Oscillators

A voltage controlled oscillator designed for generating complex waveforms. Expanding on the classic arrangement of Primary and Modulator Oscillators, the DPO has both of the VCOs operable as complex signal sources. It is in essence a Dual Primary Oscillator.Vintage voiced, all analogTriangle Core wi..

A compact Voltage Controlled Oscillator designed for generating SINE waves, Variable wave-SHAPEs, SUB-Octaves, Oscillator SYNC and Linear FM in the analog domain. The Sub-Timbral Oscillator is the more subtle and melodic friend to the DPO's complex harmonic lattice.Triangle Core with outputs for SIN..

​Dixie II+Full-featured triangle core VCO/LFOThe Dixie II+ is a larger variant of the classic Dixie II. Using the same great triangle core oscillator, it adds a number of features to make it even more versatile with only a modest increase in size. The Dixie II+ makes a great primary oscill..

Dr. Octature II4-pole low pass filter and octature sine wave VCO/LFOJust like the original Dr. Octature the basis of the module is a 4-pole lpf inspired by the classic “cascaded ota” design, but realized instead with superior-quality 2164 vcas.The sound is very reminiscent of classic ..

 Not long after David Dixon finished the Dixie design he began working on a totally novel approach to implementing TZFM, thru-zero frequency modulation. After almost a year of experimenting and many PCB revisions later we are pleased to present what is surely David’s masterpiece as far as analo..

100% Discrete Electronics. Instead of today’s popular surface mount ‘cell phone’ parts (smt), our modules use full sized resistors and capacitors that are hand inserted and measured with precision of 0,1 - 1 % accuracy, to deliver the very best audio quality. Industrial grey panel Space panel 1.Volt..

A-111-4 contains four precision VCOs and has individual controls, inputs and outputs for each VCO available as well as a common control and output unit. After all the A-111-4 is very similar to four A-111-3 without LFO mode but built in output mixers for the three waveforms, and a master u..

4 Operator FM‘Akemie’s Castle’ is a dual voltage controlled oscillator with authentic 4 Operator digital FM using ‘new-old-stock’ Yamaha IC’s for audio signal generation.Each of the 4 operators feature independent waveform selection, frequency multiplier and level control via direct panel operation ..

Erica Black VCO is analogue VCO with four simultaneous waveform outputs and one octave down suboscillator.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. Unlike harsh logic divide..

Full analogue VCOWhen we decided to expand the Pico series, we realized, we need more analogue designs. Therefore we give you Erica Pico VCO2 – powerful, full analogue VCO with great tracking over 8 octaves just in 3HP! Combine two of those, add some PWM and have a sound of real analogue b..
