Filter
The function of the filter is to subtract frequencies from the sound
produced by the oscillators and noise generator, thereby changing the
overall harmonic content of the synth’s sound. This change is varied over
time using the Filter Envelope to produce more dynamic timbres.
The Filter section
To hear the effect of the filter:
1. Recall the Basic Program by pressing the
global
button and using the
select
knob to navigate to the
basic program
command, then press
write
.
2. Hold down a note and rotate the filter’s
cutoff
knob. Notice how it cuts
the high frequencies as you rotate counter-clockwise, making the sound
of the oscillator less bright. If you turn the
cutoff
knob fully counter-
clockwise you’ll filter out all frequencies and hear nothing.
3. Return the
cutoff
knob to its halfway position, hold down a note again
then turn the
resonance
knob about halfway up.
4. Rotate the filter’s
cutoff
knob again and listen to the sound change as a
band of frequencies near the cutoff is amplified. This is how to create a
classic resonant filter sweep.
In the previous example, you controlled the filter cutoff by hand. In most
cases, you will use the Filter Envelope to do this. To learn more about the
Filter Envelope, see “About the Filter Envelope” on page 24.
