some of these bugs I cant even produce.
-nudge in the PRV
I do a lot of nudging. but I nudge clips, not notes. but that's how different people work so im not knocking you.
-double clicking on a drum mapped mid file not centered
didn't even try it /
-loading track templates can sometimes wipe out your existing drum maps.
I've never had this happen and I have many different drum maps (session drummer, EZ Drummer, AD drums/ some I have multiple maps for each one.
-Undo system being unreliable
I haven't seen that either (showing the history of 10000 deleted envelopes)
sorry man.
they are probably just quirks that arise once in a while.
those aren't really bugs. they are just things that happen in an imperfect world.
