Well don't I feel silly...

thanks jay :)

i must say, both versions of the synth are really phenomenal, it's just an
incredible combination of patching and basic tone-shaping that remains
stunning even compared to everything you can do with max/sc/whatever

the original filter has a jaw-drop capability that has caused it to go
beyond just being an excellent design, and really this comes to the fore
outside of simple tone shaping of pitched oscillators - some strange
patches on the MS20 may venture into this domain

but really, you have to feed it with a more complex signal than oscillators
- i'm talking an entire mix, or a very complex texture, or natural 
recordings,
or drums, and here, the stuff you can do with it is breathtaking, and this
is how it became a legend amongst dance remixers: It has something that
the moog certainly has nothing of, and it's totally strange

one time i was mixing a track, and it was, just a little too clean, and i
had the MS10, so i put the vocals half through the filter, with the cutoff
on max (way above anything audible) and the resonance somewhere higher
than oscillation, but, at that frequency, it probably wouldn't oscillate

the mix just burned, beautifully

from that day on, i wondered about that thing

MS-20 units fitted with LM13600 filters have a small daughter board; the front panel on such units often has a tell-tale mounting screw whose head is visible in the vicinity of the VCA block diagram. However, a report to the Analogue Heaven email list in January 2010 identified an MS-20 with the front panel screw but containing the Korg 35 filter thick film circuit rather than the expected LM13600 circuit."
