Examples with VoiceStatus javax.sound.midi.VoiceStatus used on opensource projects

Example 1 with VoiceStatus

use of javax.sound.midi.VoiceStatus in project jdk8u_jdk by JetBrains.

the class NoteOverFlowTest method main.

public static void main(String[] args) throws Exception {
    AudioSynthesizer synth = new SoftSynthesizer();
    AudioFormat format = new AudioFormat(44100, 16, 2, true, false);
    AudioInputStream stream = synth.openStream(format, null);
    // Make all voices busy, e.g.
    // send midi on and midi off on all available voices
    MidiChannel ch1 = synth.getChannels()[0];
    // Use contionus instrument like string ensemble
    ch1.programChange(48);
    for (int i = 0; i < synth.getMaxPolyphony(); i++) {
        ch1.noteOn(64, 64);
        ch1.noteOff(64);
    }
    // Now send single midi on, and midi off message
    ch1.noteOn(64, 64);
    ch1.noteOff(64);
    // Read 10 sec from stream, by this time all voices should be inactvie
    stream.skip(format.getFrameSize() * ((int) (format.getFrameRate() * 20)));
    // If no voice are active, then this test will pass
    VoiceStatus[] v = synth.getVoiceStatus();
    for (int i = 0; i < v.length; i++) {
        if (v[i].active) {
            throw new RuntimeException("Not all voices are inactive!");
        }
    }
    // Close the synthesizer after use
    synth.close();
}
