The MS-20 is a strange compromise. The signal path is fixed,
supposedly to save on sockets. At the same time, EG1 has two
outputs (normal and reversed). Which is just as well because
none of the modulation pots are bipolar.

PWM ? Sync ? Audio-rate modulation of cutoff frequency ? Forget
it.

The modulation is limited too. There are six modulation pots for
the VCOs and VCFs but only four possible sources because they
skimped on sockets. And you can't modulate either VCO
independently.

That said, the original (Korg-35) version sounds wonderful. IMO,
doing a modernised, 1 V/oct version of the electronics of the
MS-20 is worth it... if you replace the front panel by one with
twice as many sockets.
