C104 Odyssey of Sound VCO

The C104 Odyssey of Sound VCO is a voltage controlled oscillator based in the discrete core of the ARP VCOs ( 2600, Odyssey… ).

The oscillator has four waveforms available simultaneously (sine, triangle, saw and square with variable pulse width). The square wave pulse width goes from 10% to 90% and can be over-modulated. This feature makes possible to created sounds that are not possible in other VCOs.

In addition to the VCO, the module includes a Ring Modulator (CMOS) and a Diode Soft Clipping circuit that can be voltage controlled. The RM and the DSC have independent outputs.

VCO

• Wide frequency range from 5Hz to 30KHz.
• Perfect tracking over at least 8 octaves.
• Coarse and fine frequency controls.
• +/- one octave switch.
• Temperature compensated.
• Four waveforms available simultaneously: Sine, Triangle, Saw, Square.
• Square wave pulse width 10%-90% allowing overmodulation.
• Hard sync input.
• Two 1V/Octv inputs.
• One exponential modulation input with level control.

Ring Modulator ( RM )

• CMOS based (like the original ARP Odyssey).
• Independent ouput.
• VCO Square wave is internally connected to the Ring Modulator.
  
  

Diode Soft Clipping ( DSC )

• Soft clipping level control.
• Soft clipping level can be voltage controlled.
• Independent output.
• Two waveforms available, ( triangle and saw ) selectable by switch.

All these features makes the C104 Odyssey of Sound VCO a versatile oscillator with a sonic range not available in other VCOs.
