[PD] Fun with additive synthesis

[David Powers]

Hi,

Great, I found it, and I'll play around with it to see what I come up with.

If I have time, I might see if I can use PD to parse some of the data
automatically. However, there's far more data than would be practical to
use, so, I probably need to write some kind of Python script first to create
a simpler file format where only the first 32 harmonics are included, and
each file states which note it is for and any other needed information
(which is currently found only in the CONTENTS for each folder).

Also I need to convert the volumes in dB to something between 0 and 1.
