Not much of a music person, but are you saying that you are mixing 30 wav files together? If so, and they are good sized files, then I would say you need more ram. Which os are you using? I've heard that win98 doesn't utilize more that 128mb, so any more is a waste (anyone with more knowledge please correct me on the 128mb thing). I would guess that win2k with 256 megs would give you the best performance. Ram is VERY cheap right now. 128mb PC133 sticks of ram are going for under $50 currently. For $50, pick up a stick and see what happens. I believe it will speed things up for you.
