Excerpt from Strudel website Getting Started With Strudel, you can expressively write dynamic music pieces. It is an official port of the Tidal Cycles 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
With it's WebMidi support you can use USBSID-Pico directly from your browser with Strudel.cc
Strudel's WebMidi implementation isn't complete and still under development, see this issue 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 0127 midi range is compressed/remapped to 01.
Below are my personal notes and scribbles, if they don't work then they don't work.
Missing progNum workaround
let progNum = register('progNum',
(prog, chan, pattern) => pattern.onTrigger(
() => WebMidi
.getOutputByName('USBSID-Pico')
.sendProgramChange(prog, chan)
)
)This function .init() wil make the bank 0 select only run once
let init = register('init', (pat) => pat.filterWhen((begin) => begin<1))
$: ccn(0x20).ccv(0.0).midi('USBSID-Pico').init() // bank 0 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.
// 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
