Compact and self-contained, TEIÚ is Reco-Synth's analog modular entry point: a small patchable system meant to give players the core building blocks of subtractive synthesis in one instrument.
The official manual describes two 3340 oscillators with volt-per-octave inputs, a white-noise generator, an LFO with fast and slow ranges, a 24dB/oct 3320 low-pass filter with mixer, two AR envelope generators, and a VCA. Banana patch points, CV/gate inputs, and a 1/4-inch audio output make it feel closer to a compact modular system than a conventional desktop synth.
That architecture is enough for basses, leads, synced oscillator sounds, noise textures, filtered wind effects, percussive patches, and LFO-driven robotic patterns, all without depending on MIDI, presets, or a hidden digital engine.
