Re: some Qs about PT
I quick test non-scientific for some of the plug-ins I generally use in
PT 7.1cs4. I'll try again under 6.9, which would be closer to your enventual 6.4.1 system when I've got a moment. I don't have an Accel card, so the numbers are based on the instance per chip given by dutchmuzik on the DUC http://duc.digidesign.com/showflat.p...ev=#Post860557 or in the product manuals. I based it on the plug-in count per card (not chip) vs RTAS running approx @80-90% . To make sure the RTAS load wasn't crippling the system I tried recording a bit of audio, then playback. The playback engine was 96 voices, using 2 cpus and cpu usage at 90%, 48khz, 24bit. All tracks are mono. Sony oxford eq +filters process card 18 /accel card 46 /dual 246 180 @ 80%cpu MCDSP filterbank E6 process card 81/ accel card 144/ dual 246 355 @ 80%cpu McDSP Compreessor Bank CB3 process card 27/ accel card 69/ dual 246 220 @ 90%cpu Analog Ch 2 process card 81/ accel card 144/ dual 246 355 @ 80%cpu D-verb process card 36/ accel card 38/ dual 246 60 @ 90%cpu Digidesign Dynamics III comp/limit process card 63/accel card 162/ dual 246 140 @ 90%cpu Mod delay II extra long process card 18/ accel card 36/ dual 246 380 @ 80%cpu There are some real gains in efficiency when using multishell TDM plug-ins, as PT allocates then more effectively. For example the Sony Oxford eq/filters uses about 80% of a chip for two instances, leaving 20% that could be shared with other plugs. RTAS plug-ins instantiate much quicker than TDM after the first instance. |
