The Waveforms Oscillator from Pittsburgh Modular is a wide-range, high-quality complex voltage-controlled oscillator (VCO) that is designed to be the core of a modern, analog Eurorack modular synthesizer. The Waveforms module offers a full complement of standard waveforms including sine, triangle, saw, and pulse, as well as a sub-octave generator and a unique modulatable blade wave, which generates a saw wave one octave above the core frequency and creates a living, breathing, and evolving waveform that is still capable of tracking 1V per octave.
The oscillator provides 5 octaves of 1V-per-octave tracking and a frequency range starting as low as 7 seconds per cycle, allowing it to double as an LFO. Additional features include oscillator reset for hard sync, attenuated linear or exponential FM input, pulse width, and a pulse-width CV input. The Waveforms module is 10hp wide, 1.4" / 36.5mm deep and requires 25mA of power. The module ships with a ribbon cable.
