Cš-L is a dual voltage controlled oscillator.
It takes the modern approach of dual primary oscillators and expands upon them.
Each oscillator sports its own wavefolder, PWM output and wide range of classic waveforms.
A four-quadrant multiplier stage allows for ring modulation as well as rectified and positive only amplitude modulation.
Each oscillator uses a different core (top sawtooth core, bottom triangle core) giving the best of both worlds. 
A versatile, definable routing modulation bus allows for CV control over a huge range of cross modulation without even needing to insert a patch cable.
