Project Demonstration1. An ability to poll an array of pushbuttons to manipulate

the musical configuration and display a visual pattern using LEDs.

2. An ability to output multi-tone audio.

3. An ability to adjust the volume and BPM of the output audio.

4. An ability to save and load musical configurations to and from flash memory.

5. An ability to save a configuration as a MIDI file to an SD card.
