FM (algo) VCO

Modules VCO

Here’s an alternate FM VCO based on my modifications to the Library VCO but with some UI changes and the addition, inspired by RYK’s ALGO oscillator, of a multiplication knob for the root pitch, all with the idea to making it a more suitable building block for an FM playground.

Here’s video of the VCO in combination with my Hordijk 24dB Filter.
The bandpass and highpass signals are coming from the Hordijk Sync Oscillator, and the lowpass is from FM VCO – I’m simply doodling around with multiples of the root frequency. The Triple LFO is modulating the filter cutoff and resonance, and there’s a healthy dose of LexPlate reverb to help it all sing.
