Hello Timo,
Thanks for your comment.
I read official documentation and I understand very well how PERFORMANCE is controlled via CC (as described in my post).
It is not my fist experience with MIDI programming image.png. You can take a look at one of many layouts I created with MIDI DESIGNER.
So, based on what you mentioned, behavior is very normal (PC acting on PERFORMANCE list) in KEMPER environment, hence making sure to enable/disable relevant picker depending in which mode user is operating. I’ll add comment on my layout to warn other users about actual behavior.
For users like me who do not user physical MIDI controller anymore, do you think it would be possible to, eventually, add NRPN or SYSEX MIDI message allowing user to trigger switching from PERFORMANCE to BROWSE (and vice versa) via MIDI instead of having to manipulate physical buttons?
Not an emergency.
Have a great day.
