MIDI in/out

This extension lets you send and receive the following standard midi messages:

• note on
• note off
• control change

Wiring output

Connect to a 5pin midi connector like this:

Wiring input

the same wiring works for input in most situations, but if you want to follow the MIDI spec the input should have galvanic isolation by using an optocuopler like this:

Basic usage

//Set the midi in and midi out pins
midiInOut.setMidiInPin(SerialPin.P0)
midiInOut.setMidiOutPin(SerialPin.P1)

//Send notes (note number, velocity, duration, midi channel)
midiInOut.sendNote(45,127,100,1)

// Act on incoming MIDI messages
midiInOut.onReceiveNoteOn(function (channel, noteNumber, velocity) {
    basic.showNumber(noteNumber)
})
