126 Chapter 10 Convolution Reverb: Space Designer
Envelope Window Node Handling
Before we get to the buttons, we’d like to briefly touch on the Envelope window of the
Space Designer GUI.
When first launched, a default synthesized Impulse Response and set of Envelopes are
automatically created.
You will see a few nodes placed around and within the Volume Envelope that is
displayed. These nodes are indicators of several parameter positions/values.
If you look carefully, you will see that some nodes are actually a little larger than others,
that some are filled and others are hollow. To explain:
• The filled parameters are active/selected. Hollow ones are not selected/active.
• The small nodes attached to a line are used for finer adjustments to Envelope curves.
We refer to these as the Curve Form nodes. More information on their use can be
found in the “The Volume Attack and Decay Curve Form Nodes” section, on page 130.
• The large nodes are value indicators of the parameters that appear in the horizontal
box below—Init Level, Attack Time, Decay Time, and so on.
If you click-hold on any numerical value, say the Init Level, and drag your mouse up/
down, the corresponding node will move in the Envelope window. Try this with each
numerical parameter to establish which node is which.
Now, move your mouse cursor over the edge of the node that controls the Init Level,
and you’ll see a pair of arrows. If you move your mouse cursor into the center of the
node, the arrows (and node) are filled. The arrows simply indicate the possible
directions that the node can be moved.
Experiment with each node/parameter in each of the Envelope window modes (see
just below) to get a hang of this. You’ll find that it’s very intuitive to use.
Reset
Here you can reset the currently selected envelope—Volume, Filter or Density—to
default values.
All
Here you can resets all envelopes to default values.
