The Amplitude Envelope (AMPENV) Page
7-50
You’ll tweak the parameters on the AMPENV page when you want to shape the amplitude
characteristics of your sounds. A graphic view of the amplitude envelope will appear on the
display to give you a visual sense of the envelope’s characteristics. e dots along the envelope
graphic indicate the breakpoints between the envelope’s various segments.
e AMPENV page’s top line gives you the usual location reminder, points out the currently
selected layer, and tells you the relative scale of the envelope’s graphic view. e envelope
graphic shrinks in scale as the segment times get longer. is auto-zoom feature maximizes
the available display space. Try lengthening one of the segment times. e envelope graphic
will stretch to ll the display from left to right. When it lls the display, it will shrink to half
its size, and the top line will indicate that the scale has changed (from [1/1] to [1/2], for
example).
Each of the user envelope parameters on this page has two values, as listed below. For the
envelope segments, the rst (upper) value is the duration of the segment, and the second is
the amplitude level at the completion of the segment. For the Loop parameter, the values
dene how the envelope loops, and how many times the loop cycles.

Attack Segment Times
ese indicate how long it takes for the current layer’s amplitude to reach its nal level from
its starting level.
Attack Segment Levels
ese are the nal levels that each segment achieves at completion. e levels are expressed
as percentages of the maximum possible amplitude for the current layer. Attack segment 1
always starts at zero amplitude, and moves to its assigned level in the time specied by its
time value. So the default settings of 0 seconds and 100% mean that the rst segment of the
attack section moves instantly from zero amplitude to 100% amplitude. Increase the time of
Attack segment 1 if you want the sound to ramp up more slowly.
