Steady State Fate Zero Point Oscillator

Analog Morphing Thru-Zero Oscillator with 8 Waveforms

16 HP Eurorack module

The SSF Zero Point Oscillator is a premium analog VCO featuring true thru-zero linear FM, dual waveshapers (A and B) with morphing, 8 simultaneous waveform outputs, sub-octave generator, and LFO mode. Its signature feature is the Zero Point control that adjusts the null point of thru-zero FM for DX7-style timbres.
