Five voices

Piano, Fantasy, Violin, Flute and Guitar: five lo-fi characters, each built from a 1-bit pulse. And one voice you program.

Verified for version 1.1.0 · Updated October 17, 2026

Slide TONE to pick a voice. There are no samples in PocketTone: every voice is a 1-bit pulse wave with its own shape and its own envelope, the way the early-80s calculator-synths made sound.

Locked voices

Slide to a Pro voice without Pro and the unlock sheet opens. Close it without buying and TONE goes back to the voice you had.

In calculator mode

With POWER on CAL, every voice is replaced by the calculator's own beep: a buzzy, pulsing square. Flip back to ON and your voice returns.
