additional parameters: ipeakbw, iratebw


The instrument gives continuous control over the bandwidth of a
noise with a simple, but ingenious use of an LFO oscillator. A
sinus is taken from its lowest point at 270 degrees. By addition
of 1 and dividing by 2, the sinus takes on an all positive and
normalized bell shape. Applying the peak bandwidth value
completes the bandwidth controlling contour. The contour will run
at irate times a note, as irate is duration dependent.
The four notes played by this instrument show four different
settings that lead to very different tone qualities. Sounds can
be described as "rustling", "thumping", "scurrying",
"ringing","blowing", etc. (Dodge 1985: p. 171)
