All I can say is that with detented encoders it’s pretty hard to accidentally change values while using the button. Don’t know about undetented ones though.
I’d not considered that is what it means.. I was thinking in terms of ‘pan’ style pots where there is a single detent in the centre.
… this is not possible with a regular encoder.
The 4 STUDER OnAir3000 CentralScreen rotaries (3rd touchscreen on the right of the desk picture) have a magnetic clutch/break, which makes the non detend encoder feel like a pot. - Left/Right stop and center detend.
