The MIDI Sight Reader Java Applet works again! To use it you should use Firefox with Java Applet Plug-in installed. Developed using Firefox 25.0.1 and Java 7, Update 51. So what is it? Well it scrolls random notes within a selected key, playing them aloud for audio confirmation, while you, the user, play the notes on your instrument.
There is no MIDI interface, the name refers to MIDI because it uses the Java Midi API and organizes everything numerically, according to MIDI numbers...
