The First Oscillator

 

To this point, we have turned our attention ex-
clusively to sound-shaping functions and have
always started with the same basic material: a
so-called sawtooth wave. This waveshape is
especially well-suited as a neutral starting point
as it contains all of the so-called natural scale of
overtones, which give the filter plenty of quality
material to work with.

The filters, with the exception of a notch filter or
band stop (BS), trim the far reaches of the tonal
spectrum, so for instance a signal sounds mud-
dier after it has been routed through a low pass
filter. You can well imagine that this type of
sound modification is substantial but insuffi-
cient for shaping more subtle differences in
tone. For instance the tone of a trumpet differs
significantly from that of a saxophone even
though no one would seriously claim that either
of the instruments has a muddier tone than the
other.
