Due to my external monitoring setup set-up, I prefer using the auto monitoring in tapemachine mode. Monitoring is automatically turned on in stop and record, but automatically turned off on playback.
However, I would expect Export Mixdown to be equivalent to playback, and that the monitoring is disabled when performing a mixdown. This does not seem to happen. If I happen to have a track armed for recording when I do mixdown, this track will not be part of my mixdown. I cannot see how this could be the desired behaviour.
