I am struggling to record MIDI data. Let me explain.
I have a song. I press Command M to map the volume of to a fader on my USB MIDI Controller. MIDI Assigns successfully! Record MIDI Mapped Parameters to Automation is checked. I slide the fader, the volume of my track changes. Great success! I enable edit mode by pressing escape. I play the pattern. I move the fader. The volume of the track changes while the song is playing, but no automation data is written, either in the pattern or in the automation section.
