I have bought a second hand Moog Voyager (Aniversary edition) in quite good condition, however, I am suffering from a malfunction, which is that after a normal operation for about 15 minutes, the synthesizer stops producing sounds. Any sound. Although the Voyager does normally send MIDI messages to a slave synthesizer, so I rule out a problem with the keyboard.
The failure usually coincides with a quick parameter change, but sometimes only with a quick interpretation, but not always. It gives the impression that some kind of overflow has occurred.
It is easily corrected by switching the unit off and on again.
Has anyone experienced this type of malfunction?
