I stink at math. So I either import WAV's or go buy ear. Doe's any one have any
programming tips for those of us who are bad at math. I already have a good
understanding of additive synthisis it's just a matter of applying it without
having to drown in equations.

Anything that will reduce 64 choices to fewer choices will help. The higher
harmonics are not so important to real and analog sounds, so concentrate on
the first 16. Some ideas:
+Start with a full template like the saw and eliminate different sets of
harmonics. ("Additive Subtractive"?)
+Start with a thin template like the triangle and add different sets of harmonics.
+Pick individual harmonics. (Results in a lot of bells and drawbar organ sounds,
though. Some kinds of chimes use the series of squares:
1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121. Some use just the odd members of
that set.)
+Find harmonic spectra of real instruments (like the Sharc database) and copy
what you see by hand.
+Max all the harmonics, or a group of them, or use a template, and then use the
envelopes, FF, filter and effects to shape the sound. You can get a nice
"sting" by maxing some higher (>8) harmonics, sweeping the FF across, and
adding heavy distortion or overdrive.
Hope that helps.

You could use a spread sheet like Excel to do the math for you. Or if you have
a PC you could download PaCifiST and use my Wavemaker program (shameless plug)
which implements some of the formulas that have been posted here.
If you want to dig into the math, I would suggest reading Trigonometry The Easy
Way by Douglas Downing, Ph. D. Chapter nine even shows some formulas for adding
sine waves together just like additive synthesis.
Believe me, if I can learn this stuff, anyone can.
