I just purchased a Dx5 for $50.00. I see that it sold new at $3500.00 (15 years ago). I was wondering what kind of a deal that was? My question is this: I have a new mac G4 and I want to incorporate that into my music experience. What would be the best solution as far as an inexpensive midi setup-and software- the bottom line is CHEAP. Just something to get me started. I'm reading thru the dx5 manual and I am finding I have a lot of learning to do. I want to eventually move to pro-tools but one thing at a time. Any info would be great. - thanks
