Harmonic VCO

VCO

Unique VCO. It uses FM to produce different waveform from a sine wave core

It is a true sine wave core.

Gradually morph from sine to Even Harmonic (saw) and or Odd Harmonic (pulse – PWM also possible)

CV control of both morph parameters.

Stable sine core VCO, less harmonic distortion and good tracking.

Inspired by Rob Hordijk’s „HarmOsc“.

A good source to start to understand this unique oscillator see Hordijk’s tutorial videos ot „vimeo“.
