Editing multiple MIDI tracks

Cubase

  1. Is there a way to edit/automatate multiple MIDI tracks at the same time.
  2. Is there a way to edit/automatate VOLUME on multiple MIDI tracks at the same time without using the faders with Q links. I’m looking for precise control.

Yes, there is. Volume of MIDI track is linked with MIDI CC7. You can Enable Record on more tracks at once, and use MIDI CC7 to automate it.
