I've been involved with recordings now for a while... Now I want to invest in my own home studio. I'm trying to make the decision between software or an siab. If siab, then I'll get a Korg d1600mkII (or Tascam 2488) w/ Acid Pro 5 on the PC. Otherwise, I'll go with Sonar 4 Producer Edition... There's no question that Sonar can do a lot more than Acid Pro (IMO). And I'm going to invest a lot of time in learning the software in either case... My questions are, given my willingness to master either software... 1. does Sonar will offer a significantly better finished product (so far as sound quality is concerned)? 2. How are the mastering capabilities of Acid? I've noticed many more plug-ins and support available for Sonar, but I'm wandering do I really need it.
