additional parameters:


Here the spectrum is varied, in proportion to the amplitude of
the tone, a situation commonly encountered in  "natural" music
instruments. The technique is frequently used by musicians and
referred to as harmonic enveloping.

Care has to be taken to choose the correct scaling factor
mediating between amplitudes and bandwidths. In this case the
bandwidth is 10% of the amplitude value of the tones. Some
different amplitudes values are presented in the score, ranging
from 4000 to 160000.

Note also: If RESON is used as a low pass filter (icfq=0), the
actual cutoff frequency of the filter will be .707 times the
value of kbw. (Dodge 1985: p. 174)
