Dusu /// Analogue Oscillator

Double trouble!

Dusu is a voltage controlled oscillator with two sub-oscillators. It features a saw and a square wave. The latter has a pulse width modulation parameter and CV input. You can blend between both waveforms. The two sub-oscillators both have a volume parameter.

Carve /// Analogue Multimode Filter

Carve it out!

Carve is an analogue multimode filter based on the well known MS-20 (René Schmitz) design. It features a blend control between the low pass and high pass output. With full resonance, this filter can also be used as an oscillator (tracking 1V/Oct across four octaves).
