The early ones (Korg 35) are remarkable for their unique filter design
- remarkable from an engineer's point of view - but the later ones
(LM13600 based) just sound better (IMO). 
They have practically the same character - the unique MS-20 resonance
behaviour and all - but the 13600 versions are less noisy and have
less CV feedthru in the filter.
