Hi,

I'm doing a music reader with matlab. I'd like to add a progress bar for the music, a slider I think. But I have a problem : How can I update the slider in real time during the play back of the music ?

Thank you

Thank you but I'd like to use a slider because I want to have the possibility to choose the part of the music I want to play.

I do not have the time just at this moment to try it out but this link http://www.mathworks.com/matlabcentral/answers/95933 does seem applicable. Looks like you can use the player.TimerFcn to call a function that increments the slider as it plays. Will need to play and read up a bit to figure out how to get the slider update if it is manually moved and skip to the correct audio time .
