Just talking off the Korg 35 IC ,some people claim and complain
about the higher noise level from that filter in the OLD MS20
i just had look into the Korg PS3100 shemo, this fellow has 
one Korg 35 filter per each key??

That would asume that it would add up more noise as one plays more
notes,
imagine a two hand accord of 8 notes, that would be like 8 old MS20's!!

The PS3100 has the same out VCA as the Old MS20!
