Main stage midi mapping two sounds
So I purchased Mainstage a couple of days ago because I’m looking to play the sounds I’ve created in logic live. This hasn’t been a problem but I have run into another dilemma, I need to play two sounds at the same time during one song. To do this I’m hoping to have the midi keyboard play the Steinway Grand Piano patch but then have the midi pads (on said keyboard) mapped to play a certain note from my Rotor sound. Can I accomplish this and if so how?
