An isomorphic keyboard for microtonal music. Play any tuning with
the built-in sampler, or drive select capable synths with microtonal pitch.
Hexatone is an isomorphic hexagonal keyboard and microtonal instrument for iPad. Every interval
keeps the same shape anywhere on the grid, so scales and chords are easy to learn and transpose,
in any tuning. It makes its own sound, in tune, with built-in voices and a sampler, and no extra
apps required.
PLAY ANY TUNING
- Any equal temperament (N-EDO): 12, 19, 22, 24, 31, 53 and beyond
- Import your own scales as Scala (.scl) files, and keys show their ratios
- Manage your imported scales, and adjust octave, concert pitch (A4), and key density
A SOUND OF ITS OWN
- Two built-in voices that play in tune out of the box: a struck bell and a sustaining glass tone
- Load a single audio file and play it across the whole board, perfectly in tune
- Or import full multisample instruments (SFZ), as a folder or a .zip: pianos, kalimbas, pads, anything
- Name, rename, and manage your instrument library, and reclaim space, right in the app
- Choose how many voices play at once
- No external synth needed, though you can still send MIDI at the same time
PLAY HANDS-FREE
- Hold mode sustains a chord after you lift your fingers, so you can layer and let it ring
- Tap a held key to drop it; turn Hold off to release everything
ISOMORPHIC LAYOUTS
- Bosanquet, Wicki-Hayden, Harmonic Table, Fourths, Accordion, or a Custom layout
BEAUTIFUL, READABLE KEYS
- Glassy, glowing keys that light up as you play
- Four colour palettes (Pastel, Inferno, Turquoise, Campfire). Hue shows pitch class and
brightness shows octave, so you can read the keyboard at a glance
WORKS EVERYWHERE
- Standalone, or as an AUv3 plugin in AUM, Logic Pro, GarageBand, Cubasis, Loopy Pro, Drambo
- MPE pitch: each note plays on its own channel with its own pitch bend, so MPE-capable synths
sound every microtonal interval in tune
- Note velocity, a velocity curve, and an adjustable pitch-bend range
A note on MPE: Hexatone uses MPE for per-note microtonal pitch (the X axis). It does not
send the continuous Y (CC74 timbre) or Z (pressure) expression of touch controllers like the
Seaboard, because a flat screen has no native way to sense those. It is a microtonal playing and
routing instrument first.
What is new in 1.2.1
- Hold mode. A Hold button lets you build a chord and let go: it keeps sounding, hands-free. Tap a held key to drop it; turn Hold off to release everything.
Voices control. A slider sets how many notes the built-in instrument plays at once, and how many Hold can sustain.
- Instrument naming and rename. Imported instruments take the name of the file or folder you imported, and you can rename any of them. Older imports update to their real name automatically.
- Import a .zip. The multisample importer now accepts a folder or a .zip, including the ready-to-import .zip from the free SFZ Builder web tool.
Scale manager. A new screen to see and delete the Scala (.scl) scales you have imported.
- Built-in instrument voices. Two generative, in-tune voices out of the box: Hexatone Bell (a struck, bell-like tone) and Hexatone Glass (a sustaining, glassy tone that holds for as long as you want). No import or external synth needed.
- Fixes and polish, including cleaner high notes on the built-in sustaining voice and more reliable instrument import.
