[music-dsp] Line6 nonlinear function

[tbpetrus at netscape.net]

Hi group,

Please forgive me if this has already been posed.  Referring to the
non-linear function corresponding to Figure 14 in the Line6 patent, it
seems there is a missing parenthesis for the x < -0.08905 condition.  I
tried in matlab to add a matching paren at various places in the
function but had no luck duplicating the plot. Also, other references to
the function are not fully printed (except for "-3/4") in the .pdf file
of the patent.  The equation as in Fig 14 is:

f(x) = -(3/4 (1-(1-(|x|-0.032847)^12 + 1/3(|x|-0.032847)) + .01),
    for x < -0.08905

Thanks,
brad
