Vintage Synth Repair

It sounds like a contact problem for the low C key - The control voltage
does not work but there is a trigger so the previous note will be
retriggered when you press the lo C.

 

I don't have the schematics so I don't know if it uses a dual contact
keyboard or another arrangement (e.g HF signal on the keyboard bus). I
suggest that you dismantle the keyboard from the synth and check/clean the
contacts.

the problem im having is ....

when i turn the unit on..and play the lower "c" it plays 
fine ....UNTIL i play another note ....then it no longer plays a "c" 
it plays what ever note was last played... for instance...if i press 
high "a" then low "c" i hear the high "a" agin (instead of the low 
c)....it does this no matter WHAT key i play....low "c" will always 
repeat whatever note was played before it.

any suggestions on how to fix this????
