Fender Cyber foot controller, 2001
 

14 switch and 2 pedal, midi output guitar pedal.
One pedal not working - hope its not the pic chip.
At the moment exploring the horrendous squeel from the pedals.
Seems that for neutral hold, ie stays where the foot angle was last , relies
on a steel sleeve inside then the moving and mount-steel plates, either
side, and a through-bolt with nylock nut supplying enough pressure to make
resistance to movement, as axle. But it is steel plate turning against steel
plate on either side of the pivot - urgh !
How to deal with the squeel, oil would loose the neutral or dead action ?

As an aside
Anyone know of a simple circuit for exercising/testing midi, both in and
out, without tying up a scope or a pc, ie just to check that there is a
functional change in the signal.

looks as though the problem is in the unseen amp, foot controller sends out
midi signal on all functions

Fault on the "continuous" controller probably a case of RTFM
From a Fender Cyber amp manual
If "The unit is not responding to any MIDI continuous controller messages
from external devices...
Make sure the continuous controller numbers matches the value in the UTILITY
menu or is one of the predefined numbers listed in the appendices."
