Hi,
I have a Prophet 08 converted to PE.
After changing it over everything was working just fine for a certain time.
I didn't touch the synthesizer for several months and now I discovered that one of the potentiometers does not work as it should. At first, it jumped from 1 to 127 without intermediate values. After calibration, it reaches only the value of 20 jumping to 127 at the end of the scale.
I tried air duster, was changing PotMode settings - all without much effect.
In addition the value of the parameter starts to "tremble" closer to the end of the scale.
I've searched this forum for a similar issue, but didn't find an example describing exactly my case.
Do I need to replace the potentiometer somehow or is it possible to repair it?
