MOTM

I just got my Kenton Pro-2000 and am finally getting to hear my MOTM set-up. My 800 (I only have one right now; the second one should arrive 
this week) is not functioning as I expected it to. The Decay and Sustain are working oddly. I double checked the wiring and layout and I think I 
got it right, but I'm not confident I have the Kenton set right. Could someone tell me what the proper settings are?  I'm particularly confused 
about the gate voltage setting. It talks about the gate being +/- 5v, but also talks about +15v. 

Thanx,
Mr. Nezumi
