I am programming an application, that uses javax.sound.midi, prepares a sequence and sends it to a synthesizer. Now I would like to play the "melody" with sounds, that I assign myself.
So I thought I would find an open-source software synthesizer where I could assign various wave files to midi instruments and then access the synthesizer software from my java program. The java program is supposed to connect its transmitter to the receiver of the synthesizer and play the melody.
However I did not find a suitable software. Could somebody hint me to such a synthesizer? Or maybe tell me, what I am actually looking for. I searched "midi software synthesizer", "midi soundbank from wave files" and the like.
It should preferably be platform independent or run on linux and os x.
