Verbos Electronics Harmonic Oscillator

The module's left side is known from classic VCOs as it contains coarse and fine frequency controls, a linear FM input with attenuator, an exponential CV FM input with polarizer and an 1V/octave input. Also there are outputs available for triangle, square and sawtooth. So far so good but there's a fourth output, carrying the harmonics' mix from the right side of the module:
This part generates eight sine waves corresonding to the fundamental tone and seven overtones. Each harmonic's level can be controlled with a fader and a CV at the input underneath. The harmonics are available at individual outputs on top as well which can be pretty interesting in combination with a stere mixer with panorama functions.

Very interesting are the parameters in the black block as they provide manually and voltage controlled for unique treatment of the frequency spectrum, independent of the faders' settings:
- Harmonic Scan does scan through the frequency spectrum, with center and width determining the center frequency and width of the "bell"
- Spectral Tilt either emphasizes the low or high harmonics.
