OSC2 Recombination Engine

The OSC2 from Future Sound Systems is a triple voltage-controlled analogue oscillator Eurorack module with a focus on wave-splicing to produce new, harmonically-rich timbres. Each oscillator is built around a new-generation CEM 3340 VCO chip to ensure ultimate tracking and linearity across the frequency spectrum. The OSC2 employs its three VCOs in a master/positive slave/negative slave arrangement at its Glue section. Sinusoidal, triangle and ramp waveforms can be mixed at each slave (DNA) VCO through SSI2164-based VCA sections, which are switched between at the Glue section in accordance to the master (Scissor) VCO.

The VCOs of the OSC2 also allow for switchable linear or exponential FM and offer very wide frequency ranges between Coarse and Fine tune controls. Both DNA oscillators' VCA sections are accessible through the Mix Outputs, with the level controls operating in a similar fashion to those found on our OSC1 VCO module. At 12 o'clock, each waveform is modulated at full-scale by the applicable positive or negative state of the Scissor VCO's pulse wave. At 5 o'clock, each waveform flows through its VCA at full scale. Meanwhile, each waveform is available pre-VCA at the Raw Outputs.

As part of the Scissor section, three modulation busses can be switched on and off. PW Skew ties the pulsewidth modulation bus of the Scissor VCO to the frequency busses of the DNA VCOs. This means that, if the positive region of the Scissor VCO is elongated as the pulsewidth is increased, the frequency of the Positive DNA VCO is decreased, so that the positive portion of the Glue waveform becomes "stretched out". The opposite happens to the negative portion of the Glue waveform in this instance, so becomes condensed.

CV Lock between the three VCOs ties the exponential frequency bus of the Scissor oscillator to the two DNA VCOs. This is especially useful when using the OSC2 as a standard triple oscillator stack, as found in classic subtractive synthesizers. Sync Lock resets the Positive DNA to the positive portion of the Scissor VCO, and resets the Negative DNA to the negative portion of the Scissor VCO. There is also a switch in the Scissor section to shift the entirety of the OSC2 between low and audible frequency ranges.
