Lets say I have the waves masters bundle on the master Track FX to hear how it would sound all compressed....

Those take up alot of CPU, so I un-check them during editing. Are those plugins now disable, NOT eating up CPU, even when audio is being played??

I would hope so.

lol

I believe that whether or not the plugins are bypassed, the audio still has to run through the plugin. Therefore it uses just as much CPU to bypass as it does to have them enabled. Otherwise they would have to Load and Unload the plugin each time making the realtime aspect of playback and functionality compromised.

I was always under the impression that if no audio was running through a plug, or it was bypassed using the checkbox then it didn't take up as much CPU power - sure, it still takes up a tiny bit of memory, but think of un-checking those boxes as unpluging the input to the plug and putting it straight into the next plugin. It's basically like an invisble routing behind the scenes in Acid. Is this correct, SoFo?

Mike - Peter would be able to answer this, but unless something has changed, there is no difference in CPU usage when a plugin is bypassed.

I verified this...

We still stream through the plugins when bypassed or silence is being streamed.

Why? So that un-bypass is seemless. Some plugins are what are called "non-inplace" If we didn't stream through them during a bypass, the audio produced by them would be out of sync. The other alternative would be to stop/start playback on a bypass. We didn't want to do this.

Sorry for my mis-information back there guys :( I try....

Is it the case that when there is no event on a track the plug-ins don't take up any CPU power. Eg four bars of events, two bars without events then another four bars with events - is CPU power tied-up in the blank two bars?

Cheers,
