I can send midi to cubase successfully to automate quickcontrols. But how do you send midi from cubase back to the controller so automated sliders and knobs can be put in the correct position?
yes, just make sure you have configured
- the midi out port
- the transmit flag
Set, what @Nico5 suggested in the Studio Setup > Track/VST Quick Controls.
Be aware, some encoders expect other MIDI CC on the input side (comparison to the MIDI CC they send out) to light up the LED ring around the encoder. If this is the case, you have to modify the out data in a 3rd party software.
