An envelope is used to give a sound a "shape". If you apply an envelope to the amplifier (which controls
the volume) you are able to make the sound for example slowly fade in and then fade out when you press
and hold a key.

LFO is an abbreviation for Low Frequency Oscillator. It is used for repeating variations in a sound, such
as vibrato or tremolo.

There are many ways in which the modules outlined below can be connected in a synthesizer, but the one
in the picture below is a basic and common one, used in the Nord Lead 2X (although the illustration
depicts far from all the possibilities in this instrument!)
Note that the horizontal lines indicate the way the sound travels. The vertical lines indicate control sig-
nals. The envelopes for example only modulate (control) the oscillator, filter and amplifiers, they do not
affect the sound directly.

The two basic qualities of an oscillator is waveform and pitch.

The picture of the sawtooth on the Nord Lead 2X front panel displays a sawtooth during one period of
sound. During this time, the wave raises gradually up to maximum level and then instantly drops back
to minimum level.
