CREATING SOUNDS
VALUE
TIMBRE
This determines the cutoff frequency of the low-pass
filter. The higher the cutoff frequency, the less effect the
filters have on the basic waveforms (since more fre-
quencies are passed).
At the highest value, 63, all harmonics are passed. The
lower the value, the more harmonics are cutoff, so the
sound becomes progressively rounder or less bright.
This emphasizes the harmonics near the cutoff frequen-
cy, producing a characteristic peaky or
bandpass
type
of sound.
The higher the value, the higher the resonance peak
and the more obvious the effect. At or near the maxi-
mum value 31, the
VCFs
go into self-oscillation, produc-
ing
a pure sine wave, which can be used as an addition-
al sound source for special effects. The pitch of the
VW
tone is affected by the Cut Off, Keyboard Track, EG INT,
and MG VCF parameters.
