Horst MWT-01 Midi Wave Theremin

Crafted in Melbourne around 2010, this hybrid gem fuses the ethereal glide of a stereo theremin with MIDI control and a punchy analog-style mini-synth engine, letting you summon waves without touching a key.

At its core, subtractive synthesis drives three monophonic voices through a classic 24dB/octave ladder filter, paired with tremolo, auto-trigger, gate, and envelope follower effects for dynamic, responsive sound shaping. MIDI in and out make it a versatile controller, while internal flash memory stores your patches for instant recall. Controls blend theremin antennas for pitch and volume with tactile knobs and switches in a compact, road-ready chassis—perfect for experimental setups that demand both touchless expression and hands-on tweaks.

Over the years, players have praised its unique stereo theremin fidelity and hybrid warmth, calling it a cult favorite for ambient and avant-garde rigs, though some note its monophonic limit keeps things focused rather than expansive. If you're chasing that otherworldly vibe with modern connectivity, it's a rare find worth hunting down.
