Hi, I just found syphon , and have little question. I am looking for a way to synchronize play of two instances of Garageband , What I got is that It is possible to invoke play on garageband through apple script but I need some kind of au plugin or rewire host that can do that. Is siphon doing something similar ? I am also prof developer of ios so maybe I can code something if I got some code example to start, I just want to play my music tracks life from multiple gb instances synchronized… Thank You.
