  1. 5/5Absolutely Genius

    In short summary, you’ll find that this app unapologetically turns your iPhone into an instrument. This isn’t some full blown DAW, nor is it just some bad excuse for a keyboard/synth app. I’ve only been using it for 10 minutes and felt compelled to write this. Within about 30 seconds of using the app, you’ll see just how genius this all is. Don’t get me wrong, Garage Band and other iOS DAWs can be fun, but sometimes they lack the simplicity to just jam. Then other apps can be easy, but too simple and too canned. This app just has some amazing, perfect balance to it where it doesn’t try to be anything that it’s not, while still having options and controls that largely improve quality of life. Completely worth $8, in fact, I might pick up an old iPhone for the sole purpose of dedicating it to this app. There’s also MIDI out (at least I assume it’s MIDI out, but even if it’s just MIDI, that’s cool too) through I don’t have a Lightning to MIDI adapter (which I assume assume must exist), perhaps something I’ll look into in the near future. If there was any reason to seriously pursue iOS MIDI, it’s this. Also, not sure if this can be used on an iPad or not (whether natively or the iPad running it as an iOS app)— that’s something I’ll also be looking into. One last comment: I did notice the app crashes if you’re attempting to use the record feature for creating a sampled voice. Though it only seems to crash if you tap the button. If you hold the button down (which you need to anyway to record it), it’ll work as intended. Just a tiny scratch that can easily buff out on an otherwise perfectly functioning machine. If the developer is reading this, all I want to say is thank you. Thank you, thank you, thank you.

  2. 5/5Amazing Design!!

    This is such a darling little synthesizer, I am in love with all the dreamy little sounds it makes. I thought the controls were confusing at first but after reading the tutorial and using them for a few minutes I was able to really quickly get the hang of it and it feels super intuitive now and easy to access as Im playing. The only thing I could want from this is a way to switch from seeing the standard plectrum to one where I can visually distinguish each individual “button” so I could play them individually a bit easier if I wanted, but its amazing either way :)!

  3. 5/5A blast to just make chill jams with.

    When I heard a Suzuki Omnichord in a few songs I went nearly mad trying to find ways to recreate the sound in GarageBand. This app hits that vibe right out the box and even does (in my opinion) a better guitar than in GarageBand. Honestly, the one feature I would love to see is support in GarageBand so I could easily slot this perfect instrument into my workflow. For now I have to use an app called Polychord, which while nice, doesn’t scratch that omnichord itch like this app.

  4. 5/5Best app Ever!! - Only one thing I dislike

    Ever since ive heard the sound of an omnichord i loved it and knew i wanted one to get those amazing sounds and tomes, I was dissapointed to find how expensive they were. This app is so much fun and only 5$ especially for musicians. This is a really underrated tool for musicians to use it can really inspire you to make make cool music and add a whole new dimension to your music. 5 stars AMAZING !!!! Feedback to developers: The only thing i dislike is that when you turn on auto-chord and hold on, the E chord is an extremely low octave and sounds muddled, and on the official app trailer it shows a large E on the notes grid but on the app it apears much smaller. I would love to have the E chord an octave up or so, at least an option to do so. I thank any developers who take the time to read or fix this. Thank you!! I love ur app!!

  5. 5/5Great for audio professionals, omnichord enthusiasts, tinkerers, and everyone in between.

    I love that classic omnichord sound, and I love how fun it is to noodle around with this app. As a music hobbyist, this has been extremely helpful in dissecting and learnjng chord progressions, following along easily with guitar/piano tabs, and writing my own music. All on the go during my daily commute. Can’t recommend enough, have also bought as a gift!

    some minor fixes hope this will help with sample recording crashes. *I remind you that to record a sample you need to hold on your finger for a while (you'll see a little screen pop-in with waveforms).

    *FIXES* After sooo much time finally a fix. Record button has been restored. And also the "mic" button. (Almost forgot how cool it was for a songwriter.) Here is how you should use it: For "normal" recording: Open the panel and just press the "REC" button, wait 3 seconds (you'll se a little countdown) and you can start play. When you're done, open the panel again and click on it another time (the REC button). Now you can listen back to it (in loop) and SAVE it (the yellow and the blue button). *When you're saving it, you can decide to send it directly to someone else or store it. For "MIC" button: To add your vocals you have to PLUG IN the earphones AFTER the app has opened. Ye, little weird I know. Now you can open the panel and click on MIC (in the bottom-right). You should hear your voice back in the earphones. (If it does not work, unplug and plug them back again until you see MIC button keeps in selected position). If it is working you can use as it is (to rehearse or wherever) or record it over your playing. Thanks again for your appreciation over the months.

    for smaller devices, the panel can now be closed in the left-bottom (there's a close label). other fixes like some user suggested, on ui glitches. some improvements on right plectrum zone which could cause some glitches too (like changing note order when swiping on some devices).

    some users experienced some crashes on iOS 17.x we patched that. however, for those devices running that version, we do not guarantee the correct working of the midi-over-bluetooth feature, based on some os' restrictions. we also patched a bug we found on the sequencer. thanks.
