Yeah, the Morgasmatron at the very least is definitely one I'd like to own at some point.
As I often seem to do, I went on Reverb the other day with the complete intention of getting a sequencer and a VCF, and ended up buying up something completely different. I somehow came away with a Xaoc Kamieniec Phase Rotator, Nonlinearcircuits Multi-Band Distortion, and Instruo Lubadh, none of which I'd remotely intended to buy.
While not exactly a filter, I'm hoping the Phase Rotator scratches a similar kind of itch for the time being, it seemed really interesting to me, price wasn't bad, they're hard to find right now, and I like the couple little Xaoc utility modules I have pretty well. The Multi-Band Distortion I just jumped on bc it seemed a good price, I don't see them often, and I love anything that allows me some control over EQ -- if it's distortion oriented, all the better. And the Lubadh, I have no idea really ... seemed a good price for one considering it was being sold with the expander, I've wanted one since I first started modular, and I'd just watched a demo of one that got me all juiced up.
As a kind of tangential question to this thread, I wonder what people consider their favorite "budget" VCFs to be, VCFs for under $200 that hit above their pricepoint in your opinion.
