NoisyFruitsLab DCO - Dual Wavetable Oscillator for Eurorack Synthesizer

video upload by NoisyFruitsLab



"DCO stands for 'Detox Controlled Oscillator' and is a dual wavetable sound source for creating big things on a small footprint

Designed for stereo or duophonic fun as giant wavetable for each oscillator, containing 30 waveforms for each.

With an own output for each oscillator and an accurate frequency range from 0.01Hz to around 10KHz it´s an excellent audio source, LFO and reference as well.

CV control for each wavetable (-5V – +5V)
Shared 1V / octave input, covering 10 octaves (-5V – +5V), FM friendly

Bipolar LEDs as negative and positive indicators.

Frequency and wavetable control for each oscillator with smooth endless rotary encoders including buttons.

Covering fine or stepped frequency adjustments for detuning, harmonizing and chordifying.

Blend smoothly through a giant wavetable with 30 different waveforms for each oscillator with the encoders or over CV.

Switch between sync modes, so oscillator 2 get´s independant cv control over waveblending and frequency, or choose the “no CV” mode for highly accurate reference frequencies.

User friendly 11-point calibration mode.

Update friendly and designed as partially open source project and development platform."
