Yamaha Motif XF8 Faders Increases Itself On The Screen

Hello buddies,

A Yamaha motif xf8bwas brought to me to troubleshoot for repairs.

I noticed during performance the fader 2, Fader 4, Fader 7 increases itself on the screen without manual adjustment.

Please what could be the problem? Is it the voice volume faders or the panel board is having problem.

Please i look forward to your earliest reply on this.

two things:

  1. What FW version is it running?
  2. Have you tried Factory Reset (take setup copy first) ?

I haven’t check buy would do.

But could this issue be software problem or hardware??
