Verbos Harmonic Oscillator Module

For the first time in Eurorack, this oscillator module provides outputs for the first 8 harmonics as sine waves. Also included are triangle, saw, square waves. A voltage controlled mixer with various methods of address allows the user to scan, tilt and mix the harmonics from both panel and external voltage control.

It is built on a discrete, all analog triangle core with an old school discrete transistor exponential converter. It has inputs for linear and exponential FM, the exponential with a reversing attenuator. Of course there's a 1 volt/octave trimmed CV input as well.

The Oscillator Core
The oscillator is set to range from 3 Hz to 20 kHz from the panel “Frequency” control. It has dedicated outputs for triangle, square and saw waves. The “f.m. input” goes through an attenuator on the way
to linear modulation of the frequency. The “c.v. input” goes through a reversing attenuator on it’s way to exponential modulation of pitch. A calibrated volt/octave input is also provided..

The Harmonic Mixer
The section at the right side provides outputs for the first 8 harmonics. Each harmonic has a slider and c.v. input for control of it’s level in the master output, indicated by an arrow from the mixer.
The “width” and “center” controls allow the harmonics to be swept across like a bandpass filter. Reversing attenuators are available on both inputs.

The “tilt” control as turned up will favor the higher harmonics and reduce the lower harmonics. Turning the control down will favor the low harmonics and reduce the higher ones. With this control centered, it has no effect on the harmonic mix.

LEDs indicate the state of each channel in the voltage controlled mixer section.
