SYNOPSIS

    use Audio::LADSPA::Network;
    use Audio::LADSPA::Plugin::Play;
    use Audio::LADSPA::Plugin::Sequencer4;

    my $net = Audio::LADSPA::Network->new( buffer_size => 100 );
    my $seq = $net->add_plugin( 'Audio::LADSPA::Plugin::Sequencer4' );
    my $sine = $net->add_plugin( id => 1047);
    my $delay = $net->add_plugin( id => 1043);
    my $play = $net->add_plugin( 'Audio::LADSPA::Plugin::Play' );

    $net->connect($seq,'Frequency',$sine, 'Frequency (Hz)');
    $net->connect($sine,'Output', $delay, 'Input');
    $net->connect($delay,'Output', $play, 'Input');

    $sine->set(Amplitude => 1);

    $delay->set('Delay (Seconds)' => 0.5);
    $delay->set('Dry/Wet Balance' => 0.3);

    $seq->set('Step 1',70); # midi note numbers
    $seq->set('Step 2',82);
    $seq->set('Step 3',96);
    $seq->set('Step 4',108);
    $seq->set('Run/Step',150);

    while (1) {
        $net->run(100);
    }
