[PD] Controlling / looping a list of audio files loaded in by reading a text file.

[Rick T]

Thanks I went to http://puredata.info/downloads/zexy to pull out the
l2s.pd files to use and I couldn't find the pd files.  Do they go by
another name?

The reason for this is I only want to have the PD patches I'm really
using on the system.

Thanks
