Man, is there anything Fourier Transforms can't do? For a music project in college, I created a book of Hammond Organ presets by taking slices of samples from actual instruments and running FTs on them, then finding the best approximation in Hammond drawbar notation. The fact that it worked so well was such a satisfying experience that I managed to make 100+ combinations.

I sort of did the reverse for a song once, I used FFT to analyze a recording of a drawbar organ I wanted to mimic, then turned that into a ZynAddSubFX additive synthesis preset.

This is where I started, actually! I wondered how far back I could go though, and the Hammond B3 worked extremely well.

Wow so you made an organ sound like a bunch of other instruments? You can't just post this and not share the sounds...

That is exceedingly cool. Is there anything available about this online? Sound clips, source code, etc.?

Most were typed up, but the source files were on a floppy disk somewhere in my closet. I can scan them in/upload them when I get a chance.
