JFugue 2. Play Notes

This program will play a note in the range from MIDI_START to MIDI_STOP, each time the Play button is clicked.

The play button will have the text for the next note to be played. The program will keep on recycling between MIDI_START and MIDI_STOP.

This is the output after MIDI_STOP has been reached and the program has recycled back to MIDI_START:
