I tried to do this per the documentation which says:
- Change the meter in first bar to cover the duration of notes.
- Change meter in second bar to meter of song.
- Click on 1st bar meter and check Pickup Bar in dialog box.
What happens is that all notes are displaced by the difference in the first bar meter change and they never move back when Pickup Bar is selected. Also, this resets all clefs in the song. I tried moving the MIDI Part start positions to be at the point of the first pickup note instead of the beginning of the measure(thinking that the rests would not be counted in Score), but that didn’t help. It’s like the pickup bar is keeping the rests, even when Pickup Bar is checked in the diaglog box.
