Octal turns your phone into an instrument. The eight buttons play chords or notes that always go together, so whatever you press sounds like music. The bead under your other thumb changes their mood or behavior as you play. MAKE A LOOP Press record and play a few bars. Open the wheel, pick drums or a bass, and play over the top. Swipe over to the Loop Deck to see your loop and change it bar by bar. TURN LOOPS INTO A SONG Pinch the Loop Deck and chain your loops into a song. SOUNDS Synths, keys, drum kits, textures and acoustic instruments, a tap away on the wheel. NEVER LOSE AN EDIT Every edit is kept. The history tool lets you wind back to any of them. SHARE IT Send the mix as an audio file, or send the loop or song itself to a friend who has Octal. Making music in Octal is free, with four saved loops and one song. THE FULL VERSION One purchase, no subscription. MIDI and stems to finish your song in a DAW, MIDI out to play other synths, the bead lab to make and keep sounds of your own, and as many loops and songs as you like. PRIVACY Octal collects no data. The microphone is only on while you record a sound or play a Vocoder.
