I was in the Piano Editor for one region and copied some notes to paste into another region. The playhead was in the right place, the Piano Editor was open to the right destination region and selected so it's highlighted and pressing CmdV pastes another region.
Why, in God's name, does every other Apple program paste with CmdV but in Logic you have to do Cmd-Shift V for 'paste in place'.
Thanks both of you. Eli, that's the first thing I thought of and I did it 4 times. I made SURE the Piano Editor was 'active'. I had added notes to a region and wanted to add them to its 'twin'.
Another oddity I ran into was when I 'OptionDrag' copied a region and it made about 8 copies of it pasted end-to-end - all in one region. Each 'copy' was dimmed, yet I had to cut them apart from the non-dimmed one before I could delete them. I then 'OptionDrag' copied other regions with no problem only to return to the problematic one and it did it again.
The manual says: "To set the MIDI Channel
Choose a channel number from the View > Hyper Draw > Channel submenu.
The chosen channel number is also displayed alongside the event type."
Yep. Did that, but it still controls all three notes.
