Zephyr is a 10hp single voice complex VCO based on the lovely SSI2130. Designed in honor of our daughter Zephyr Rose.
Zephyr is a bit of a mashup of the excellent trackability and octave switching found in the Spectrum VCO and the complex waveform generation of the Zero Point Oscillator along with some additional unique features to create a powerful analog VCO, including:
• 8 octave rotary switch
• Variable response TUNE control – FINE (1 octave), Coarse (7 octaves), and LFO (7octavess)
• Frequency range ~3.5Hz to 29kHz (Audio) ~8mHz to 70Hz (LFO)
• 0.3-0.6% THD dedicated SINE output. TRIANGLE and SAW outputs
• PWM Pulse output with two types of PWM – EDGE and CENTER
