Is this automation drift something that you have added to your list for a future update?
While it's not a huge issue, for most of my songs, there are a handful that have precise MIDI patch change events (such as Comfortably Numb- Pink Floyd) that switches my vocal delay patch on/off, during the first lines of the verses. My only option now, is to write down the event timing (of the original automation events that work well) and then adjust the timing back to where they belong after overdubbing new automation.
For this particular song, I noticed the drift being between .01 - .54, with most being > .17
This is quite a bit more than 1/100 of a second.
Thanks,
