Phase Synchronized Dual Oscillator With Audio Rate Modulator

Phase Synchronized Dual Oscillator
Freak is a dual oscillator for Eurorack modular synthesizers. The two digital oscillators can be phase synchronised with each other and have dedicated audio outputs. This makes it easy to process them separately while resulting in sharp and well defined bass and lead sounds. The integrated audio rate modulator creates complex and interesting timbres in an instant.

Effortless Yet Powerful
Modern music production techniques often rely on layering instruments to build the final bass and lead sounds. Drifting phases between layers make the sound less defined and less sharp. If sharpness and definition is the goal, the challenge usually is keeping the sound layers phase synchronized. This can be cumbersome even on modular systems while modulating two oscillators in audio rates. Keeping the layers in sync could become impossible if different synthesis methods are used for each layer. Freak has been designed to address this issue.

Freak contains two oscillators. Oscillator 1 consists of 8 different waveforms and has a dedicated audio rate modulator. Oscillator 2 consists of 8 more complex sound generation algorithms. Both oscillators can be phase synchronized when needed.

Both oscillators have their own dedicated audio outputs. Mix Out provides an easy way to crossfade between the two oscillators.

Several different synthesis methods are used to create a wide palette of layered sounds: virtual analog, frequency modulation, phase modulation and phase distortion. The UI has been designed to make sound design workflow quick, easy and intuitive.

Main Features

Two digital oscillators + one audio rate modulator
Oscillator 1:
8 waveforms
Each waveform has a synthesis method specific control parameter which can be modulated with the audio rate modulator.
Wave 1 = PWM
Wave 2-6 = Phase Modulation
Wave 7-8 = Timbre
Syncable to the audio rate modulator
CV input for controlling tune
Dedicated audio output
Audio rate modulator:
8 waveforms
Modulates Oscillator 1 with 4 possible modulation modes
Frequency modulation at octave 0
Frequency modulation at octave 1
Control parameter modulation at octave 0

CV input for controlling modulation amount
Oscillator 2:
8 waveforms with two controllable parameters each:
Pulse = PWM / Phase Modulation
Double Saw = Saw mix amount / Phase Modulation
Multisaw = Number of saw waveforms / Wave spread
Gnarl = FM Timbre 1 / FM Timbre 2
Whoosh = FM Timbre 1 / FM Timbre 2
Blip = Phase Distortion / FM Timbre
