ARTURIA – JUPITER-8V – USER’S MANUAL 70
The amplifier (VCA)
This module is very simple, it consists of:
VOLUME Knob to set the volume of the synthesizer
LFO MOD Slider to set the intensity level of the modulation by the LFO.
The amplifier’s volume is directly affected by envelope 2 (ADSR2).
7.1.5 The ADSR Envelopes
The «ADSR» envelopes allow several parameters to be controlled with the help of the
keyboard as a trigger. You will find two envelopes on the Jupiter-8: one unit for the
cutoff frequency of the filter (as well as the frequency of VCO2) and another one to
modulate the VCA amplitude.
When playing the keyboard, the envelopes will trigger and modify the way to sound will
be heard.
The ADSR envelope of the filter
The ADSR envelope consists of 4 different parameters:
ATTACK The Attack is the time that the sound will take to reach its maximum
volume once we have pressed a key on the keyboard.
DECAY The Decay is the time that the sound will take to diminish after the
attack portion is complete.
SUSTAIN The Sustain is the maximum volume level that the sound will reach
after the decay is complete.
RELEASE The Release is the time that the sound will take to diminish once the
key has been released.
KEYFLW Switch to connect envelope 1 and/or 2 to the keyboard follow. When
the switch is “ON”, the envelope times – “A”, “D” and “R” – will be as
shorter as you will play the higher notes on your MIDI keyboard.
