video upload by Arithmophone

"The Arithmophone Pentatone is a new iOS music app featuring an easy-to-play pentatonic keyboard and a built-in synthesizer."

"Pentatone is available now in the Apple App Store, for iPhones and iPads running iOS 15 or above.

The app is completely free (no in app purchases, no ads or tracking).

Most iOS music apps either give you 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. It 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 operator 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
