I'm thinking about buying a RD300SX for gig work. I've studied the manual but it's not clear about whether one is able to set up batches of tones on each setup (of which there are 32 setups). I would like to be able to trigger these sounds from another midi keyboard by selecting different channels which will correspond to the channels that the tones on the rd300 have been setup on. If this is possible, then am I able to select any sound from the entire 400 odd sounds including allocating any of the GM2 sounds to any of the channels. Thanks in advance for any advice. Nick
