Controlling "sfplay~" with Javascript to play audio files

July 7, 2010 | 9:23 am

Hi everybody,

I’m pretty new to MaxMSP, and I’ve got some troubles to run sfplay~ with Javascript.

In order to play an audio file with sfplay~, you usually put a message button with delivers the message "open sound.wav", and then a toogle box sending "1" to play the file and "0" to stop the file.

So there’s my js code (I just want to play the sound.wav) :

function play_sound(){
outlet(0,"open sound.wav"); // This line isn’t understood by sfplay~
outlet(0,1); // This line is understood by sfplay~
}

If you put the js outlet into a "print", you’ve got the attempted result.
However, this error appears : "sfplay~ – no open file" which means that sfplay~ understand the second line but not the first (if you previously load the audio file with a msg box, the sound plays well).

How sfplay~ can understand my first line?

Thanks for your help (I hope i’m clear enough)

Ok, after some research I found the answer. It’s a common problem : spaces have to be replaced by commas in the outlet function.

So like this :

outlet(0,"open","sound.wav");

And it works !
