Default Delay Compensation bug in PT11 with AOS plug-ins (fixed in PT 11.2.1)

Hey,

I'm a new and yet unexperienced PT user here. Been using PT10 for half a year or so. Since a lot of 3rd party plugin developers have updated to AAX 64, I'm now testing PT11.

I noticed a different behavior in delay compensating aux inputs, coming from a multiple output instrument plugin.

In this case I have an instrument track with an instance of Addictive drums.
I am routing the snare to two aux inputs for individual treatment (e.g. additional triggering).

No matter what delay compensation setting I choose, I get non aligned audio when adding a plug-in to one of the aux tracks.

Please check this quick video:

I used an instance of Waves C4 just for the test. In PT10 this all went flawless.
Please help me understand how to deal with this in PT11.

Thanks a lot!
Erwin

I'd call that a bug. It can be reported here.

Hoping for a quick solution because this way PT11 is unusable for me as well as others, I guess...

using multi output/buses/hardware/inserts/DSP/Native plug-ins in a session with Strike 2.0 or Superior Drummer 2.0 it's pretty easy to reproduce this bug.
Avid needs to address this bug ASAP!

Just so I understand what's happening here...

ADC is not working when routing an instrument's multi-out to a bus, and inserting a plug-in on said bus?

And it works fine if the bus is empty?

Yes.

It is most obvious when you duplicate an aux, using the same multi out source as an input, and then adding an insert to just one of the aux tracks. The result will be the typical phase shifted sound, as demonstrated in the video.

I am not sure if this happens also when the source is just a regular audio track, instead of an instrument's multi out.

I am gonne install 11.03 on my home Mavericks machine to see if it's solved.

Will report back here...

So printing the tracks still works without ADC problems, then?

Not sure what you mean mesaone.
Aux tracks can't be recorded onto, right?

Avid should first fix the major bugs and then start to give the 90 day free tech support. ...

Related issue here (HD 11.0.3 on HD Native).

My instrument tracks having plugins do not compensate for delay, while my audio tracks do.
The second I disable an instrument plugin on the instrument track, delay compensation turns on.

Can anyone confirm this behaviour?

If this is a feature instead of a bug, then I am having a hard time understanding it.

As a side note: In another project on PT11 I had track displaying a compensation of some 1000 samples (I think 1032 but not sure), while there wasn't any track displaying this amount of latency! After changing buffer etc. it just went away.
There is something going on here for sure.

Edit: Found the source of the "Ghost" delay. An instrument track was routed to an audio track's input, which caused the long delay. I have no idea why that is, but it can be reproduced by simply routing an instrument track to an audio tracks input (which I regularly use when "track freezing" eg. bouncing).

Avid, I (we?) would love to have some documentation of what exactly goes on in PT11 regarding track delay compensation and plugin delay compensation, because I have no clue whatsoever.
