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
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.
