ctal

Eight buttons, endless music.

Octal's bead in its dial beside the eight buttons, one of them lit

A pocket synthesizer for iPhone. Eight buttons each play a chord that fits, and a bead under your other thumb bends the sound as you play. Record a loop, layer another instrument, and you have a track in minutes. No theory, no lessons. Just play.

On iPhone Duo, open the phone and Octal becomes a loop station: the chord pad on one half, your tracks and instruments on the other.
