I have done several searches here and on Google and I am still completely confused. The situation is I have been playing a little bit with two people that and we want to get some live shows with my guitarist friend and a drummer. A lot of their music has parts that we don't have musicians for - keyboard, sound effects, violin, etc and we don't want to add anymore members for logistics reasons. Finding time to practice with five people is hard enough and we'd have to find a decent keyboard player. So what would be the easiest way to play sample parts on stage? Off the top of my head I'd be great if I could 1. Hit a button at the top of a song and it would play a keyboard part 2. Hit a couple different buttons on the start of each measure in some verses to play some different effects. 3. Play a whoosh sound at the end of a song. I know this is possible but I need someone to really dumb down what I need to do. I know I need a midi footswitch, if I get one with only 4 buttons could I program it so if I turn some knob or something the buttons change what they do? It would be great if I could keep this on the cheap too.
