Grid for Keygroup Programs, MIDI Programs, and Plugin Programs
When a Keygroup Progam, MIDI Program, or Plugin Program is selected, the grid looks like this:
The only difference from the Drum Program view is the vertical miniature keyboard ("piano roll") in the left
grid window section. Click a key to select all note events for that note. You will also hear the note
assigned to that key.
Everything else works exactly as in a Drum Program.
