trigger random sound files

I’m a bit of a newbie to max/msp/jitter
I’m just wondering if anyone can help me. I want to randomly trigger different sound files to play when a bang triggers.
I have been fiddling around with sfplay, preloading in files as messages etc..But i’m not sure if i’m going about it the correct way!!

Any suggestions appreciated! Smile

there are several ways, your way ok, have a look at the sflist obj, it might be useful. trigger the cuepoints with the random obj.

the object umenu might help you too. you can get the filenames of a folder of files into the menu and trigger them with the random obj

a more flexible way is to use in case you work with jitter since it reads everything quicktime reads inluding mp3 and the like. There is an example called Poly~ForMovies which is very cool….

Hi Falk,

Thanks for the reply,
I’m not sure if i’m doing this right, it does not seem to be working for me at the moment. I tried the sflist object with the random object, don’t think i’m doing it right..
I’ll paste it here. What i’m actually trying to do is create a set of triggers that will play random sounds as the frames change in the movie! I am using jit.change which is working, it outputs 0 if frame changes, and 1 if it does not. The problem i am having now is triggering off the different sounds…I don’t think that this is very hard to do, although i can’t seem to do it…
