-## What is a 'hap'?
-
-A 'hap' is a name for a thing that happens, e.g. `note("c3 -")` playing a note and then stopping after a while. Haps have a start and an end. Every separate sound that is produced by strudel is a hap on its own.
-
-We would have called it 'event' if this particular name wasn't used by JavaScript to describe things that happen on html pages, like clicking on a button or hovering over a line of text.
-
-Since strudel is written in JavaScript, this confusion of having the same name for different things is avoided by calling events 'haps'.

-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 to 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.
-

-The default value is 1. Writing numbers greater than one can make it more intense,

-Patterns are the essence of Uzu languages such as Strudel and 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.

-# Controlling motors with Strudel
-
-Strudel is mainly made for making music, but it's possible to pattern other things with it, including motors.
-
-We're going to use a microcontroller for this, called an "[Inventor 2040W](https://shop.pimoroni.com/products/inventor-2040-w)", which is
-a [Pico W](https://shop.pimoroni.com/products/inventor-2040-w?variant=40053063155795) with extra ports added including some for controlling motors.
-
-![image](https://shop.pimoroni.com/cdn/shop/products/Inventor2040_1of3_1500x1500_crop_center.jpg?v=1656927927)
-
-## Technical details
-
-Feel free to gloss over these!
-
-- The Inventor 2040W connects to the internet wirelessly, and it can power from a battery or USB. Hopefully the batteries last!
-- 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');
-
-`}
