To hear the effect of the Filter Envelope:
1. Press the
global
button and use Soft Knob 1 to navigate to the
basic
program
command, then press Soft Button 1 (
write now
).
2. Press the
low
-
pass
1
button to select this filter type.
3. Hold down a note and rotate the filter’s
cutoff
knob to set it to
a value of 40 (refer to the main display to see its numeric value).
4. Play a note. At this point you may not hear anything because you’ve
closed the filter significantly.
5. In the Envelopes section, turn the Filter Envelope’s
amount
knob to a
value of 50 (refer to the main display to see its numeric value).
6. Play a note. Notice how the sound has changed. The Filter Envelope is
controlling filter cutoff by the amount you set with the
amount
knob.
7. Repeatedly strike a note on the keyboard as you turn the Filter Enve-
lope’s
decay
knob clockwise and counterclockwise. Notice how it
changes the sound as the note decays faster or slower after its initial
attack stage.
8. Now experiment with the Filter Envelope’s
attack
knob. Notice how
the attack becomes faster or slower.
9. Now hold down a note and experiment with the Filter Envelope’s
sustain
knob. This controls how wide the filter stays open while you
hold down a key on the keyboard.
10. The Filter Envelope’s
release
parameter acts in conjunction with the
Amplifier Envelope, so to hear its effect, first set the Amp Envelope’s
release
value to 75.
11. Now repeatedly strike a note on the keyboard as you turn the Filter
Envelope’s
release
knob clockwise and counterclockwise. Notice how
the note fades out faster or slower as you change the
release
value.
12. Continue experimenting with various Filter Envelope settings while
you adjust the Filter Envelope’s
env amount
knob. Notice how greater
amount
settings amplify the effect of the envelope on the filter.
As noted above, the Filter Envelope and Amplifier Envelope often work
in conjunction, with the Filter Envelope controlling how the filter opens
and closes and the Amplifier Envelope controlling how the Amplifier
controls the overall volume shape of the sounds you create. To learn
more about the Amplifier Envelope, see page 35.
