VS2010 C # Function Using Loop

Question

I am currently implementing my latest project as a student in software development for music. I am making software that plays a midi track that is generated earlier in the process.

There is a play button and a stop button in my interface. When I press "play", a loop is called that plays this track. In this loop, I call a function from an instance of another class.

What I would like is that when the user presses "pause", the cycle stops temporarily, and when he presses "pause" again, he returns to exactly where he was in the cycle.

While I press the play button, the track plays back what I want, but I cannot use any other element of my window until the loop is fully processed.

Here is my code.

private void playStopButton_Click(object sender, RoutedEventArgs e)
    {
        // Initialising my output midi devices
        outDevice.Send(new ChannelMessage(ChannelCommand.ProgramChange, information.bassChannel, information.bassSound));//bass
        outDevice.Send(new ChannelMessage(ChannelCommand.ProgramChange, information.guitarChannel, information.guitarSound));//guitar

        for (int barNum = 0; barNum < Globals.numberOfBars; barNum++)
        {
            // playing the first beat
            rythmicPattern.play(0, ref outDevice, information, Globals.chordProgression.Bars[barNum].Chord);

            //second beat
            rythmicPattern.play(1, ref outDevice, information, Globals.chordProgression.Bars[barNum].Chord);

            //thrid beat
            rythmicPattern.play(2, ref outDevice, information, Globals.chordProgression.Bars[barNum].Chord);

            //fourth beat
            rythmicPattern.play(3, ref outDevice, information, Globals.chordProgression.Bars[barNum].Chord);
        }
    }

private void playPauseButton_Click(object sender, RoutedEventArgs e)
        {
            // test if the track is being played
            if (isPlaying)
                rythmicPattern.Pause();
            else
                // if it was already paused, playing back from where I stopped
                rythmicPattern.PlayAfterPause(beatNumber);
        }

Thank you for your help. Greg

You should use streams where you can play sound in another stream so you can execute the pause method Check this link Multithreading in .NET: introduction and suggestions
