Living Manual

It’s like a live manual on caffeine! You can pick a model (PO or EP), and voilà—you’re greeted by a working representation of the device, like a digital butler. Hit the Fx button on the PO diagram in the app, and suddenly the button texts get a makeover with the names of the effects. Can’t remember which button combo copies your current pattern on a PO? Join the club! Just smash the Write button on the diagram, and watch the Pattern button transform into “Copy Pattern,” along with any other buttons feeling jealous, like the A and B knobs. This living manual is a chameleon; if you poke the Chords button on the PO Arcade, it proudly displays the chord names on all the buttons, like a proud parent showing off their child’s report card. The EPs play along too! Oh, and don’t worry; there’s a helpful tidbit about syncing with other models when you first pick a model, because who doesn’t need a little guide on how to get all their gadgets to play nice?

Song Editor

Ever tried to whip up a whole song but find yourself scratching your head, wondering which part is the intro, verse, or chorus? Trust me, I’ve been there, too! That’s why I whipped up this app—because if I had a dollar for every time I forgot my own song structure, I’d have enough to hire a butler just to remind me! In this delightful app, you can create your projects and name your sections, like “Verse1,” “Chorus,” or even go rogue with a custom label like “My Totally Amazing Section.” Then, assign a pattern/sequence for a PO or a scene for an EP and stash that in your project. The best part? You can drag and drop your sections like you’re a DJ at a party, arranging your song like it’s a game of musical Tetris. And when you’re ready to show off your masterpiece, just hit “Play” on the PO or EP diagram to witness the glorious chaos of your song order!

Also, store your data syncs from your PO (“3” series only) within a project. Record directly in the app and playback to your PO to reload your project. You may need an audio interface like the EP-136 KO Sidekick (works great with this app). Or you can upload a successful data sync audio file to your project. (Recording directly from into the app to create a good data sync works great in iOS, not so great in android, but playback from either works great!)
