Came across this just now, was mapping out all CC positions of a modwheel (for sampling purposes) CC1-CC127
It appears I hit some kind of limit whereby naming the custom ‘Art.’ Articulations was not properly reflected/messed up something in the Sound Slots ‘Art. 1’ name column
edit
I think I fixed it, I think the issue was caused by ‘Adding Custom Articulation’ which defaults to a Symbol, and somehow, in this process, Slots ended up sharing the same articulation in stead of creating a new/their own.
