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.

天才之作

非常感谢mike gao制作了这个app,相见恨晚。一直很喜欢你的音乐。不过好像确实有点久没更新,有时候会有bug,很期待能有更新。期待加入auv3以及mpe。

Clearer explanation of all functions needed.

Decent app, especially for the price point.
Could use updating in terms of video tutorials on usage; the UI & general functionality is interesting but again needs a more structured tutorial guide, especially for the scales grid, ratios etc.
Dedicating an easy-to-digest YouTube channel with a good number of video tutes might be a good way to go.

Good but not excellent

I love the idea, is my fav midi keyboard, and i sold my other physical midis for this app
- can i connect via usb midi? Is so hard (maybe usb c easy connection?)
- bug when u connect urs EarPods
- echo, reverb FX just for make a idea

Auv3 update request

Great app However it would be a 5 star if it was updated to be an auv3 app. Being auv3 would absolutely fit this apps style and workflow for composition. It seems like a given. The current workflow stops me from using it unfortunately: since it’s so tedious compared to other compositional apps which can be used directly within the GarageBand, logic and others daws as a virtual instrument. I want to be able to work immediately with ideas from polyplayground rather than having to stop start since it’s such a visual app. If this was fixed then it would easily be in my top 3 MIDI tools.
