ChordPolyPad is a chords player for Midi instruments, sequencers like Logic, Cubase, Live and all other Midi sequencers, or even virtual instruments installed on the same iPad. The chords can be played live from pads.

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.

Velocity Detection is Useless


Could have been the ideal app but the only realtime velocity detection is worthless. To make it perfect make the accelerometer detection adjustable and offer the option of pad position velocity selection. I.E. top, bottom, left, right, for high velocity. Dare to be different - offer velocity options.

Powerhouse VirtualMIDI controller for chords, scales, and composition


The on-board synth sounds (about a dozen) aren't much, but this app excels at customization as a controller for other synths and MIDI compatible music apps. Not only is there a huge library of chords, but it recognizes and names chords as you combine notes on the keys. These chords (or single notes) can be mapped to individual pads, which are a great size on both iPad and iPhone. There's even additional x and y axis gestures for pitch and other effects. If you've ever used ThumbJam's control system, it's similar to that except you can put anything anywhere you need it. Long story short: it lets you control other music apps with dexterity and complexity that the apps themselves do not allow. It's not one of the cheapest virtual MIDI controllers, but it may be one of the best.

NOTE: Be sure to turn on "background" audio in the synth/music app you are controlling!
