I think this might be something we can expand to other use cases as well. I could add support for defining custom track groups that can be muted or soloed via OSC. Not sure about the exact syntax yet, but something like +GROUP-REF could work to add a track to a group called “ref”.
That way, you could define multiple groups, e.g. +GROUP-PADS, +GROUP-VOX, etc. that can all be muted or soloed.
What do you think?
