I created a short MIDI sequence using EZdrummer2 plugin and opened it in the piano roll. In one or two places I noticed Logic was adding additional MIDI hits which were invisible in the piano roll and didn't show up in the events list. I exported the sequence as a mid. file and imported into Reaper where I could then see the extra MIDI events. I edited out the notes and saved it. Upon re-importing to Logic, the invisible notes are still there! Can anyone explain?
