I am unable to download his files from the MIT resources page. They just come out garbled and not in the form of a pure data file. http://mitpress2.mit.edu/designingsound/birds.asp

A while ago I found another source of these folders but cannot seem to locate them.
Does anyone have any insight?

All help greatly appreciated.

@rayinoak I Found it. I had to look a little further.

@rayinoak To use the files on his site you will have to do the same as with Pd files uploaded to this forum.
Copy the contents (select all, copy) into a basic text window, save it and then change it's name to what_you_want.pd
In windows a .txt file will work.
In other os's I don't know, but any file that tries to format the text when it is saved (such as word .docx and probably Mac .rtf)) will corrupt the file.
