I have the midi controller arturia minilab which has relative (endless) encoders. They work fine in their own software, meaning no jumps in values.
In Cubase the “knobs” on the screen always jump to the last value of the knobs on the controller, rather than increasing or decreasing. I have tried all kinds of flags in the remote controller setup in cubase, but to no avail. It always jumps which makes the whole thing rather pointless.
Minilab has its own midi setup software but this can’t be run at the same time as cubase, and in any case seem to have no effect on cubase at all.
