I've been experiencing problems on my Kurzweil Forte with the pitch wheel randomly changing pitches just sitting idle (I can see it on the display) or while I play. This is very irritating and has messed up more sessions that I care to count. Some midi tracks in a session have also been affected.

Can someone please provide a step-by-step fix to disable the pitch wheel so I can get some session work done? I was reading online that you can go into the Control setup area and set #126 to not go past 0 either way, but I don't even know how to get into that to fix it. Also, if I need a pitch wheel assembly replacement, please also advise how I can order one of those. Who sells those? I need a quick fix in the meantime.

Additionally, do you know where I can find the serial number to my Kurzweil Forte? I was trying to avoid turning it upside down to find it in case I need to reach out to Kurzweil directly! Thanks for any help you can provide.
