waldorf encoders
not so good from factory
capacitor fix
I thought the encoders on this little gem had gone bad. Jumpy, erratic performance and impossible to get smooth sweeps. I bought it used, but I got the impression that the previous owner hadn't used it much. So what gives? A little research revealed that this is actually a common issue from the factory--the software that reads the encoders doesn't do a great job of separating control data from noise (my understanding of this is pretty weak, but the way to modify the board to fix it is reasonably well documented.) Ta-da! Less than a dollar's worth of capacitors and a little solder and this thing works like a charm.
