Hi Everyone!

I am new to Java and learning through HeadFirst.

MidiSystem.getSequencer() is throwing exception.

Even my system is having four MidiDevices(software implemented).


The exception is:
javax.sound.midi.MidiUnavailableException: MIDI OUT transmitter not available

How to solve the issue?

Please help!

Thanks and Regards,
Charanjeet singh

This problem is solved.

But now the program is not making any sound?

import javax.sound.midi.*;

public class MiniMusicApp{
public static void main(String[] args){
MiniMusicApp mini = new MiniMusicApp();
mini.play();
}

public void play(){
try{

MidiDevice.Info[] deviceInfo = MidiSystem.getMidiDeviceInfo();

System.out.println(deviceInfo.length);

MidiDevice md = null;


for(int i = 0;i < deviceInfo.length;i++){
if(deviceInfo[i].getName().contains("Sequencer"))
md = MidiSystem.getMidiDevice(deviceInfo[i]);
System.out.println(deviceInfo[i].getName() + " : " + deviceInfo[i].getVendor());
}


Sequencer player = (Sequencer)md;
player.open();

Sequence seq = new Sequence(Sequence.PPQ,4);

Track track = seq.createTrack();


ShortMessage a = new ShortMessage();
a.setMessage(144,1,44,100);
MidiEvent noteOn = new MidiEvent(a,1);
track.add(noteOn);



ShortMessage b = new ShortMessage();
b.setMessage(128,1,44,100);
MidiEvent noteOff = new MidiEvent(b,1);
track.add(noteOff);

player.setSequence(seq);

player.start();
}
catch(Exception e){
e.printStackTrace();
}
}
}


Please Help...

Welcome to JavaRanch Charanjeet. I would suggest you study the "OCJP for java 6" book by Kathy Sierra and Bert Bates if you are new to the language. It is written in lay man language and easy to understand. You need to get the fundamentals crystal clear.
