Trying to figure out what overtone.live provides over overtone.core . Seems live attempts to boot and connect to the server but then I also see things with a mixer/instrument registration and that's where I can't really follow along so well.
Is there documentation on how/when SC buses/groups are created? First glance, it seems bound to the instrument but maybe I want FX to apply to groups of instruments. Maybe that's when I'd need to use some of the more lower level functions in Overtone beyond live?
I just created a https://github.com/overtone/overtone/pull/581 that you might be interested in. It adds functions to replace the default output mixer of all instruments in a studio. You could use this functionality to replace all the output mixers of instruments in group A with a synth that performs the effects of group A. Repeat for other groups of instruments.
