl
+  client:visible
+  tune={`
+$: move(sine.range(-30, 30).segment(16)).motor("0").slow(2).robot('x');
+  `}
+/>
+
+The movement is still quite jerky, because the 'segment' command is
+only taking 16 positions from the sinewave. Try increasing it to 32 or 64. It's best not too much higher than that, as the microcontroller
+might get overwhelmed with a backlog of instructions!
+
+<box>
+  Try replacing `sine` with other waveforms: `saw` (sawtooth wave), `tri` (triangular wave) are good, and there is also
+  `rand` (random wave) and `perlin` (a kind of smoothed-out randomness).
+</box>
+
+## Patterning more than one motor
+
+You can pattern the `motor` command separately from the `move` one:
+
+<MiniRepl
+  client:visible
+  tune={`
+$: move("-10 0 10 [20 30]*2").motor("0 1").slow(2).robot('x');
+  `}
+/>
+
+Alternatively, you can pattern two motors in separate patterns. The below sends the same pattern for the first two motors, but with the second one running slower:
+
+<MiniRepl
+  client:visible
+  tune={`
+
+$: move("-10 0 10 [20 30]\*2").motor("0").slow(2).robot('x');
+
+$: move("-10 0 10 [20 30]\*2").motor("1").slow(3).robot('x');
+
+`}
+/>
