Thanks for your continued help.
To clarify: I previously used the 3 button switch for the tuner. It now is all mapped solely for the looper.
Switching to next higher preset is now all done with the midi switch, and it was only with one preset, so I thought it was determined by the preset rather than a global function.
For example: going from 12->13 = 13. and going from 13->14 = 14. But: 14->15 = tuner active (15 is then active when turning off tuner). Going from 15->16 = 16, 16->17 = 17, etc.
