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.
  • 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.

This module is built using high quality electronic components, Switchcraft jacks, NKK switches, Cosmo knobs (the same used in the Moog Modulars) , black anodized aluminium front panel ( like the original Moog Modulars )….
