I have bought a nice new Komplete Kontrol S88 MK2 controller, but have some issues with using an expression pedal with it. Connecting and setting up the pedals is done, though as many learned, not very intuitive.
The regular pedals (sustain and a 2nd switch through a Y splitter) are working like the should. Only my expression pedal is showing strange unstable readings. What I see is that the readings jump up and down: eg if the pedal is half open it jumps between 50 and 80.
I tested this with 3 pedals: Dunlop DVP3, Roland EV-5 and Boss FV-500H.
When testing on my Kurzweil, they all work and are very stable.
Is this something known? I could not find any other related topic in this forums, if there is feel free to share.
