There are a way to use the standard Knobs and Buttons (For ex: Volume or Tone on EP Mode), to control the Zones?
In a simple words ..... I have a LIVE SET (MST and ADV activate) with just PIANO SW = ON, and two ZONEs sending message to my Roland Integra-7 (Midi Channel 2 and 3).
So, I'm trying to control the volume on my "External Module" using the CP73. Is it possible?
