Cš-L

Complex Oscillator

The Instruō Cš-L is a dual analogue oscillator optimised for generation of complex waveforms. It features two contrasting discrete circuit oscillators that are normalled to one another, offering a variety of simultaneous modulation routings. The resulting harmonic timbres sit far beyond the realms of traditional subtractive synthesis.

It expands upon the classic complex oscillator paradigm prominent in the West-coast synthesis philosophy. Typical cross modulation is expanded upon with inclusion of signal multiplication/amplitude modulation, a wavefolder per oscillator, final waveform symmetry biasing, classic and contemporary PWM, a global modulation index bus, and a digitally-controlled routing scheme that can be configured on-the-fly.

The two separate oscillator cores, simultaneous access to all included waveforms (both classic and contemporary), and the ability for bi-directional modulation, the Cš-L truly allows the user to shape sound like never before.
