At present not all the features that I originally intended to implement are complete, I welcome anyone that is interested in this project to get in contact with me. If you would like to look at my source code or think you can help me develop areas of this application further then please do not hesitate to contact me.

The report for this project can be downloaded here

Features:

  • Developed using the Java Sound API and the NetBeans IDE
  • GUI developed using java Swing Components
  • Compatible with M-Audio’s X-Session pro DJ MIDI controller
  • Audio playback speed control using cubic interpolation
  • VU meters to display audio signal volume
  • Volume and gain control
  • Graphical display of audio signals wave form

It then uses these MIDI messages to generate sine waves, square waves and sawtooth waves on the fly. The pitch of sound is dependent on the Midi message.

The application requests the user to chose an input midi device, once the device is connected you can play the keyboard and the application will generate sound. The application will close if no MIDI device is selected.

The application requests the user to chose an input midi device, once the device is connected it then displays the Midi messages via a GUI. The application will close if no MIDI device is selected.
