Midi in

[felixroos]

allows using midi cc to control a mutable variable that itself is a pattern!

example:

let apc = await midin('APC MINI')
  
n(run(apc(54).range(1,12).round()))
  .chord("<Cm D>/8")
  .jux(rev)
  .offset(apc(55).range(-10,4).round())
  .voicing()
  .add(note(apc(48).range(0,12)))
  .lpf(apc(49).range(200,2000))
  .clip(apc(50).range(0.01,4))
  .room(apc(51).range(0,2))
  .delay(apc(52).range(0,1))
  .sometimesBy(apc(53), add(note(12)))
  .piano()

maybe note input would also be a good fit here

another, minimal example:

let cc = await midin('APC MINI')
s("hh*8").speed(cc(48).range(.5,1))

this will allow you midi device to control the hihat speed between .5 and 1

Is this still supposed to work I'm getting a bunch of JS errors in the console with the following code based on your minimal example (for an APC Mini MK2, but also for a custom controller):

let cc = await midin('APC mini mk2')
s("hh*8").speed(cc(48).range(.5,1))

EDIT: nevermind, seems to be an issue on Firefox Developer Edition
