Feague 1

Feague is a 4 pole VCF and quadrature oscillator. I use 2 in this vid, one as a VCF fed a steady signal from a VCO. The other is used as a QUO and gets modulated and sync'd by a LFO to get some burst action going on. The QUO output is controlling freq cutoff on the filter.
PCBs and panels are available for DIYers or you can buy it assembled if you prefer to just make music. nonlinearcircui...
btw - the circuits are exactly the same in both Feagues, QUO mode is obtained by cranking the Q pot up to 9-10. The panels are just different versions.
