I am talking basicaly to myself here anyway

I get no sounds from the program. It's boring looking the window it opens and having no output.

A comment on the last code shown
new byte[]{(byte)240, (byte)67, (byte)117, (byte)(sys_k-1),
(byte)(24+kan-1), (byte)(64+par), (byte)(dat_l), (byte)(dat_h), (byte)247});
Does the byte array have to be created each time or can it be created one time and used more than once? Make it a class variable with final attribute

To hear sound you need a midi-axclusive machine like yamaha FB-01
I understand it is borrow
I need to talk to some one who has that machine and a PC
by the way changed to loop on make into

if(mmjflag) {
try {
Thread.sleep(4); // delay loop of 4 mil sec for midi send
}
catch (InterruptedException e) {
}
}

which works and is much better.
I´ll look into your last remark
