Win10, Studio One 6 Pro, X-Touch MINI ...
I think I have routing correct as the initial learning works fine.  I go thru the process and save the preset.  I verify by changing, then reloading the preset.  All is good.
When I come back to the preset a few days later, the previously learned MIDI assignments are gone like they never happened.  Again, the routing appears to be correct because everything readily learns again.
Anybody else?
