Envelope (Env)

The first screen of the parameter menu for the envelope is seen below:

The envelope controls the variation of the oscillator volume over time. A string sound fades in
with a slow attack but a piano or a guitar string has a fast attack time. In this manner we can
control the characteristics of our sound. This can be described by the figure below:


The parameters are:

A (Attack):

The time the envelope takes to reach full level.

D (Decay):

The time it will take to reach the sustain level.

S (Sustain):

The volume level to keep when a key is held.

R (Release): The time it takes for the sound to fade out after the key is released.

All parameter values are defined from 0 to 15.

Moving the focus to the extreme right accesses the second screen:

The Gate-switch, when active, replaces the SID chip hardware envelope found on screen 1 with
a software gate with amplitude of the Sustain. Since the SID envelope now is not used this gives
