Moog Source

Post by ursula peruke » Thu Jul 21, 2016 10:33 am

I 'm having real problems with my Moog Source. The optical imput knob will not go backwards (decrease) values. We tried new sensors but nothing seems to work. This is a vital piece too as it changes all parameters and storage. ANyone knows a work around or suggestions for a fix? thanks,

Hello and welcome.

The encoder working in only one direction is an indication that one of the logic gates might be malfunctioning in the encoder part of the circuit.

I also heard that the distance between the two optocouplers that read the direction of the optical wheel makes a difference. Good luck.

I just saw this today but yesterday posted my repair of a Source Incremental Controller http://forum.moogmusic.com/viewtopic.php?f=1&t=26034. I had to make three modifications to use different sensors. The standard LED current is way too high, the pinout was different, and I had to adjust the phase delay between the two outputs. Details are on my Moog Source page at http://modularsynthesis.com/moog/source/source.htm. Good luck.
