"ChordPolyPad" is a MIDI chords player that allows you to create chord sets from a large internal library, from any combination of notes, or from chords generated randomly. Each set consists of 8 groups of 16 pads, or 2 groups of 64 pads. In addition to play chords, each pad can generate customizable MIDI controls on its horizontal and vertical axis.

It can be used as a standalone application or an Audio Unit MIDI effect plug-in.

The application supports full internal and external MIDI connections for input and output. An internal sound bank is included.

The Audio Unit MIDI effect plug-in supports multiple instances. A compatible host is required to run the plug-in. The host needs to support the Audio Unit MIDI effect format.

Excellent tool

I have enjoyed this app for years, and it continues to be one of the most useful tools I have for composing and studying chord progressions and voicings when away from a piano keyboard. Use it with the built in sounds for convenience, as a controller for other iOS music apps, or combine this app with the musicIO MIDI app, and a wired connection from iPhone or iPad provides a rock-solid, low-latency connection for chord input to your computer's DAW. MIDI over WiFi is also possible.

The developer is accessible by email and is very responsive to bug reports—hence the recent update with a minor bug fix. The app has received many updates and improvements over time. Well worth the price.

Change of heart.

I originally gave this 1 star since it was not recording the midi into beatmaker 3. I reached out to the dev and was advised on how to get it going. Now it works
“ Beatmaker 3 does not record the MIDI from AUv3 MIDI effects. You need to use Beatmaker 3 virtual keyboard to trigger ChordPolyPad, then it will record the notes played by its own keyboard that will trigger ChordPolyPad. This is not a limitation of ChordPolyPad, but a limitation of Beatmaker 3.”

Best chord app yet

I've tried a plethora of chord and scale apps. None of them has the versatility of this one. The only thing that holds me back from 5 stars is the ability to play the single notes of a chord. It would be great if there was a switch on the chord note keyboard that would change it to the keys of the note of the chord selected.
Chordion has that feature but this app, which I just bought because Chordion 2 hasn't come about, is still much better than Chordion. Love the app and some of the internal sounds are pretty darn good!
