I’m taking my first steps into the world of JavaSound programming. The first thing I learned is that the Snow Leopard default
javax.sound.midi.spi

byte[] msg = new byte[n];
for (int i = 0; i < n; i++) {
msg[i] = (byte) Integer.parseInt(
s.substring(i * 2, i * 2 + 2), 16);
}
The next step is to send the resulting byte array to a MIDI out...
