Hey blue,good advice from midiroom about the motif rack.Couple things to think about with your controller choices;can you set up zones/splits? how many channels does it transmit on?before you buy,maybe have the salesman hook up what you want to buy-make sure how it works.for example,if you run multiple modules,you may have piano on one channel across the board,bass in another range,horns etc.will/do you want to layer sounds? also,certain control changes;vol ume i.e,if you move the slider wanting more or less on 1 layer-will effect all the others.one of our (older) boards,if you turn vol down or changesprograms effects the modules etc.not a big deal once you get used to it,but a few suprises have fun,be blessed
