Reading data from the MIDI keyboard at iOS (and probably also at the Mac)

I’m just implementing support for the MIDI keyboard under iOS – mean you can connect MIDI keyboards (I’m using MIDITECH GARAGEKEY Mini) connected via the Apple iPad Camera Connection Kit.

The keyboard works perfect, you just plug it into the iPhone or iPad and it works. As the keyboard doesn’t have any additional led diode it has really low power consumption.

From the free software I found only GarageBand from Apple to be working with the keys.

At my application the keyboards can be easily implemented via the CoreMIDI (here is link to download my implementation for Delphi).

Here is how I handled them:
