Secondarily, the keyboard's pitch is also used to modulate other sources, such as filter
cutoff.
If you do not use a MIDI keyboard, you can also play on the virtual keyboard of the Jupiter-8V, but your
MIDI sequencer will not record those actions, it is for auditioning presets and programming only.
8.2.2
The envelope generator or ADSR
If we stop here, the sound that you will obtain will be uniform, without life and without
an end!! The oscillator delivers a sound signal (the audio output of a waveform) of a
fixed pitch in a continuous manner. In the diagram above, the only way to control this
sound is to lower the filter cut-off frequency so that it becomes more and more damp
until it finally disappears; or simpler yet, lower the volume of the amplifier.
The envelope generator, connected to the VCA, is used to «sculpt» the volume of the
sound when we press a key on the keyboard and ends after the note is released.
The most common modules developed use 4 settings that we can vary:
•
The
A
ttack is the time that the sound will take to reach its maximum volume once
we have pressed a key on the keyboard.
•
The
D
ecay is the time that the sound will take to diminish after the attack portion
is complete.
•
The
S
ustain is the maximum volume level that the sound will reach after the
decay is complete.
•
The
R
elease is the time that the sound will take to diminish once the key has been
released.
