I've always kept my energy saver set to "Never" for sleep mode, but I could still put the computer to sleep by selecting it from the Apple drop-down menu. That's what I always did instead of shutting down. But now, it won't let me do that. Are you saying this is a normal consequence of Pro Tools? [since I never used Sleep mode in OS9, I never ran into this problem with PT 5.x.x]
I'm not sure if this problem is just an OS X problem, I know the bloat of OS X has had people with macs ranging from ANY powermac with PCI based graphics to the 733Mhz QS (with 1.5Gb RAM no less) suddenly end up with a slow, unworkable system. It seems Quartz bogs down Protools to the point where it's hell to work with or just plain unsupported in the case of the PCI macs.
I
am talking about LE here though, TDM is probably fine.
The
Digidesign User Conference has a hell of a lot of info from people who've already recieved their upgrades.
We ocassionally do a benchmark called the Dave C test, it gauges how fast our systems perform when recording to as many audio tracks as possible with a selection of 5 plug-ins on each track. If a system can record to all available audio tracks and still not put the cpu meter in the red, aux tracks are added with 5 plug-ins until it does.
It seems to be a total mixed bag of results. A dual 500Mhz G4 with 1Gb of RAM and a dedicated internal audio drive performed almost 72% faster with PT LE 6 under OS X and could use 95 plug-ins. Someone with a Dual 1Ghz G4 recording to the system drive (bad idea whatever DAW you use) only managed 120 plug-ins.
To judge what the stats actually mean to realworld performance you'd have to run some pretty heavy sessions before the macs themselves would start bogging down. Sadly, for comparison recent Athlon XP and Pentium 4 systems have been running anything from 170 to over 240 plug-ins in the same test.
I'm staying with OS 9 till we get some major hardware (PPC970 or 1.8Ghz G4s with DDR would be nice), I can at least USE my mac with PT 5 and I don't need to find alternatives to software synths that might not even work with PT 6.0 until they bring out PT 6.1 with rewire support later in the year.
