I work in a few groups and would like to find an easier way to control all the patch changes. I currently have a Korg Triton Extreme and an 01/W plus an ipad2... any recommendations on a software program I can download to the ipad2 that would accommodate this? And how I would hook up the keyboards (I'm assuming via some sort of interface, I have a Tascam US-144mkII....would that work?) thx!
