I have a MOTIF RACK ES which i have used as a sound module for logic pro x. Now i wish to use it for my live gig. so i was wondering if there was any way to trigger patch changes from an external midi like the launchpad for example. I need to press a pad (in the midi controller) and must be able to change the patch in motif. This way i can assign multiple patches to different pads to recall them in a live performance. so far from my knowledge there are 3 messages - MSB, LSB and PC needed to change a patch and i have noted all the values i need from the manual. I do not know how to assign a key or button in my controller (running in logic pro) to send these values (msg,lsb,pc) to my motif rack es.
