If you set sustain to 0, the sound will become silent after the decay phase is finished. With short attacks
moderate decay times, this can be used to simulate the behaviour of a plucked string instrument (gui-
tar, piano etc.) where the sound always decays to silence after a while.
If you release a key before the envelope has reach its sustain level, it will immediately jump to the
release stage. The effect of this is shown in the illustration below.
Often, envelope levels can be made to vary with how hard you play the keys. This is used to make a
sound vary with your playing style, for example to make the sound brighter (filter envelope) or louder
(amplifier envelope). On the Nord Modular Envelope modules that feature this function, there is an
Amp input.

A simpler type of envelope has attack and decay parameters only, and is therefore called an AD-envelope.
In effect, the AD-envelope behaves like an ADSR-envelope with sustain level set to 0. This type of enve-
lope, often with amount and inversion controls, is suitable when you want to affect the start of the sound
only. For example, it can be made to modulate the FM amplitude or the pitch of oscillators, to create a
different timbre during the attack part of the sound.
LFO
LFOLFO
LFO
An LFO is an oscillator, just like the ones that produce the sound in a synthesizer, but with two main
differences:
1. The LFO produces relatively low frequencies, most often below the hearing range (up to 20Hz).
