hi! I owned second hand DOEPFER POCKET DIAL for some time and two right knobs make a lot of value skipping 
turning right I get values like +4 -3 +1 -2 +2 +1 -5 -2 +2… is there any way to “clean” the encoders or what? does it help do remove detents? how to do this? thanks for reply
…no reply from them >:(
can anybody help?
That´s typical for Doepfer. You won´t find anyone here who likes them to much (I do think so). They more or less are selling stuff for a to high price and 90% of it can *easily* be done DIY (especially the modular synthesizer stuff).
The support @ Doepfer is known to be a shame. They normally *will* answer you, but that can take a few days up to weeks. If it´s some urgent stuff, I would call there. You can also look for forums on Doepfer stuff.
There is a forum link on the Doepfer homepage:
http://server3.ezboard.com/bdoepfermusicelektronic (and there the Pocket Contolers even have its own section)
Try it over there or build the better MidiBox.

… why don’t replace them, if they’re ALPS?
