Metasonix RK5 Dual Low Pass Gate

Published on Dec 30, 2019 CatSynth TV

"We explore the Metasonix RK5 Dual Low Pass Gate. A lowpass gate is essentially a low pass VCF configured to behave like a VCA. The RK5 is a unique take on the LPG with two independent channels that have their own sonic characteristics. It is extremely simple, with just input, output and a single CV per channel. We demonstrate it with envelopes as CV and a variety of input spirses.

'Since part of our remit is to explore an electronic-music history that didn’t actually happen, one inevitable product would have been a lowpass gate. Our version is a dual unit, dead simple Sallen-Key filter with just input, output and CV input for each channel. The tube used is a “high-perveance” dissimilar dual triode, the 17JK8. It was apparently intended for use as a “cascode” RF front-end amplifier in cheap consumer FM radios.'"
