Reply to VCI-100 SE Jog Wheel MIDI Issue

Hi,

My VCI-100 (Firmware 1.3, arcade mod and overlay) right jog wheel is giving me problems.

When spinning it round, it keeps sending stop and start messages during the rotation. This has the effect of spin, then stop, spin then stop when attempting to cue in Traktor.

I have taken the unit apart and examined the jog wheel mechanism (The flat silver disc with micro perforations on the outer rim) and noticed that it's not flat. So when looking at it from the side when spinning, it looks like a warped record.

The small reader on the side of the disc looks like an optical device which reads the speed and direction of the disc when spinning. My guess is the bends in the disc are causing the reader to misinterpret the data as starting and stopping.

I have used contact cleaning fluid to clean the disc in the past and it's fixed things for a short while, but it always seems to screw up again after a while.

Any suggestions?
