If the LCD is randomly jumping to certain pages with the addition of parameter values changing on their own, please try the following steps to resolve this:
- Locate the panel knobs for the parameters that are affected
- Rotate the knobs clockwise a full three times
If the above doesn't solve the problem, check if there are any external MIDI devices sending MIDI messages to the synth that could cause parameter value changes. To determine this, try disconnecting all MIDI cables from the synth - if the behaviour has now stopped the cause would have been a MIDI device.
