Wonder if anyone can help. The mod wheel modulation bus (and possibly the pedal one!) seem to have broken.
A lot of patches have extreme LFO modulation, and I can't get expected results when programming.
The simple vibrato walkthrough on page 32 of the manual does has no effect, and the pitch continues to modulate widely regardless of amount or modulation wheel position. No expression pedal plugged in, and pedal/on bus amount is 0.
The moog has never been gigged, had no knocks, has had light use, and is now i think 5 days out of 1st year of ownership. I think that means the warranty is done.

If anyone can think of anything dumb i've done, or that I should try before getting the machine serviced, please please let me know

Many thanks.
Phil
