no doubt...

I've checked on two different systems so far and the control-command click fixes the delay issue perfectly but only when the VI is on an Audio track, NOT when it's on an instrument track.

I still can't figure out why this isn't being spread across those threads related to this specific bug. And if we can fix the delay comp issue with three presses of our hand why has it taken Avid over a year to write it into their code?

On the instrument/audio track, force enable delay compensation by control+command clicking the 'cmp' indicator. It should turn blue.

I've tested this for sync against an audio track (in fact by placing the same click sample on an audio track, phase reversing it and then playing it back with the sample from, in this case, Battery.

They cancel down to about -60dB (which is not as good as PT10, which used to cancel down to the noise floor of the dithered mixer (-138dB)), but the cancellation is consistent regardless of the delay caused by plugins on the aux tracks (across my 8 stereo auxes I used a various numbers of Maxims and Equilibrium (all bands bypassed) in FIR mode with an IR length of 16384- that produces a considerable delay!, but which is still within the compensation range of the delay comp engine.

The technique also works with VEP, which is where I run all my VIs usually.

I havn't been able to make this work with instrument tracks. At all.

See if it works for you.

Default Re: Delay Compensation bug in PT11 with AOS plug-ins

One question on this regarding Maschine / Geist - if you put Maschine on an instrument track then the internal metronome of Maschine (and hence the sequencer in Maschine) and the metronome in Pro Tools will not be in sync if there are high latency plugins on other tracks. You can fix this by putting Maschine on an audio track and doing the control+command trick. However, this also means you cannot play the pads in realtime into Maschine because there will be a significant lag. Also happens when trying to use a MIDI controller with Geist. However, this did not exist in PT10 and doesn't seem to exist with Boom.

Any ideas? Does PT have some sort of low latency mode like Logic that disables high latency plugins when a track is record enabled? The "Low Latency Monitoring" option doesn't seem to do the trick.

Eric, my tests also detailed that using instrument tracks is broken too, so the info is out there!

hopefully i'm stating this correctly…PT11 does have 2 modes of buffering…record buffer is whatever you set your playback engine buffer to…playback buffer is 1024 for 44.1/48k sessions and 2048 for 88.2/96k and above. but if you have high latency plugins inserted then you are tied to the impact/effect of that latency. so playback engine buffer plus latency of plugins inserted on that record-enabled track will be your bottom line when recording...

yes…and for those that wanna use INST trax then the workaround is manually inputing the total value of delay (from the delay field) of the plugins on the track as a negative value in the +/- user offset field...

I reported this to Avid in September of 2013 8 months is not enough time?
This video was posted 5 months ago https://www.youtube.com/watch?v=h7hZ...ZKhBEVm1WEzV4Q
I posted this very thread 8 months ago....
not enough time? ......
I think this not acceptable what is going on the Beta Testers in Daly City maybe all the fog there is too much smoke coming from the Avid building?

Default Delay Compensation bug in PT11 with AOS plug-ins

Well when they saw it and paid attention to it is another matter

Then a few meetings go by and they decide what to do about it then they release recourses to fix it.
