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.

Nitpickin'Gamer ,

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.

Developer Response ,

You can just connect it via Audio/MIDI Settings with a cable connected and click Connect on iPad. Or use a MIDI / ipad interface OR use a free iPad Midi transmitting app like MidiLE/MidiMittr

Looks neat!

At only 15mb it looks well developed too.
