Freq:
The Frequency parameter determines the filter cutoff frequency or the
frequency the filter uses as the highest frequency allowed to pass.
If you play the keyboard now, you should hear the raw sound. Slowly
decrease the filter cutoff frequency value as you play the keyboard. The
sound gets more and more dull as you remove more and more high
frequencies from the sound. At some point, the sound completely disap-
pears. (You have filtered out everything.) The chart on the following page
illustrates what you just did.

Open the filter back up to 255, then move the cursor to the Q field.

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).
Reset the cutoff frequency to the lowest setting and the Q to 00.
