Documenatation for USB-MIDI as client?

[Dave Smith]

I have this working, in that the Xiao RP2040 shows up as a MIDI device.

I'm using this page to test: https://www.onlinemusictools.com/webmiditest/

But I'm lost from here, is there any documentation?

package main

import (

   "machine"

   "machine/usb"

)

func init() {

   machine.EnableMIDI(midiTx, midiRx, midiSetup)

}

func main() {

}

func midiRx(bs []byte) {

}

func midiTx() {

}

func midiSetup(sup usb.Setup) bool {

   return true

}
