Editing Presets
3.
Open the filter back up to 255, then move the cursor to the Q field.
4.
Set the Q to 10, then move the cursor back under the Freq value. As you
change the frequency, notice that the sound now has a sharp, nasal
quality. A high Q boosts or amplifies the frequencies at the cutoff
frequency (Fc).
5.
Reset the cutoff frequency to the lowest setting (0.08Hz) and the Q to
00.
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.
þ
To Setup the Filter Envelope
1.
Go to the PatchCord screen.
2.
Move the cursor below the first field in the bottom line of the display.
This is the Source field. Use the Data Entry Control to change the
Source to “FiltEnv” as shown in the following illustration.
3.
Advance the cursor to the next field. This is the Destination field. Use
the Data Entry Control to change the destination to “FiltFreq.”
