Well, LE wouldn't quite be up to a mix plus system, cause regardless of processing power, LE is limited to 24 tracks, but it would give a great boost as far as plugins are concerned.
How OS X works is when you launch a 9.x app, a version of 9.1 boots up inside OS X. When you run the 9.x programs they have the old menu bar and everything. That is what is called classic mode.
You can also boot entirely into 9.1, not involving OS X at all.
Unfortunately in OS X, the system can't find the hardware for ProTools. I have an digi001 at home, and if i want to use it, i need to reboot in 9.1
I haven't tried it with any of the TDM system, my boss won't let me bring my copy of OS X within 10 feet of any of the computers at work (he has a fear of change
), but I'm assuming it's probably the same situation.
Hopefully Digi will jump on the bandwagon soon.
