I've had the chance to spend a few days working with PT 9 on Mac. Other than ADC I didn't notice any advantage. More busses just seem to clutter my I/O options. But the real reason is price. I do mostly post production and I own DV toolkit. What I've noticed is that automation snapshots are only in lncluded with CPTK. This meas I need to spend about 600 (8 to 9 and DVTK to CPTK) just to get the basic fetuses I already paid 1300 for. Yes, I get surround but I don't need it. I appreciate how smart Avid marketing is but time and time again they seem too smart for their own good. Last week I worked in a studio that still uses a G5 HD just because of the pci HD cards. They spent a ton on surround monitoring and HD video gear but they refuse to pay the ridiculous premiums Avid want for the simple upgrade. Lead engeneer in that facility said the mix still sounds great on 7.4 so why upgrade if it costs so much?
