 Zoom to Fit button: Switch on to display the entire impulse response waveform. The
display will automatically follow any envelope length changes.
 A and D buttons: Click to limit the Zoom to Fit function to the attack and decay
portions of the (currently selected) envelope. The A and D buttons are available only
to the volume and filter envelopes.
Setting Envelope Parameters
Space Designer allows you to edit the volume and filter envelopes of all IRs, and the
density envelope of synthesized IRs. All three envelopes can be adjusted both
graphically and numerically (in the parameter bar).
While some parameters are envelope-specific, all envelopes consist of the Attack Time
and Decay Time parameters: The combined total of the Attack Time and Decay Time
parameters is equal to the total length of the (synthesized or sampled) impulse
response (determined by the Length parameter, see “Setting the Length of the Impulse
Response” on page 174), unless the Decay time is reduced.
 You can change the curve shape by dragging the envelope curve directly. Use the
small nodes attached to a line for finer adjustments to envelope curves. They are tied
to the envelope curve itself, so you can view them as envelope handles. Moving the
nodes vertically or horizontally will change the shape of the envelope curve.
 The large nodes are value indicators of the parameters that appear in the horizontal
parameter bar below—Init Level, Attack Time, Decay Time, and so on. If you edit any
numerical value, the corresponding node will move in the main display. Try this with
each numerical parameter to establish which node is which. When you move the
mouse pointer over one of these nodes, you’ll see a pair of arrows. The arrows simply
indicate the possible directions that the node can be moved.
