Midi Mappings - how to use midi object

Kia ora team!

Wondering if there’s any documentation on using the midi object in a custom script for midi mappings?

I’d like to create a script that uses OSC to get the song name along with bar and beat number, and if they match a certain value, then on a certain midi note send another OSC command - currently unsure where to find the right documentation about the using the “midi object to get midi data”.

I realise I could invert my logic and map a script to a note that will only execute when xyz condition is met via OSC values, but still curious about the above :slightly_smiling_face:

Hey @zacjohnsnz,

To see what the midi object contains, you can add a log(midi) command to the script. This will log all incoming MIDI data so you can see what you’re working with.

For example, when a Note On event is received, you get the following data:

{
  "type": "note-on", 
  "channel": 16, 
  "raw": [159, 38, 99], 
  "note": 38, 
  "velocity": 99, 
  "input": "Oakboard Floor Vista"
}

With this data in mind, you could do something like:

if (midi.type === "note-on" && midi.note === 38 && velocity > 100) {
  sendOsc("/global/stop")
}

You can make use of the code editor’s autocomplete functions to see what properties are available.

Let me know if this helps! :slight_smile:
