Erica Synths Fusion VCO is special kind of VCO – it fuses great 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. If you wish to go really low frequencies and have a sound that sets your modular system apart from mass – this is exactly module, you need!

All Fusion modules by default are configured to work with regular eurorack PSU.

• 3 basic waveforms (sine, triangle and pulse) with VC morphing, for example, triangle morphs from sawtooth to ramp
• Good 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
