Attack
An envelope always rises from 0 to 100% and
back to 0% when the key is released.
Attack controls how fast it rises to 100%. So if you open the Attack control knob, it takes longer to go from 0
to 100%.
With Attack closed, the envelope starts at 100%.
Decay
After the attack stage, with the envelope
at 100%, the decay stage is reached.
Decay reduces the envelope level to the
sustain
level over a set time. So if you use a long decay, it takes
longer to reach the sustain level.
If the sustain level is 100% the Decay has nothing to fall to and so the s
ustain stage is reached immediately
after the attack.
Sustain
Next we have the sustain stage. After the attack & decay stage, the envelope reaches the sustain stage and
remains here for as long as you have a key pressed down. The sustain level is the leve
l of this sustain stage.
Sustain level in the Free Envelope means that the "level"(amount) selected in the destination parameter
stays for as long as you hold down the key(s).
Sustain fade
If the fade is set to off, the sustain remains at the sustain leve
l i.e. it is a classic sustain
If you open the fade amount in a positive direction the sustain changes into a second attack.
So after the Decay reaches the Sustain level it starts rising to 100% again and the time it takes to reach
100% is set by the Fade
time.
If you open the fade amount in a negative direction the sustain changes into a second decay.
So after the Decay reaches the Sustain level it starts falling to 0% again and the time it takes to reach 0% is
set by the Fade time.
Release
After you have
released a key (note) the release stage starts. The envelope then decays from the sustain
level to 0%, the amount of time this takes is set by the release knob.
VEL > time
This controls how the envelope responds to the velocity of notes pressed.
If you
use a positive amount, the envelope times get shorter for higher velocities.
If you use a negative amount, the envelope times get longer for higher velocities.
KT > time
This controls how the envelope responds to the notes pressed.
If you use a positive a
mount, the envelope times get shorter for higher notes.
If you use a negative amount, the envelope times get longer for higher notes
Destination Envelope 1
This is where you can select the destination the Envelope 1 modulation.
Listen to preset "Pred Bras
s" in the first bank. In this preset the
fine pitch
of Oscillator1 is modulated by
Envelope 1.
