Hooked up the entire deal last nite with eight channels of my RME9652/Sonorus audio system fed into a patch bay directly beneath my dot.com modular. It's a little tricky to initially set up in Logic (because of the necessity of using aux outs in the mixer), but MOTU includes a little tutorial video that helps a whole bunch. All the gates, triggers and LFO's work swimmingly, but pitched oscillator stuff is a different story... Unfortunately, I can't get the oscillator pitch calibration function to work. The Volta plug-in refuses to see any incoming audio, which is vital for the calibration to work. And regardless of how in-tune the synth's oscillators are, Volta simply won't play anywhere near in tune unless you perform the calibration process. Boo hoo. I talked to MOTU tech support this morning, and they acknowledged that there are some known issues regrading audio routing when using non-MOTU audio intefaces, specifically related to the calibration function. They also say they're trying to address them (to their credit, there's already been two minor upgrades- Volta is at v2.0.1). As far as I can tell from friends and forums, it's looking more and more as if Volta is a MOTU audio interface-only  kind of beast. This weekend I'm taking a MOTU Ultralite home with me, so I'm crossing my fingers.
