I use giga on a seperate pc, but sequence and mix on the Mac.
Giga runs on an RME digi96 card, which lightpipes to a Korg Oasys card on the Mac. This connects via spdif to my PT 24 setup (3 farms).
The PT24 setup has a 1622 and 2x882 for synth inputs; I mix entirely in Protools without a mixer, using a logic control as a control surface.
The good bit is that what you hear is what you get (no need to set levels when you record), and I can record midi parts by just soloing them and bouncing them in logic. I can also record all parts seperately at the same time.
Last but not least, you can apply TDM plugins to all the input channels if you want, meaning I can use a lexiverb on one channel and a MCDSP Analog channel on the other; since TDM does processing on the card there is no audible latency.
Downside is that there is no sound when I don\'t have logic or Protools running, since the mixchannels are created in software.
Anyway, I\'n not missing a hardware mixer one bit
Munsie, my signal path varies depending on the project, but generally like so:
Digital Performer 2.7 with MTP/AV USB ganged w/original MTP feeding original 2408. Clock from Genx6, 44.1, all clock cables exact same length.
Mixer is Mackie d8b feeding the Mackie HDR24/96 or direct back to DP, depending if I will have comp edits. (I keep the editing out of the Mac, it keeps the tracks less fragmented.)
Giga acts as a module-MIDI from DP to Giga, Gina output, usually S/PDIF to a Zsys Digital Detangler. This is a great piece of gear for those of us with digital mixers with ONE S/PDIF in/out and 5 or 6 pieces of digital audio gear to
contend for that port.
Generally my Giga tracks are played one at a time to DP, then mixed back to the same PC into Cool Edit. If it\'s a quick-and-dirty, I;ll run the Giga app AND Cool Edit, the Giga out to S/PDIF and right back into Cool Edit. Surprizingly, I have had almost NO crashes, and no glitches.
