This oscillator is built on the classic circuit used in the 80s by Roland, Sequential and others.

Original CEM chips give us that silky smooth 80s feeling back again.
But one can chose to try out more modern ICs like the Alpha 3345-HYB
Unlike more vintage sound sources it will track just fine over 8 octaves..


Three standard waveforms can be mixed into one rich tone
It features an octave switch, a sub oscillator with dedicated CV (0-10V square) out , scalable FM and CV control and also attenuverted CV controlled PWM .
The FM is normalled to the sub oscillator to add even more grit to the sound

The h series modules require a h bracket to be mounted in a 1U space
