4.11 The Filter Module
In order to expand the sonic possibilities of String Stu-
dio, a multi-mode filter has been inserted between the String
and Body modules. This multi-mode filter includes a res-
onant low-pass, band-pass, high-pass, notch and a formant
filter which can be selected using the Type drop-down menu.
The order of the filter can be adjusted to 2 (-12 dB/oct for
low-pass and high-pass and -6 db/oct for band-pass) or 4
(-24 dB/oct for low-pass and high-pass and -12 db/oct for
band-pass) with the help of the Order drop-down menu.
The resonance frequency of the filter is adjusted with the
Cutoff knob while its Q-factor or resonance is controlled
with the Q knob. When the formant filter is used, the Q knob is used to cycle between the vowels
(a, e, i, o, u).
