yes, I would like to see something similar for tracks as well as pages. Maybe a hardcoded map of MIDI note to page or track triggering, then you could use an internal MIDI channel within a track to trigger other tracks.
This could be a real nightmare though, keeping the mapping straight for so many tracks and pages.
What about choosing a master control channel, and then use a specific note that isn’t really used much in practice, like C0. then the velocity of this note is the value used to identify which page to trigger. Maybe restricting the trigger to only the active page in a row (0-9) and then the specific track to trigger would be the 1’s value of the velocity.
So, velocity 09 would to trigger track 9 of active page in row 0.
