Hex MIDI

Features
Read full description

Hex MIDI is an isomorphic MIDI controller and microtonal synthesizer. Instead of the standard piano keyboard, notes are arranged in geometric hexagonal grids - meaning chord shapes, scales, and intervals remain identical across every key. Whether you want to play alternative keyboards like the Wicki-Hayden or JankΓ³, compose in 19-EDO / 31-EDO microtonal tunings, or control your DAW over MIDI and MPE, Hex MIDI gives you the tools to explore harmony through geometry. Built-In Keyboard Layouts: β€’ Wicki-Hayden – Classic concertina layout with fifths/fourths diagonals and octave columns. β€’ JankΓ³ (Classic & Vertical) – Whole-tone rows with uniform chord fingerings. β€’ Harmonic Table – Euler's Tonnetz grid: major/minor third diagonals with vertical fifths for visual chord building. β€’ Bosanquet-Wilson (Maupin) – Generalized flat-top hex layout built for microtonal navigation. β€’ Harpejji – Whole-tone string layout with semitone vertical progression. β€’ Chromatic Button Accordion – Authentic C-System and B-System (Bayan) layouts. β€’ Fourths & Fifths – String instrument tunings for guitarists, bassists, and violinists. β€’ Major Thirds & Diminished Harmonica – Symmetrical grid layouts. β€’ Custom Layout Editor – Build and save your own hexagonal or rectangular grids. Microtonal & Tuning Engine: β€’ EDO Presets: 19-EDO, 22-EDO (Shruti), 24-EDO (Quarter-tone / Maqam), 31-EDO (Meantone), 41-EDO, 53-EDO, and sub-12 tunings (5-EDO Slendro, 7-EDO, 10-EDO). β€’ Scale Formats: Bohlen-Pierce (13-EDT), Just Intonation, and custom scale generation. β€’ Scala Support: Import standard .scl tuning files and .kbm keyboard mappings. β€’ Visual Color Modes: 5ths spiral color coding, Tonnetz harmonic spectrum, and minimal two-tone palettes. β€’ Note Labels: Display note names with arrow accidentals, SolfΓ¨ge, interval numbers, or exact Hz. MIDI & Expressive Performance: β€’ MIDI I/O: Connect via USB MIDI to hardware synthesizers, external keyboards, and DAWs (Ableton, Logic, Reaper, Bitwig). β€’ MPE & Vibrato: Per-note microtonal pitch-bend routing and touch vibrato. β€’ MTS Support: Real-time MIDI Tuning Standard SysEx transmission for compatible synths. β€’ Touch Control Pads: Integrated dual X/Y pads for assignable pitch, modulation, and CC filters. β€’ Built-In Sound Engine: High-fidelity soundfont player with instant response.
