Octal: Pocket Synth
Eight buttons, endless music
Only for iPhone
Free · In‑App Purchases
iPhone
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: a verse, a chorus, an ending.
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.
- The Loop Deck: Swipe along the strip and your buttons melt into your loop, lane by lane and bar by bar. Tap a bar to mute it, hold a lane's number to solo it, and move, copy or clear bars as it plays. Loops can be 1 to 8 bars long, in 3/4, 6/8, 7/8 and more.
- Songs: Pinch the Loop Deck and your loops line up as blocks in a song. Drag loops in from the shelf, choose how many times each plays, fade them in and out, and tap a block to jump to it while the song plays.
- Voicing beads: Pinch a chord's buttons and they shrink into beads. Push one up, down, left or right to play the chord higher, lower, deep or wide.
- And a long list of fixes and polish.
