Optotronics Delayed Twin Oscillator Standalone Desktop Stereo Delay VCO and VCA

The Optotronics Delayed Twin Oscillator is a continuation of the M*therfucker effect pedal, except it is stereo and contains more elements.

Features:

• Two Voltage controlled oscillators (square waves)
• Toggle switch for high range (VCO mode) and low range (LFO mode)
• Modulation switch:
• left position: osc does frequency modulation of opposite oscillator

• right position: osc does amplitude modulation of opposite oscillator; 1c. FM CV input

• Sliders:

• Glide/portamento – switches between ‘staccato’ and ‘legato’ mode
• FM – sets the amount of Frequency Modulation

• Freq – set the pitch

• Two Voltage controlled amplifiers: 2a. VCA Control Voltage input

• Volume knob (act as attenuator on incoming CV)

• Dual Delay Effect

• Input
• Output
• Delay Length
• Feedback Delay
• Delay Control Voltage (vactrol)

There are plenty of ways to play around with the DTO and you don’t need to know much about eurorack, or control voltage, but if you want to you can easily implement external voltage control. You can also play around with the oscillators while having the inputs engaged.
