MIDI Host

[huttokd]

Sorry if this is obvious but does this code work for using the Arduino as a host? I want to connect the Arduino to a MIDI keyboard to control various things based on certain keys being pressed. I have an Arduino Leonardo but have seemingly been unable to receive anything from the keyboard using the example codes.

This lib relies heavily on MIDIUSB and is based on PluggableUSB. Check these libs for your basic functional requirements.

Leonardo should work fine to receive MIDI messages from your MIDI keyboard.
