Getting clip info

[jonathan3692bf]

Hi,

First of all, thanks for your incredible work! I’m having a hard time figuring out where/how I can add event listeners to clips for a given song. Could you please point me to some documentation on how to access each name spaces’ observable traits?

E.g. I see that if I want Song-View traits, I need to go through ableton.song.view.addEventListener. How do I do the same for all the clips loaded up?

Hey @jonathan3692bf,

Observing a value on all clips isn't trivial since you need to manually add the event listener to each clip in your session. In arrangement view, a basic solution that just covers the first track might look like this:

const tracks = await ableton.song.get("tracks");
const clips = await tracks[0].get("arrangement_clips");

for(const clip of clips) {
  await clip.addListener("name", (name) => console.log("New name:", name))
}

For session view, it would look like this:

const tracks = await ableton.song.get("tracks");
const clipSlots = await tracks[0].get("clip_slots");

for (const clipSlot of clipSlots) {
  const clip = await clipSlot.get("clip"); // might be null if the slot is empty
  await clip?.addListener("name", (name) => console.log("New name:", name));
}

This only adds listeners to the current clips though, so you'd have to add an event listener to the track for arrangement_clips or clip_slots and make sure that new clips get a listener as well.

I hope this helps!

Thanks for this; I arrived at something similar. I'll post it shortly.
