Thanks for clearing this up David, I too was searching got the "show selected regions" option.
The manual also says
"The Piano Roll Editor can simultaneously display the contents of all MIDI regions in a
folder, all regions in a project, or several selected MIDI regions. "
Is there a way to show all regions in a project without 1st selecting them in the arrange page?
I would like a linked piano roll editor always showing all midi notes at that point in the song.
Thanks
