Lot of filter expansion for mutable instruments, somenone here try to build a module eurorack arround SM4 or other filter kit?
The Shruthi filters are designed for +/- 5V supplies, 0.46875V/Oct, and their board size doesn’t fit in a rack.
There are already excellent Polivoks, MS20, or multimode/SVF filters.
Want something 4PM-ish? Ripples.
SMR4? Well I might work on that at some point.
