Hex MIDI - Isomorphic Keyboard

Hex MIDI transforms your phone or tablet into a professional isomorphic keyboard.

Instead of traditional piano keys, Hex MIDI uses a geometric layout where chord shapes and scale patterns remain the exact same, no matter what musical key you are in. Learn a chord shape once, and play it anywhere!

Choose Your Perfect Layout:
- Switch instantly between the most popular isomorphic presets used by high-end hardware controllers:
- Wicki-Hayden: The industry standard for hexagonal playing. Perfect for fast scales and piano-like runs.
- Harmonic Table: The ultimate chord-building layout. Play major and minor triads with simple one-finger triangle shapes.
- Janko (Bosanquet): A linear, melodic layout for seamless playing.
- Fourths (Guitar): Tuned exactly like a guitar. Guitarists can apply their fretboard knowledge directly to the screen!

Powerful Features:
- Shape-Shifting Keys: Not just hexagons! Customize your grid to use - Hexagons, Squares or Circles to match your favorite playing style.
- MIDI Control: Connect to your favorite DAW or external synthesizers.
- Customizable Grid: Adjust the size of the hexagons to fit your screen and your hands perfectly.
