I had the same problem. It turned out to be the potentiometer of the pitch control itself. It may not be for you, but when mine was changed the problem went away.

Hope this helps?

hi.

i'm doing  a lot of recording with #1300 and it started to give me problems. the motor is speeding up, slowing down, stopping and sometimes lurching fast and slow. i have one of Marcus' sms4 boards in it. when i touch the motor control cable connected to the board it seems to make the above mentioned problems go from one to another. maybe it's a short on the cable or the connector. any thoughts and or solutions from any of you owners out there? 

the wires are yellow/white/green/red/ and a double gray, in that order.

i'd really appreciate any help you folks can offer.

thanks,
