Okay, fellow MR musicians, I'd like some opinions/recommendations on DAW software that runs on OS X. A detailed explanation of my situation follows (those who don't want this, skip to the "tl;dr" part further below)... So here's my current setup: iMac (late 2010 Core i3), running Snow Leopard and XP via Boot Camp. Audio interface: Tascam US-122 (USB). Current DAW: Cakewalk Sonar 5 Producer, running in Boot Camp. Other external gear: M-Audio 02 and Korg MicroKey-37 USB controllers Roland SH-201 synth (connected via USB) Roland XP-10 and JV-880, Yamaha AN-200 synths/modules via MIDI-to-USB interface Yamaha DD-50 drum pad used for MIDI input, via MIDI-to-USB Roland TR-505 drum machine, not yet connected to my main rig, but would be via MIDI-to-USB if it were Even though I have several hundred dollars invested in Sonar at this point (I bought Sonar 4 Studio, then upgraded to 5 Producer), I'm considering a switch to OS X-based DAW software because of the inconvenience of switching to Boot Camp. Sonar 5 does not run well (or at all) in Vista or Windows 7, so that limits me to Snow Leopard in order to keep XP in Boot Camp, and Sonar is the only reason I use Boot Camp at all. This setup will soon start to become a liability, as more and more applications now require Lion or later, and this will become worse when Mavericks is released. I've played around with GarageBand, but find it only marginally useful as a "sketchpad" due to its extremely limited MIDI implementation and its consequential inability to use my external synths as sound sources. As a hobbyist electronic/synthpop musician, these limitations make it impossible to use GB as my main environment. I'm sure I could get used to another DAW, but I really like using my external synth gear and Cakewalk's Instrument Definitions feature allows me to browse patches on my external synths by name rather than just MIDI bank/program number. TL;DR summary: I'm looking for a OS X-based DAW that's comparable to or better than Cakewalk SONAR Producer, that plays well with external synths and modules. Snow Leopard compatibility is a plus. Comments and recommendations are greatly appreciated.
