I've been studying the forums and the digi compatibility docs, and I can't quite figure this out... If I'm going to run ProTools LE (version 6) using the Mbox for audio I/O, are there restrictions on the MIDI interface I can use? (I know that digidesign is rather picky about what hardware is required for their software). Specifically, I want to use my desktop (dual G4/450) making MIDI additions to audio trax -- this box is currently set up with a DELTA 1010 audio/midi interface. So if I want to run ProTools on it, I'll need to put the Mbox on the desktop. But will Protools then let me select the Delta 1010 as the MIDI interface, or do I need some other "digi-approved" midi interface? (Meanwhile, for primary audio instrument tracking as opposed to editing, the plan is to use the Mbox with my Powerbook G4. For that, from what I'm reading, I think I should be able to generate a click track from within protools and hear it WITHOUT any MIDI interface or controller on the powerbook -- is that right, or do I also need to invest in some sort of USB MIDI interface for the powerbook, too?) thanks for any advice, david David F.
