Audio Damage Basic - Manual (Page 10)

The LFO works slightly different. It is bi-polar, meaning that it can also subtract value from the Frequency control. So you’ll get the
best results when the Frequency is set towards the middle of its range. Once you learn the interaction, this will become more
obvious. We suggest experimentation is the best teacher in this regard. !

Envelopes: ! !
The two envelopes in Basic are of the attack/decay/sustain/release
variety, or “ADSR,” as they are known. The names of the knobs are
essentially what they do. Both envelopes trigger when Basic receives a
MIDI note on (with a caveat that we’ll discuss in a moment), and travel
through the first three stages (Attack, Decay, and Sustain) while the
note is held down. When the note is released, the Release stage
starts. !

The Filter Envelope can be applied to each filter individually with the
“ENV” sliders; this is generally used to give a particular bit of the sound
a certain emphasis. For instance, on a bass sound, you might want the
initial portion of the note to hit a bit harder, to replicate the sound of a
bass guitar being played with a pick. For this, you’d use zero Attack
and Sustain, a very short Decay, and a very short Release.
The Amp Envelope controls the final amplifier of the synthesizer, and
as such, it has a couple extra controls. It operates, on the whole, in the
same way as the Filter envelope, though. If you want a sound with a
soft, smooth beginning and a long release (to replicate, say, a violin
being played in a mournful fashion) you would have a long Decay, a high Sustain, and very long Attack and Release stages. !
Velocity & Retrig: !
The VELOCITY slider below the Amp Envelope controls the amount of note velocity applied as a multiplier of the envelope. If the
Velocity is at zero, every note will play at the same volume, the theoretical maximum as described by the envelope settings. If the
Velocity slider is all the way to the right, at full, the velocity can be considered as a 0-to-1 multiplier on the envelope. So if you play a
note at MIDI velocity 64 (which is halfway) the multiplier on the envelope’s values will be 0.5x, and the note will play half as loud as
