Thanks. Those are the versions we both have - the problem existed before and after those updates. I followed all the instructions on the troubleshooting page - even so far as to only use exported stems for playback.
We’re both using headphones. When the drummer brings up the mic channel in the Performer monitor section, he says that he’s hearing his playing coming back to him delayed - enough that he can’t play if he’s got that fader up. This is when we are in idle mode with talkback enabled. (not recording or playing back the track)
We’ve tried this with both the current versions and the previous versions, and every single time, the recorded track is offset by exactly one 16th note - this behaviour is consistent.
One thing we haven’t tried as of yet is to import the stems to a fresh project. We’ll try that next.
