Control Yamaha CP73 or CP88 from Logic/Mainstage


Recommended Posts

Hi all,
I've started creating a Scripter script to control my CP73 from Logic and MainStage. Sharing it here for any other CP owners who would like to do the same.

At the moment it just turns on/off sections and allows you to select voices for each section. I plan to add more functionality in near future, so will post an update with newer versions 🙂
