Hi,
it's probably similar to the Memorymoog, which has an additional CEM3340
as an LFO.

The JP8 has additional filter chips for static high pass filtering. On
the front panel it's shown to be in the normal signal flow, but actually
those HPFs are located at the end, common to all voices, but separate
for both split/layer parts. So, IIRC there are 10 VCF chips in total
(haven't verified this right now).
