Hi!
The glide doesn´t work very well on my Minimoog model D. Turning it up to just over 3, and everything is fine. If I turn it further up, the Minimoog doesn´t respond to key pitch, and it makes a very slow glide. Is there a trim pot I can use to solve this problem?
A bad FET would likely cause key CV problems regardless of the glide switch or amount setting. Besides. a novice stands a fair chance of replacing a non polarized 1 mf cap without error - an FET replacement opens the door to a list of errors. Sure - I’m making an assumption here, but asking if there is a trim pot to fix this problem indicates an entry level awareness at best. He probably needs more assistance than we can give him on this forum if there is a bad FET.
Here is a test you should try Patrick: Forget the glide for the moment and turn the switch off. Flip the decay switch on the left hand controller panel to put the ADS circuits into release mode. Turn the decay controls fully clockwise. Play a high note on the keyboard and monitor the pitch drift (with your finger removed from keying the note). A leaky C6 will cause that note to drift noticeably flat. When the key CV sample and hold circuit is working properly, C6 will hold the CV long enough for the note to completely decay on pitch. Note, however, that this circuit becomes an issue when operating the model D as a module. That key CV needs to be disconnected from the VCO summing nodes when using external CV control as this voltage bleeds off of C6. In a matter of some minutes, it will go significantly flat even when working properly.
