Thejasvi Magudilu Vijayaraj / Mbed 2 deprecated MIDI_Synthesizer

This is a MIDI synthesizer with touchpads used for playing the notes. mbed will capture the touchpad press and release events and sends the appropriate MIDI commands to the PC. By using the C# windows forms application created by us, one can compose songs as though they were composed on a piano. We support all types of standard MIDI piano types.

Dependencies: mbed
