The Subharmonic Oscillator is one of Serge's latest inventions and also one of his most extraordinary designs. 7 accurate analogue VCOs tied at the waist- in unison, yet their frequencies can open up like a fan, creating complex clusters. Each voice generates a pulse wave. It is temperature compensated and follows exceptional 1V / Octave tracking.

In addition, each voice provides (voltage controlled) pulse width modulation or subharmonic division as well as an individual output. The precision of these voices in combination with a global Spread control and various FM inputs opens up an enormous sonic range from massive unisono sounds to dissonant, orchestra-style textures.

The ODD and EVEN outputs enable the use as a stereo oscillator.
