Oscar DSF is a complex, stereo Voltage Controlled Oscillator, based on the mathematics of Discrete Summation Formulae.
The Discrete Summation Formula used in Oscar DSF produces sounds rich in harmonics (or ‘partials’) in a similar way to FM.
The mathematics of DSFs is more complex than FM, but the way that you, the user, get the sounds you want is usually simpler. The basic sound is controlled by just two, intuitive knobs (with CVs, of course).
Oscar DSF can sound like a traditional oscillator, and it can make the usual clangs and tings associated with FM oscillators. It can handle fat bass sounds, or evolving ambient drones.
Oscar DSF has two complete DSF based, complex oscillators, controlled by the same basic pitch CV, but with a pitch offset control which can detune one oscillator up to ±1 octave.
The output of the each oscillator passes through another complex FM stage, which acts like a wave folder, so that’s what we call it. Technically, it’s actually an FM operator with the carrier frequency set to zero. It sounds great, whatever you call it.
The final piece of the signal chain is a simple VCA, allowing Oscar DSF to be used as a stand alone synth voice with the addition of an envelope generator, or some other source of modulation.
