About Pentatone

"Beautiful, fun and inspiringly expressive" - The Arithmophone Pentatone is a music app featuring an easy to play pentatonic keyboard and a built-in synthesizer. Instead of using piano keys or a grid-based interface, Pentatone takes a fresh approach, optimised for the ergonomics of touchscreen devices and inspired by instruments like the kora and mbira. The app also has a sophisticated scale selection system that includes all the common pentatonic scale types and unlocks some more unusual ones.

*****

Pentatone features:
- An easy-to-play keyboard, split for two handed playing
- An original pentatonic scale system with 9 selectable scales, in just intonation or standard tuning
- A custom Audiokit-based synth engine (binaural 2x2 op FM with stereo detune, resonant filter, delay and reverb)
- 25 preset sounds with macro sliders for tone and ambience
- Initial touch and aftertouch response, both polyphonic

Pentatone is part of the Arithmophone project

Very usable sounds and the form factor is perfect for touch. Keyboard always feel awful so this is refreshing. Would LOVE to see this implemented into the android version of koala soon similar to ios. Great app.
