PPC quad and number of RTAS processors
 

Hello dear DUC,

I'm having some issues with my workstation theses days, i fell i'm not getting enough power out of it. I'm currently working on a digi002 on a PPC quad 2.5 with 4 gigs of ram, osx 10.3.9, pt 7.3.1, and i use a separate disc for recording audio, sata at 10'000 rpms.

I'm working on some sessions for a rock band, 10 mic drums, 2 guitars, bass, vocals and a bunch of overdubs. My sessions hold about 20 comps/gates, 20 eqs, 2 amplitubes and 2 reverbs. It's almost impossible for me to run the session, well it runs, but if i open a plugin a to change a control value my session crashes telling me i need more H/W buffer.

I tried to mess around with the Playback engine settings, and generally the best results are when using 1 RTAS proc at 99% with 1024 buffer size which i find VERY strange, I can't see what's using the 3 other prcessors. I also noticed moving the DAE buffer to anything but 2 (default) reduces system performances.

Cany anyone tell me what might help my performances?!?

I work in a studio equipped with a PPC 2x2.5 and they run sessions with a lot more tracks and plugs than me and it seems to run extremely fluidly... why?!? ok they use Digital Performer, but i doubt that's the issue, or at least refuse to believe =)

please help

10.4 is the minimum qualified OS for PT 7.

"Mac OS X 10.4 Required for all versions of Pro Tools 7 on Mac OS X. Pro Tools 7 will not run on Mac OS X 10.3.9 (Panther) and earlier."

Has it been working before this with that OS and PT version?

He might be mistaken - the Quad was introduced after the release of 10.4, the first Quads shipped with 10.4.2. I don't even know if any 10.3 version will run on a Quad...

indeed sorry, 10.4.3 is my current OSX version
