The Amplitude Envelope (AMPENV) Page
7-49
If you want to build your own amplitude envelope, just turn the Alpha Wheel a click. e
value Natural will change to User, and a set of AMPENV parameters will appear. e sound
will change when you do this, because the settings for the User envelope take eect as soon as
you leave Natural mode. Returning to Natural mode applies the original amplitude envelope
once again.
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 parameter 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.
