ENVELOPE TO VCA
The BASIC PATCH has the VCA (Voltage Control Amplifier) set to GATE, which means
that the sound will come on when you press a key and will shut off when you release it.
To control the LEVEL of audio using the ENVELOPE, move the VCA switch to the ENV
position. Figure 11
Figure 11
Since the SUSTAIN slider is at the maximum setting and the ATTACK, DECAY and RELEASE
settings are at the minimum settings, you will hear the same thing that you would hear
with the VCA set to GATE. Now let’s shape the sound’s amplification envelope, which
determines how the level changes over time when you play a note. Until now the
Sustain level has been set to maximum, which results in an “electronic organ” sound
that has no dynamics.
By changing the ATTACK, DECAY and RELEASE parameters we can control how the
sound fades in, sustains, and fades out. Set the SUSTAIN to the minimum setting, play
with the ATTACK, DECAY and RELEASE settings, and listen to how they affect the sound.
