I uploaded a file called chebyshev.256 These waves smoothly morph within a bank
but should be driven by a sine wave (not a saw tooth wave) for the best results.
I think the last wave-set (bank) comes from the polynomials that produce a trumpet
sound (I'll have to look it up). Each bank morphs from the input sine wave to the
last wave (which is the one produced via the polynomials) in the bank. Have fun.
