Well then, I may have just what you are looking for!
It is a blast to play with, and from what I can tell based on videos, it sounds a lot like a true analog Benjolin.
It is meticulously patched based on the After Later Audio manual for the Eurorack module, combined with Rob Hordijk’s original Benjolin specification. I also add a few enhancements - mostly an expanded patch bay. But at its core it is a self contained experimental sound machine in a virtual box. Just hook up one of the filter outputs in the upper right patch bay section to an Audio module and start having fun twisting knobs in the upper left UI section. Or use two different filter outputs for some stereo action - I like to use band pass and low pass. Then do some self patching in the patch bay and see where it takes you. There is a universe of possibilities.
I have a newer version to post with a much improved UI using the Mind Meld Patch Master, but I am waiting for the immanent release of my Venom plugin - I use its window comparator to add a new feature - expanded patch bay with CV control of resonance, but the max resonance always remains clamped just below self oscillation, as is the intent of Rob Hordijk’s original design.
