A basic patch that enables you to play more than one note at a time controlling Geoshred instruments via MIDIGuitar 2. It’s early days and I’ve uploaded a stripped down version of the one that I’m working on as I can’t get pitchbend to work nicely yet. I also had trouble when implementing variable polyphony so it’s set in the script at 4 voices but you can change that by adjusting the ‘poly’ variable in the first function…

Basically load this into Mozaic, point MIDIGuitar at it with polphon enabled, then map / mask instances of geoshred with you preferred instrument(s) to MIDI channels controlled by the Mozaic instance, starting at channel 2…
