Polyplayground by MIGAMO (Mike Gao Mobile)

This app is great for the producer, composer, music theorist, and student. It makes understanding music theory easier, because the spaces are isomorphic, meaning that chords are the same in all keys. One only needs to learn a chord shape once to use it in any key.

The default 3:4 Balzano space has unique symmetrical properties that make it the ideal way to visualize and play harmony. The only drawback is step-wise motion, which has been addressed in the newest version of Polyplayground with Swipe Mode 3/4 (scalar swipe), as well as graphical cues for adjacent scalar notes.

This app has a sampler and synthesizer engine with separate pitch bend for each finger, but is designed to be used as a MIDI controller. For live performance, the app takes MIDI input, allowing you to visualize what a jam partner is playing. You can also stream chords you have already played into the device so that you are never lost if you want to improvise.

You can press the Horizontal/Vertical buttons to change your pitch space.
Guitar/bass players can use guitar mode, which changes the pitch space to a 5:1 (fourths by chromatic) for their familiar layout, while cello players can use 7:1 (fifths by chromatic).

What’s New

Version 3.85

Fixed bug that would get you stuck in harmonic minor for scale assist.
Swipe mode 5: swipe up and down for semitones, swipe left/right to get you back into the scale. Great for experimenting with some movements.

Hiasiiiii ,

Amazing sound, connecting to DAW hard

So Mike how do I connect this to ableton? The network midi doesnt work for me. Its a great app, great sound... Simply amazing.. Once it connects to a daw, im gonna take the game over lol.

It could be sooo much better!

This app has the potential to be a game changer for music creation. But...the integration with other midi app is HORRIBLE!! I have to EMAIL the chords to myself?? And then the midi files aren’t even recognized by my iOS daws. Why not just have an export option?? 🤦🏾‍♂️ At this stage in iOS music this just comes across as a dinosaur when you can’t integrate it with at LEAST AUV3 capability. It’s a midi controller that probably works great for a Bluetooth controller...but to add it my arsenal of iPad production tools, it needs some way to actually use it WITH other apps. I gave it two stars because it’s not completely useless...but it’s so frustrating to implement that it might as well be. There’s no help to understand the app at all from the developers. Which would be nice for something that basically one of a kind. I feel like I wasted my money....and I’m not happy about that. I can only pray they will update this app but at this point it looks like just a dud that coulda been a stud!

Can't give it stars if it won't work.

Yo the app looks dope and I'm sure it sounds dope once hooked up to a daw but I think you should really put a step by step of how you can connect it because for some reason I go thru the same steps I've seen on tutorials with 0 luck. I paid for this app and I can't get any response/advice from the developer. I know the app works for some but the fact that I can't get a response tells me customer service ain't part of this at all.
