SSF Steady State Fate ZEPHYR Eurorack Thru Zero Phase Mod Analog Oscillator Module

Zephyr is a 10hp single voice complex VCO based on the lovely SSI2130. Designed in honor of Andrew's daughter Zephyr Rose.

Zephyr is a bit of a mashup of the excellent stability, tight and extended tracking, and octave switch found in the Spectrum VCO - a full featured analog oscillator - and the complex waveform generation of the Zero Point Oscillator, along with some additional unique features to create a powerful analog VCO such as analog phase mod!  Features include:

• 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)

• 3-0.6& THD dedicated SINE output. TRIANGLE and SAW outputs

• PWM Pulse output with two types of PWM – EDGE and CENTER

• 1 or 2 octave SUB out – also affected by PWM control and type

• Voltage controlled Z-WAVE output mixes a VC wave folding and overdriven SINE with the PWM pulse

• Dedicated normal FM input with attenuator. Can be AC coupled linear or DC coupled exponential response

• Hard Sync with universal response to any waveform input

• Multi-mode ZMOD input with attenuator and INDEX VCA CV input. Modulation depth Index up to 1.5

• ZMOD modes include true Through-Zero Phase Modulation, ZYNC (hybrid reversing sync with linear TZPM), and FLIP (hard waveform reversal)

Analog Phase mod is great sounding and incredibly fun!  It has a similar feel to FM while preserving pitch (and not going sharp) with heavy depth.
