The inline editor is more useful than it gets credit for, so I am pleased to see the new video
The In-Line MIDI Editor in REAPER.
I would just like to correct one mistake in the video: you don't have to open the main MIDI editor to add or change the inline editor's CC lanes -- simply right-click on the lane divider in the inline editor, and the CC selection menu will pop up (same as in the main MIDI editor).
