Discussion about the Korg PolySix synthesizer

Hey gents,

I am about 3 months in with my new PolySix and super excited to be owning one. I am by no means of engineer so I was hoping I could turn to the experts here for some help.

My problem is that I am not getting any modulation in the MG section with the switch on the VCO. The VCA and VCF MG work just fine. I am also not experiencing any changes when using the pitch wheel, or changing the master tuning knob position.

I feel maybe i must of touched one of the VR's during tuning that has disabled these because I vaguely remember it working when I first received my Polysix. 

Any help would be much appreciated, I miss my vibrato!
