Yeah!
That's why I stated about converting the WAV's to MP3 format when I finish with song... Those WAV's take up alot of SPACE! ... as you correctly state!

P.S. I have 320 gig hard drive space in my main PC ( one 120gig and 2 100 gig hard drives) ... so space is not a problem for me yet!

UD is that your Main Music program at the moment ... anything else good that you use... or helpful insights into Acid Pro 4?
