Is there a way to discover devices in device racks with the Live API?
If I make a call to the live API asking for a count of all devices in a track and then iterate over those devices:
live_set tracks 0 devices X
It seems to skip over devices that are in instrument/drum/effects racks. How can I access devices in racks with the API?
Unfortunately it's not possible at present.
I haven't tried yet, but should I assume the same issue applies to grouped tracks? or can you discover tracks within a group? What about the group itself?
No, the issue doesn't apply to grouped tracks. In my experience, group tracks and tracks within a group can be accessed basically like regular tracks.
