Simple application to test the speed of sending MIDI notes with velocity information over Bluetooth LE (BLE or Bluetooth Smart).

A small MIDI DIN plug with BLE transmitter draws it's power from the MIDI OUT jack.

The received data is displayed on a simple histogram style plot. The x-axis is the keynote. The y-axis is the velocity value indicating how hard the key was pressed.

I want to adopt the BLE MIDI protocol, but unfortunately the Simblee does not provide a means to declare the required custom characteristics. In order to do so, I have to use the Nordic SDK and/or the MBED compiler. Either way, I loose the Simblee For Mobile feature. Perhaps the easiest way is to use a RFDmbedMK20 to mate a RedBear MK20 MBED USB programmer to the Simblee JTAG pins.
