I’m a newbie here, but not to Cubase. I’m a home recording enthusiast and songwriter - one man show now. Used VST, then LE until CS4 and then CS5. I have been using CS5.1.1 with the iMac, Firestudio, and a few plugins. It all functions very well with extremely few glitches, if any. I have not updated to 5.5.2 or now 5.5.3 yet. I like the idea of more instruments and sounds and VariAudio if I upgraded to C6, but I have to move up to Snow Leopard as well. Feeling a little nervous about potentially screwing up what already works on my system…shall I jump? Any opinions about all this would be most appreciated.
