I looked at the data sheet. It would require a daughtercard approach to
use the filter as the chips are not pin compatible. Other features (it is
similar to a CEM3372) would be turned off, too. Although, it has a final
VCA on it that has got to have better (less) CV feedthrough specs than the
Korg 1-Transistor Wonder. It could probably be used to replace the
SSM2044 and the VCA for each voice. It just needs a small PC board.
Regarding MS-20 filters, both the "Korg-35" (transistor SIP) and the
LM13600 (OTA) circuits are 2nd-order Sallen & Key models.
