# Midi basics
USBSID-Pico supports (Web)Midi over USB that acts as Midi device that can receive Midi commands.

# Strudel.cc
_Excerpt from Strudel website_
[Getting Started](https://strudel.cc/workshop/getting-started/)
With Strudel, you can expressively write dynamic music pieces.
It is an official port of the [Tidal Cycles](https://tidalcycles.org/) pattern language to JavaScript.
You don’t need to know JavaScript or Tidal Cycles to make music with Strudel. This interactive tutorial will guide you through the basics of Strudel.
The best place to actually make music with Strudel is the [Strudel REPL](https://strudel.cc)
## Strudel and USBSID-Pico
With it's WebMidi support you can use USBSID-Pico directly from your browser with [Strudel.cc](https://strudel.cc)

# Notes
Strudel's WebMidi implementation isn't complete and still under development, see [this issue](https://github.com/tidalcycles/strudel/issues/192) for more information.
To overcome `progNum` not being available yet there is a workaround in the examples below.
Strudel has a drawback when it comes to `ccv` values. The 0~127 midi range is compressed/remapped to 0~1.

# Strudel Examples
Below are my personal notes and scribbles, if they don't work then they don't work.

## Prognum
Missing `progNum` workaround
```js
let progNum = register('progNum',
(prog, chan, pattern) => pattern.onTrigger(
() => WebMidi
.getOutputByName('USBSID-Pico')
.sendProgramChange(prog, chan)
)
)
```
## Init function
This function `.init()` wil make the bank 0 select only run once
```js
let init = register('init', (pat) => pat.filterWhen((begin) => begin<1))
$: ccn(0x20).ccv(0.0).midi('USBSID-Pico').init() // bank 0
```
## Individual Voice setup
If you want to use the SID voices directly you can use bank 0 and bank 1 for this.
To configure them use the examples below.
```js
// SID1 ~ Voice 1
$: stack(
ccn(0x20).ccv(0.01), // bank 1
ccn(0x1).ccv(0.5), // pwm start
ccn(0x7).ccv(1), // volume
ccn(0x6E).ccv(6), // set frequency cutoff @ 0xB0 (176) = 6 ~ 5,5 (0xFFF max mapped to 127 in steps of 0,03125)
ccn(0x71).ccv(0), // enable filter on voice 1 < bugged
ccn(0x6F).ccv(0.9), // set resonance on filter to 0xB (11) = (0xF max mapped to 127 in steps of 8)
ccn(0x77).ccv(0), // enable lowpas filter
ccn(0x78).ccv(0), // enable bandpass filter
ccn(0x79).ccv(0), // enable highpass filter
ccn(0x49).ccv(0), // attack
ccn(0x4b).ccv(0), // decay
ccn(0x40).ccv(1), // sustain

ccn(0x15).ccv(0), // noise
ccn(0x16).ccv(0), // pulse
ccn(0x17).ccv(1), // sawtooth
ccn(0x18).ccv(0) // triangle
// progNum(1) // not working yet
).midi('USBSID-Pico').midichan(1).init()
// SID1 ~ Voice 2
$: stack(
ccn(0x20).ccv(0.01), // bank 1
ccn(0x1).ccv(0), // pwm start
ccn(0x7).ccv(1), // volume
