Frequency Central - Continuum Phaser II [eurorack]
Allpass VCF for Eurorack
Continuum looks and acts rather like a VCF, in fact that’s exactly what a phaser is, an all-pass VCF. There’s far more to phasers than just sweeps up and down from an LFO, so Continuum has two CV inputs, so you can use a variety of CV sources simultaneously.
The topology of Continuum is 4 swept OTA all-pass filter stages with a fixed all-pass filter stage either side of the swept core. There’s a switch to select regen over odd or even stages. Most phasers stick to odd stages, but there are undiscovered sonic possibilities using even stages of regen.
