Future Sound Systems OSC1 Cyclical Engine

The OSC1 from Future Sound Systems is a 14HP voltage-controlled analogue oscillator with a few features unexpected of a basic oscillator, with particular focus on covering all bases of signal modulation. Once triangle, sinusoidal and pulse waveforms are derived from its sawtooth core, each waveform is passed through a VCA. The outputs from these VCAs are then summed at the Mix output, which can be switched between 2- and 4-quadrant-multiplication modes. These two QM modes allow for a plethora of amplitude modulation effects to be achieved. Level controls for each waveform dictate both static level, but also depth of modulation through careful design of the control summation. Each individual waveform output is taken pre-VCA for maximum patching flexibility.

Shape modulation of the triangular, sinusoidal and pulse waveforms is also available. Both the triangular and sinusoidal waveshapes can be skewed forward or backward into ramp-like shapes, whi
