Cakewalk Music Creator Pro. It's not too bad. While I'm still learning I'm going for ease of operation. What I need to find is the most reliable way to connect them. The soundcard I have on the way (M-Audio 20??) has 1/4, analog L/R, midi, and a small connect like a small printer port. Once I can transfer my Fruity Loops tracks to my Roland and a raw product back to the PC for mastering I should be set. The only rack thing I got is an ADA mp-1 tube preamp but it does it's job well.
