[PD] distortion

[David N G McCallum]

	Speaking of waveshaping, does anyone know how I'd go about getting
a waveshaping equation into a table for tabread4~?

	For example, say I want to use the equation:

f(x,a) = x*(abs(x) + a)/(x^2 + (a-1)*abs(x) + 1)

that I got off musicdsp.org. Where a is a variable and x is the input
sample value.

	I can think of running a line through the equation and into the
table, but that seems like an awfully stupid way of going about it.
