I've been using max for a little while and feel pretty comfortable doing most things but I'm really confused when it comes to handling/loading files and folders. There just isn't much documentation on the subject.

So. What I'm trying to do is pretty simple. I want to be able to randomly play samples from a folder that contains a large pool of samples.

Sometimes it works, sometimes it doesn't.

Am I doing this right? I'm sure there are better ways to do this.

Also I can't seem to get it to "see" wav files. Only aiff.

Your patch worked reasonably well once I changed the 'types aiff' 

Mac OS Finder File Types (as used by the folder object) are 

case-sensitive. Even on Windows, most Max objects, for historical 

reasons, use Finder File Types. (Case-insensitive) MS-DOS file name 

extensions are mapped to Finder File Types in your init folder.

I would also be inclined to use sflist~/sfplay~ instead of buffer~s and 

to use lp.tata instead of random, but those are different matters.

Thanks for the speedy response. I've managed to work out the quirks and everything seems to be working good enough. I'm still not sure what to do about the random triggering. I want to use a bunch of these "modules" to create non repeating polyphonic "explosioins" pulled from the sample pool. So I need something like [urn] but it has to have multiple outputs that don't repeat. I'm not sure how I would do this in max. Is there an external/max object out there that could do this? I can't find anything in the reference manual. I'm sure this is a pretty common procedure. Any help?

Uzi->urn->spray will probably do what you want. You can build an 

abstraction to filter repetitions (there are some examples of this in

Well, I haven't copied and pasted yet, but after scrolling through that patch, all I can say is, wow.

Take look at the one of the patchers in the help file for sfplay~. 

There is very specific info there re: multichannel sound files.

short version - increase your sfplay~ buffer sizes.

search the archives for -
"sfplay~ dropouts ..."  or
"soundfile playback randomly quits"

yes i've seen this topics. but don't find the right buffer size to put.

and i don't know if i have to change only the buffer size of sfplay or if i have t change I/O vector size and signal vector size too.
