If this has the usual two-buss keyboard (with two contacts for each 
key:  one for the note, and one to trigger),  then it's likely that the 
note contact for middle c is not making contact (broken or bent) -- this 
would result in the effect you describe, since most of those older synths 
have a "note memory" that retains the last control voltage until a new one 
is played.

rogue key doubling

2004-12-10 by Mubo

Hi there!

was wondering if anyone has experienced this....

whatever the last note is that i played gets repeated when i press my 
middle c key ....

i dont hear the middle c note... i hear the previous played note!

same octave..everything...

if i play a high a note...then press middle c ... i hear the high a 
again..

ok...now that i have overly explained it  ...ANYONE GOT ANY ANSWERS ?

thanks for the help!!!!!

FIXED!
 thanks so much for an informative bit of info and trouble shooting...
the 2 bus information gave me exactly what i needed to know what to 
look for...

turns out there was some black stuff on the contact that i didnt 
notice before... i trimmed the contact and resoldered a piece of 
copper...and BOOM.... WORKS LIKE A CHARM!

2 years of posting on different groups and i get no worthy help until 
NOW... thanks again !!!!!!!!!!!!!!!!!!!!!!!!!
