beige G3/466 MT AV, OS 9.22, 384 MB ram I run PT LE 5.21 on my Mac under OS9.22 just fine, using OMS for MIDI communication with my two MTPII's. Question: if I buy a new HD & put OSX on one partition can I run ProTools LE 6.1 with my 2 serial MIDI Timepice II's. I have no USB on my Mac & no PCI slots available either as my 3 PCI slots are full. Respond to me also at:
