This is not a set it and forget it oscillator. It’s an oscillator that demands to be tweaked, modulated and explored. It’s an oscillator that’s proudly analog and eschews all shortcuts. As such, it’s an oscillator that rewards you with sounds as boundless as your creativity.
Rubicon2 is a flexible, feature-rich, completely analog oscillator ready to scream or sing to meet the demands of your patch and the desires of your imagination.
It features nine simultaneously available waveshape outputs; two sub-oscillators; three variations of a sine wave; a new Tri-State pulse circuit; exponential Frequency Modulation (FM); linear FM; hard and soft (flip) sync; pulse width modulation; CV control of FM index; a new foldable Warp circuit; and the ability to perform perfectly-symmetrical Thru-zero FM with no change in pitch or tracking accuracy.
Rubicon2 is the second generation of the classic Rubicon triangle core analog VCO, designed in collaboration with David G. Dixon.
Nine simultaneous waveform outputs (3 Sine types, Triangle, Saw, Double Saw, Zig-Zag, Pulse, Tri-State Pulse, Sub, and Warp).
Quick, accurate tuning via an 8-Octave switch, Pitch knob, LFO/VCO range switch, and front panel trimmer.
Lock switch toggles symmetrical Thru-Zero Linear FM with stable pitch tracking.
Wavefolding Warp Circuit blends a signal with the unique Tri-State Pulse wave.
Polivoks VCF is famous for its’ crazy resonance sweeps and deep, bassy sound which makes it ideal for acid basslines.
We believe, this is one of most is one of most authentic sounding famous Russian synth Polivoks VCF emulations available. The original Russian ICs K140UD12 are used in the sound circuit. We did several updates to adapt the VCF for contemporary modular synth demands. Independently buffered inputs, extended Cutoff knob range, eliminated clicks, when switching filter modes, and output stage added to eliminate signal inversion.
The Malekko/Richter Oscillator II is a great-sounding, solid analog Oscillator/LFO with some serious tricks up its sleeve. Fine and Coarse frequency controls are provided. Volt per octave and exponential (with attenuator) CV frequency inputs are provided. An output for each waveform is provided (Sine/Triangle/Square/Saw). A second series of outputs are provided for phase-modulated versions of the Triangle, Square, and Saw waveforms.
The SWAMP is a random CV and audio generator inspired by the famous Wiard Wogglebug module; it’s often the heart of self-generating patches and brings controllable randomness to your modular system.
In the SWAMP module we introduced numerous modifications and improvements to extend potentiometer range, added an audio input, which, when connected, replaces the internal Tone oscillator, replaced the expensive dual vactrol, built S&H circuit around the made in Riga S&H IC AS1100CK2, added audio waveform selection switches, CV output configuration jumpers and much more.
Three random audio frequency outputs
External audio input routed to ring modulator
Three random CV outputs
Clock input and output to sync the module to your modular system
CV control over internal clock for even more extreme randomness
The core of the VCO is borrowed from famous Russian synth Polivoks VCO and in exponential converter we use the original matched transistor IC that was used in Polivoks. But there are significant updated schematics to have the most out of your modular setup.
