This is a utility for muting and unmuting Loopy tracks that also starts and pauses Loopy playback.
This is a simple example of using Mozaic to control Loopy and how to set up pads as toggles. Almost every aspect of Loopy can be controlled by MIDI.
For this to work, you will need to set up MIDI Bindings in Loopy for the commands used. Hopefully the logic is straightforward. If not, give me a holler.
