Meet Vulcan, the flagship from Hampshire Electronics — a fully polyphonic, 100% analog Eurorack synthesizer that brings classic warmth and power to the modular world.With up to eight discrete analog voices (or a fat 4-voice mode with dual oscillators, sub-oscillators, and filters per voice), Vulcan gives you the flexibility to go from lush polyphony to powerful layered monosynth textures.Control it your way — via MIDI or eight independent CV/Gate inputs — and integrate seamlessly with the rest of your system. Each voice offers dedicated patch points for VCF, FM, and VCA, opening the door to deep modulation and complex sound design possibilities.Featuring three LFOs, two ADSR envelopes, and a beautifully responsive analog signal path, Vulcan combines the immediacy of modular with the depth of a true polysynth.Hand-built in England, the Vulcan is designed for musicians who want real analog tone — without giving up modern control or Eurorack integration.Vulcan Manual: Download Vulcan Manual PDFDemo: THIS Eurorack Can Play Chords! (Analog Poly Synth)Key FeaturesSwitchable 4-Voice / 8-Voice OperationChoose between lush 8-voice polyphony or powerful 4-voice dual-oscillator mode.4-Voice Mode: 2 oscillators, 2 sub-oscillators, and 2 filters per voice for a massive stacked sound.8-Voice Mode: 1 oscillator, 1 sub-oscillator, and 1 filter per voice for full polyphony.Dual Oscillator SectionEach oscillator has separate tuning, allowing thick detuning, FM tones, or perfect interval tuning.Controls include Level, Sub, Pulse Width, and Waveform selection (Triangle, Saw, Square, Tri/Saw blend).Flexible FilteringEach oscillator has its own filter and resonance, or they can be twinned by setting OSC2 level to zero to share a single filter path.Full Modulation Architecture3 LFOs with 12 destinations for advanced motion and timbral animation.Dedicated VCA envelope and VCF envelope with adjustable level control.FM, VCA, and VCF modulation per voice — normalled for easy patching, or isolated using the included GND jack.Presets & Performance Control99 programmable presets for instant recall.Presets can be stored globally or per-voice, allowing up to 8 independent sounds at once — perfect for layered or multi-timbral setups.MIDI and CV IntegrationTRS-A and TRS-B compatible MIDI input for easy DAW or controller connection.CV/Gate inputs per voice enable the Vulcan to function as eight separate mono synths or one cohesive polyphonic instrument.Blended output with master volume control.Sound & WorkflowThe Vulcan’s analog signal path delivers deep, rich harmonics and dynamic control. In 4-voice mode, its dual oscillators and filters create dense, evolving textures. Switch to 8-voice mode for lush pads, poly leads, and layered chords with precise tuning and per-voice modulation.Whether in a Eurorack system or standalone rig, the Vulcan bridges classic analog warmth with the flexibility of modern modular synthesis.SpecificationsFormat: Eurorack moduleWidth: 56HPVoices: 4 or 8 switchablePresets: 99LFOs: 3 (12 destinations)Envelopes: VCA + VCF (with level)Inputs: CV/Gate per voice, TRS-A/TRS-B MIDIOutputs: Blended audio with volumeConstruction: Hand-assembled in the UKIncludedHampshire Electronics Vulcan modulePower ribbon cable
