3. VCF
The Voltage-Controlled Filter (VCF) submodule contains three pages.
Page one determines the filter' s initial cutoff frequency and Q (reso-
nance). Page two determines the effect of keyboard position on cutoff
frequency, and the extent to which the associated AHDSR envelope
affects the filter cutoff frequency (envelope amount). Page three sets the
VCF AHDSR envelope characteristics. These alter timbre with respect to
time.
1. Activate Dynamic Processing module.
2. Select Submodule 3.
3. Move the cursor to the parameter(s) to be adjusted, and select
the desired value(s) with the data entry knob. The first page
reveals:
Cutoff:
Q:
• VCF Cutoff: varies the lowpass filter cutoff from 0 Hz to 22049Hz.
Higher values correspond to higher filter cutoff frequencies, hence a
sound with more treble. The maximum filter sweep range is most
obvious with envelope amount set to +0.
• Q: varies the resonance from 0 to 100%. Higher values correspond
to increased resonance, which accentuates the frequency response at
the filter cutoff frequency. This produces a sharper, more whistling
sound.
4. Select page two by pressing the right cursor button. The second
page shows:
Tracking:
Envelope Amt:
• Tracking: varies the filter cutoff with respect to the note(s) being
played on the keyboard from -2.00 to +2.00. With 0.00 tracking, the
filter cutoff will not be affected by the keyboard pitch. With tracking
set to -2.00, the filter cutoff will increase at one-quarter the rate at
which pitch increases. With tracking set to +2.00, the filter cutoff
will increase at twice the rate at which pitch increases. Intermediate
values give intermediate degrees of tracking. With negative tracking,
a sample will become progressively less bright as you play higher up
in the zone. This is useful with some bass sounds, and to even out
frequency response variations between samples when multi-
sampling.
