“This is my version of a cluster generator. Clusters are part of the contemporary music arsenal of effects. The swarm has a total, tracking, V/octave range that is the same as all our VCOs, however, it outputs only pulse waves. Pulse-width operates from instantaneous -> square wave > 1st sub-harmonic > 2nd sub-harmonic …> Nth sub-harmonic. You guessed it, this is one VCO that sounds like a symphony orchestra playing Atmosphères by György Ligeti.”
Serge Tcherepnin, 18 October 2023
The Subharmonic Oscillator is one of Serge’s latest inventions and also one of his most extraordinary designs. 7 accurate analog 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.
