Moog Rogue Auto Trigger problem

Hey guys, I was wondering if anyone could offer any help/insight in aiding me with the repair of my Moog Rogue. The issue with the synth is that When the Auto Trigger when turned on note that is triggered slowly raise in pitch, I immediately thought it seems like a problem that would be caused by a failing/leaky cap and after searching around online it seems like it’s most like a leaking sample and hold circuit (please correct me if I’m wrong), now I’m not too familiar with synth circuits yet so I was wondering if anyone would be able to help me narrow down my search for the faulty part.
