Erica Synths tells us that their Fusion Drone System is a tube-based eurorack modular synth designed for raw, esoteric soundscapes. It can be seen in the video above. They say that modules including two key modules – Fusion VCO and Fusion Delay/Flanger/Vintage - are already available and will be shipped after August 22nd. Here's the details in their own words...

Fusion VCO is absolutely new Erica Synth Fusion line module which 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

Erica Synths Fusion Delay/Flanger/Vintage Ensemble module is distinct multifunctional analogue effects module that combines BBD chip based effects with an adjustable tube overdrive in the delay output and feedback path for extra thickness of sound. For more flexibility, lowpass filtering is fully adjustable from none to extreme. Special feature, not found in eurorack, is Vintage Stereo Ensemble – effect that's common on vintage synthesizers to create moving and thick spatial sound from a monaural tone generator, be it VCO, FM, DCO or any other kind. Such spatial effect is achieved by mixing dry source with delayed and lowpass filtered out of phase signal.

Main features:

2 BBD chips (1024 and 4096 stages)
Delay and Flanger effects
Vintage Ensemble Stereo effect
Tube overdrive in the delay output and feedback path
Dry/Wet mixing
Passive Lowpass filter for extreme subbass sound
