Hex MIDI
Read full descriptionHide 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 β Classic concertina layout with fifths/fourths diagonals and octave columns. β’ JankΓ³ (Classic & Vertical) β Whole-tone rows with uniform chord fingerings. β’ Harmonic Table β Euler's Tonnetz grid: major/minor third diagonals with vertical fifths for visual chord building. β’ Bosanquet-Wilson (Maupin) β Generalized flat-top hex layout built for microtonal navigation. β’ Harpejji β Whole-tone string layout with semitone vertical progression. β’ Chromatic Button Accordion β Authentic C-System and B-System (Bayan) layouts. β’ Fourths & Fifths β String instrument tunings for guitarists, bassists, and violinists. β’ Major Thirds & Diminished Harmonica β Symmetrical grid layouts. β’ Custom Layout Editor β 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.

Verdict
The clearest difference is in-app purchases: LoopInk at none against Hex MIDI's 1. LoopInk also leads on update cadence (weekly vs monthly). Hex MIDI's advantage is ads (none vs shown). On price, device support and iOS requirement there is nothing between them.
