Continuum has it’s roots in my previous guitar effects pedal designs. First there was Causality 4, then Causality 6, then Gemini Dual Core.
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.
Wanna hear it? First, let’s phase some pink noise:
So now, with a couple of VCOs as audio, let’s send S/H into one CV input then an ADSR into the other, while slowly turning up the resonance:
Now, a single VCO as audio, with ADSR to one CV input of Continuum, and slowly introducing a -1oct sub osc to the other CV input:
Finally, here’s how it sounds phasing my Roland RS-09:
Continuum is 10HP and 60mm deep. Price is £160 GBP
