Thanks for the help. But I want to use the Casio as the master. For example , we play the song "Alone" by Heart. Right now using the FA keyboard split, I play the piano part on the left and a pad on the right. I want to build a patch with the Casio playing the piano only while it triggers the FA to play a better multi part pad with the sliders on the Casio handling the mix for both, stored as a studio set (Roland) and a Casio stage set for instant recall. And do the same for every song in the set. Some have said I need a laptop running mainstage or something similar but I want to avoid computers on stage.
