Fusion VCO

VCO with two vacuum tube based suboscialltors

Fusion VCO fuses good tuning of digital VCO with warm, unique sound of vacuum tubes that work in suboscillator circuit. Two double triodes in bistable latch connection act as suboscillators: -1 and -2 octaves with plenty of mixing opportunities for amazing sonic results. External audio signal can replace internal VCO. It’s exactly what you need, if you wish to go really low frequencies and have a sound that sets your modular system apart from mass!
Main features:
•3 basic waveforms (sine, triangle and pulse) with VC morphing, for example, triangle morphs from sawtooth to ramp
•1V/oct tuning for 8 octaves
•Vacuum tube based suboscillators -1 and -2 oct
•Manual and CV controlled -1/-2 oct mixing
•Adjustable suboscillator waveshape
•Dry/Wet (VCO/suboscillators) mixing
•Passive Lowpass filter for extreme subbass sound
• Audio input
