I'd love to see inside these too, the MiniKorg has one of my favourite
filters.
Are they just small circuits potted in some compound ?
If so, maybe there is a solvent that will remove the potting and reveal the
circuitry.

Is there any similarity between the Keio filter modules and the Korg 35 ?
They couldn't be the same circuit with a different name ?
