Emax

IC35 is labeled TMS4256-15NL
it should be something like a ram chip.
i wonder if it is responsible for the stucked notes problem which is the 
most annoying one.
 i don't really care for missing notes, i will have a go at the filter 
calibration procedure to see if i can find which is the missing voice. 
then  maybe swapping a couple ssm filters and vcs from a dead siel 
expander will do the work.
I don't know anything electronics, sorry if i'm talking nonsense:)

thanks,
davide
