...yet another MIDI player...

This tool (and writing it) helped me to understand how music functions.

I have put this little project under GPL so maybe others can profit from it. The metronome is especially usefull to play with and maybe learn about the length of notes. I find it kind of hypnotizing looking at the piano playing, or listening to fancy rhythms.
Java programmers can here find a few useful examples on how to use MIDI in Java - I did not find much (understandable) about it on the web when I wrote this GUI in 2009.
Many thanks to Wei in Tuebingen (Snowmans Dream) who showed me as a musical analphabet to play the piano in just two days back in 2009 - without his teaching I would never have never written this -, many thanks to the project creators of the Gervill project - without their work I would have stopped in the beginning because the default Java Soundbanks sound is so poor, and of course many thanks to those who put their MIDI files online for everybody; I have packed some of them into the current distribution.
