Pitch shift corrupts audio, track now delays..Help!

Post by toodamnhip »

A strange new bug has devoped wherein after pitch shifting a take of audio, something gets corrupted such that that track alone ignores my 128 buffer play thru setting and passes audio thru very late, as if the buffers are at 1024 etc. I am talking about my guitar passing thru live for recording. What ever is recorded plays back fine..Just recording new audio becomes impossible because the audio passes through the comp with huge delays

Messing with the play back engine, trashing prefs, turning audio on and off, repair of permissions does no good.
It seems that THAT audio, inside that track only, now makes the track pass new audio thru late. All other tracks will pass audio thru fine.
One fix has been to consolidate the bad audio in the track in question, whch then creates new audio, removing the corrupted audio from the track and thus, allows the track to pass live audio thru back at the 128 rate once again.

Are you using Automatic Plug-in latency compensation?

It sounds like what happened to me when I forgot that.

Your audio track isn't becoming corrupted. Putting the pitch adjustment on the track is going to delay the audio. If you do this in playback, you won't hear it if the latency compensation is on because it will delay the other tracks to match. Merging the track is just applying the pitch adjustment and turning it off.

I can't figure out why you are recording to a track you've pitch adjusted. If you need to punch in on the track just disable the pitch adjustment and turn it back on after. Otherwise, just record to a new track and combine them after.

Hey man!

That might be a great idea, to turn off pitch untill I consolidate..
I will try it next time, if you are right, thank you sooo much...
I pitch while still recording to see if I can salvage pieces of a great take and how well I can do so...
