Archive of the former Yahoo!Groups mailing list: Discussion about the Korg PolySix synthesizer

the last time i cleaned my key contacts i used alchohol and a q-tip,
but the results didnt last and were inconsistant. Some notes
were 'sluggish',almost had a delay, others had to be hit multiple
timrs...... So I recently cleaned them again, this time using LIGHTER
FLUID (ronsonal) and a q-tip. I was very careful not to get the fluid
on the laquer of the pc-board, Interestingly, i got a black residue
from many of the round magnets on the q-tip,(but not all) . i NEVER
got any signs of residue using alchohol. Now the keys work great, all
instant contacts, no sluggish response. Perhaps this stronger solvent
is more effective? seems that way to me.
