Okay, I've been playing around with different music editing programs, and so far i like Sony Acid the best. The problem is that I want to be able to record my own samples, but I don't have the money or space for a full keyboard or synthesizer or anything like that. That's why my request is going to be a bit weird. Is there a music program that lets me map different sounds to the different keys on my computer's keyboard so I can still do real-time sort of stuff?
