3.
Turn the filter back up to full, then
adjust the Q
.
4.
Set the Q about halfway up, then adjust the
Cutoff
as you play the
keyboard. As you change the Cutoff, notice that the sound now has a
sharp, nasal quality. A high Q boosts or amplifies the frequencies at the
cutoff frequency (Fc).
Adding the Filter Envelope
Now let's modulate the Filter Frequency with the Filter Envelope. The Filter
Envelope is a device that can automatically change the filter frequency
during the course of the note. Before we define the Filter Envelope, we need
to patch the Filter Envelope to the Filter Frequency.
To Setup the Filter Envelope:
1.
Go to the
PatchCord
screen by pressing the
Cords
Jump Key.
2.
Move the
cursor
to
PatchCord #3
. This patchcord is preprogrammed to
connect the Filter Envelope to Filter Cutoff Frequency.
3.
Move the
cursor
to the last field in the lower line. This is the
Amount
field. The Amount field determines the amount of modulation applied.
Set this value to
+100
.
