38 Filter Envelope
Dave Smith Instruments
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 Key 1 (write now).
2. Hold down a note and rotate the lter’s cutoff knob to set it to
a value of 40 (refer to the main display to see its numeric value).
3. Play a note. At this point you probably won’t hear anything because
you’ve closed the lter signicantly.
4. In the Envelopes section, turn the Filter Envelope’s env amount knob
to a value of 50 (refer to the main display to see its numeric value).
5. Play a note. Notice how the sound has changed. The Filter Envelope
is controlling lter cutoff by the amount you set with the
env amount
knob.
6. 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.
7. Now experiment with the Filter Envelope’s attack knob. Notice how
the attack becomes faster or slower.
8. Now hold down a note and experiment with the Filter Envelope’s
sustain knob.
9. The Filter Envelope’s
release parameter acts in conjunction with the
Amplier Envelope, so to hear its effect, rst set the Amp Envelope’s
release value to 75.
10. 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.
11. Continue experimenting with various Filter Envelope settings while
you adjust the Filter Envelope’s
env amount knob. Notice how greater
env amount settings amplify the effect of the envelope on the lter.
As noted above, the Filter Envelope and Amplier Envelope often work
in conjunction, with the Filter Envelope controlling how the lter opens
and closes and the Amplier Envelope controlling how the Amplier
controls the overall volume shape of the sounds you create. To learn
more about the Amplier Envelope, see page 42.
