Trying to control Macros on Ableton via AbletonJS

[vanTesselhof]

Hey, I was wondering if you know if it's possible to configure/control macros via AbletonJS.
I tried to go to a macro via a selected track but couldn't find any solution.
Do you or someone know if it's possible?
Thank you!

Hey @vanTesselhof,

I just took a look at the unofficial API docs but couldn't find any way to control macros using the Python API. I'm sure there must be a way though as I've seen some MIDI controllers automatically map to macros in Live 🤔

Hi @vanTesselhof, I'm may have the same need but I'm not sure of yours.

What do you want to achieve ?
1 - map a parameter from another device to a macro ?
OR
2 - set the macro knob value ?

@leolabs : In the second case, maybe it could be on the device side rather than the rackdevice itself. What do you think of that idea ?

Hey @vanTesselhof and @paulmacmillan,

I think I just found a way to access macros of a rack, I was just looking for the wrong name. Here's a script that logs all parameters of the first device of the first track:

const tracks = await ableton.song.get("tracks");
const devices = await tracks[0].get("devices");
const params = await devices[0].get("parameters");
console.log("Params:", params.map((p) => p.raw));

This is what the output looks like:

    is_quantized: true

  {
    id: 'live_13735816264',
    name: 'Macro 13',
    value: 0,
    is_quantized: false
  },
  {
    id: 'live_13735816864',
    name: 'Macro 14',
    value: 0,
    is_quantized: false
  },
  {
    id: 'live_13735816704',
    name: 'Macro 15',
    value: 0,
    is_quantized: false
  },
  {
    id: 'live_13735816504',
    name: 'Macro 16',
    value: 0,
    is_quantized: false
  },
  {
    id: 'live_13735816584',
    name: 'Chain Selector',
    value: 0,
    is_quantized: false
  }
]

And each parameter's value can be set as well:

await params[2].set("value", 50);

Hope this helps!
