ok so here are 6 pictures of a protools session in various states of operation.
the first it the session with transport stopped and the plugin in active.
the second is with the transport stopped and the plugin active
the third is with the transport stopped and the plugin bypassed notice no major difference between the bypassed and unbypassed plugin on the cpu meter.
fourth has the transport in playback and the plugin bypassed
fifth has the transport in playback and the plugin unbypassed. there is a very neglegible amount of cpu usage increase on this one. i beleve this is attributed to active information the gui displays on the screen. if you close the plugin dialog box the cpu returns to the same level as in the fourth picture (see picture six)
and for whatever its worths this is a 24 44.1 session with a 256 buffer on the interface and a level 2 dae playback buffer with 1 processor enabled. running on a dual g4 fw800 1.42 ghz with 1 gig ram. 002R interface.
