About

Gradatone

Features
Read full description

Gradatone is a seamless pitch instrument: swipe the screen and hear pitch move smoothlyβ€”named for the gradient of sound. Play with nuance keyboards cannot easily offerβ€”vocal-like vibrato and string-like glissandos. Layer timbres for rich harmony, or turn on Snap to pull pitch gently toward a scale. Choose from major, minor, Okinawan and Miyako modes, Chinese pentatonic, Indian (raga), Arabic, blues, and more. Labels include English, kana, and Indian note names (Sa/Pa). No account, ads, in-app purchases, or tracking. Settings stay on your device only. On iOS, you can play even when the Ring/Silent switch is on (use the device volume buttons).
