Hello,
I was running some tests with my VST plugins to see what type of coloration they place on a track, simply by instantiating them in Pro Tools 11. I created 2 audio tracks with Patchwork on each. Then, I placed my preferred EQ plugin on each instance of Patchwork. Both were zeroed completely, and phase reversed the first track... The audio ceased to play, which was expected.
However, if I 'bypassed' the Patchwork plugin on the second track, I still didn't hear any audio.... In comparison, I completely removed the Patchwork plugin from the second track, and began to hear audio... Which told me that indeed the EQ plug was causing some coloration.
So my concern is that, if I place a Patchwork plug on a track Bypassed, with a plugin within it, it seems that it's not truly bypassed.... Maybe it's just 'zeroing' the EQ plugins settings... Any thoughts on this? Thanks!
Patchwork true Bypass??

Which would indicate that Patchworks containing the EQ zeroed, does the same as Patchworks containing the EQ bypassed.ibanman555 wrote:However, if I 'bypassed' the Patchwork plugin on the second track, I still didn't hear any audio....
So the zeroed plugin could have no colouration when zeroed.

Or it could tell you that the phase (ie latency) difference between having the zeroed plugin inside Patchworks versus no plugin at all was enough to prevent nulling with another copy of the zeroed plugin inside Patchworks.
I think you need to check your conditions more exhaustively to know. For example try nulling a track with an empty Patchworks against a track without Patchworks; that would (dis)prove my alternate explanation.

Valid point there... I didn't take the latency into consideration... I'll test more...

The PatchWork plug-in is actually using a true bypass, and as required by the AAX format, it will report the same latency when bypassed and not bypassed and will include latency compensation on the bypassed signal.
However I would not be surprised if the plug-in you are talking about is altering phase even when zeroed - it is common with analog-stye EQs. This could explain this behavior.
