Update – I’ve made a couple of corrections – see below —
I’ve worked on this for days and it’s done. I added a PatchMaster UI for it so other people could program it. Like the CS80, it can’t directly save patches, but you can save your patches as new VCV files.
I think all the settings are dialed in, but if you run into something, report issues your issues and I’ll fix it.

Modifications to original posted version:
So, here are the corrections I made – I increased the range on the mapping of the LFO accelleration to give wider accelleration. I’ve also turned down the slew limiter from 1.5 to 1 second for the speed the aftertouch LFO accelleration kicks in. Third, the Portomento wasn’t fully turning off, so I adjusted the range to 100 to 0 on the VCF that controls the portamento.

Thank you for putting this patch together, days of testing must have gone into this!
A magnificent rendition of a mysterious beast of a synth!
Much appreciated.
Wonderful!
Thanks – I did make a few last minute changes and two of them bit me. The Portamento wasn’t fully turning off, so I fixed the range mapping of the portamento amount to open the filter fully when turned off. And I realized there needed to be more range to the LFO speed increase on aftertouch, so I increased the max level and turned the slew limiter attack down.
Lana, there is a thread on VCV Rack community with some great comments and possible alterations with different modules. See what you can glean from the fine forum users. The latest ones are about this patch.

Hope these help.
