Amplier Envelope
Sequential
As noted previously, the Amplier Envelope often works in conjunc-
tion with the Filter Envelope, with the Filter Envelope controlling
how the lter opens and closes and the Amplier Envelope control-
ling how the Amplier controls the overall volume shape of the
sounds you create.
To hear the effect of the Amplier 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. Repeatedly strike a note on the keyboard as you turn the Amplier
Envelope’s attack knob clockwise. Notice how the attack becomes
slower and more gradual the further you turn the knob.
3. Reset the attack parameter to zero.
4. Next, repeatedly strike a note on the keyboard as you turn the Ampli-
er Envelope’s sustain to zero. Notice how it changes the sound so that
the sound no longer sustains even if you hold down the key. The only
sound you hear is the decay portion of the sound.
5. Now, with sustain still set to zero, repeatedly strike a note on the
keyboard as you turn the Amplier Envelope’s decay knob clockwise
and counterclockwise. Notice how it changes the sound as the note
decays faster or slower after its initial attack stage.
6. Reset the decay parameter to 127
7. Finally, with decay set to 127 and sustain still set to zero, repeatedly
strike a note on the keyboard as you turn the Amplier Envelope’s
release knob clockwise. Notice how the release becomes longer the
further you turn the knob.
8. Continue experimenting with various Amplier Envelope settings while
you also adjust the Filter Envelope to hear how these two controls
interact. You will understand how powerful the envelopes are and how
essential they are to designing sounds.
