Hi!
Is there some update on this issue? I still have the problem (with the cutoff knob being the worst and the others except the last 2 on the right working bad but in a usefull way) and the firmware is up to date now on february 2020. I had also the resonance knob working very bad a month ago, but after a couple of days it returned to the standard working (not perfect but usefull). The counterclock rotation didn't produce any change in the software parameter, except going from 100% to 0% in a moment.
I opened a support ticked when I bought the keylab an year ago and the responce was
"As an information, the encoders on the keylab essential being not high end encoders as on other range of products which would be more expensive, some inconsistencies can be observed on slow rotations.
In this case, if you imperatively need extremely accurate encoders at very slow rotations i cannot guarantee you that there will be a definitive solution for these issues even if we'll make sure to see if a potential firmware version could help solve these in next updates.
Indeed, if you're facing such inconsistencies on normal or faster rotations there's perhaps something abnormal and if you can eventually provide us a small video this would certainly help us confirm this."
but i saw the problem was well known from they so I didn't procude any video.
hope there will be a solution!
sorry, just saw in midi control center that a firmware update was ready to be installed. it solved all! great work. next time, maybe tell us about the update
