Open the �lter back up to 255, then move the cursor to the Q �eld. 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 ampli�es the frequencies at the cutoff frequency (Fc). 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 �lter frequency during the course of the note. Before we de�ne the Filter Envelope, we need to patch the Filter Envelope to the Filter Frequency.

To Setup the Filter Envelope
