HI-Fusion VCF is a redesign of a classic high pass OTA VCF with corrections and addons.
It's working very well on v/oct and with FM modulation on FREQ cv input.
It's one of the best VCFs based on LM13700 chips, sounding like the classic SH and System filter.
(It contains 4x2n5457 FET transistors available easy on ebay)

More information will be available soon.

We uploaded the schematic and BOM, but we are still working on the manual.

We used two oscillators slightly detuned as the sound source.

Output with switch in 4Pole position.
