Hi,

I try to map an external midi controller with rotary encoders to microtonic AU/VST3. That doesnt seem to work. Microtonic knobs jump between min and max values but nothing in between. Seems logical since encoders (depending on the manufacturer standard) normally send 0 or 127 to increment or decrement.

In this case:
B0 00 7F
B0 00 01

I´ve got no problems mapping actual pots or encoders in absolute mode where continuous values 0-127 are sent.

Is microtonic capable of understanding +/- increments via Midi-CC?

Thank you

There is - to my knowledge - no such thing as MIDI messages for increasing/decreasing CC-values. In order to increment/decrement a CC-value using a rotary encoder, the controller needs to receive the current CC-value.
And it depends on the setup of your DAW if and which knobs of any VST is sent out to a controller.
Hope this helps a bit.
