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).
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.
Ratings and Reviews
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.
Had a very newbie understanding of how scales related to one another but this app has expanded my understanding of music theory all together
This app is really cool, it helps me understand how the music works without proper musical training. It's really easy to get into the zone and and just experiment with different combinations of sounds. Mike Gao finally fixed the issues with the synths on ios8 so now you can use this app standalone.
You can also hook up this app to Ableton (and other DAWs that work with network midi). I am going to make a video how to do that soon, you should be able to find it by googling polyplayground ableton setup.
With Family Sharing set up, up to six family members can use this app.
