Adjusting the Level Parameter
The Level parameter specifies the amplitude of the envelope at the position set by the
Time parameter. The Amp and Filter envelopes are unipolar. Therefore, the value
range for the level is 0 % to +100 % (positive values only). The Pitch and User
envelopes are bipolar, the value range for the level is from -100 % to +100 %
(negative and positive values) for these envelopes.
You can change the polarity of the envelopes in the modulation matrix, for instance, to
map the range of the Amplifier Envelope (unipolar) to Pan (bipolar). However, the
envelopes always display their values with their default polarity.
• To set the Level parameter, select the nodes you want to edit and enter a value in
the Level field.
You can also adjust the Level parameter in the graphical envelope editor by dragging
the selected nodes up or down, to decrease or increase the levels.
• For a higher resolution, hold [Shift] while moving the nodes.
• Hold down [Alt]/[Option] while dragging to limit the movement to the level axis
(vertical positioning only).
Adjusting the Curve Parameter
The Curve parameter allows you to adjust the curvature between two nodes from
linear to logarithmic or exponential behavior.
To set the Curve parameter, select the nodes you want to edit and enter a value in the
Curve field. Positive curve values change the curvature towards logarithmic and
negative values towards exponential behavior.
You can also adjust the Curve parameter in the graphical envelope editor by dragging
the curvature of an envelope segment.
• [Ctrl]/[Command]-click a curvature to reset it to linear.
Adding and Removing Nodes
The envelopes Amp, Filter, Pitch, and User can have up to 128 nodes. All nodes
added after the sustain node always affect the release stage of the envelope.
• To add a node, double-click at the position where you want to add the node.
• To remove a node, double-click it.
• To delete several selected notes, press [Delete] or [Backspace].
You cannot remove the first, the last, or the sustain node.
Adding Nodes Using the Fill Function
The Fill function allows you to add multiple envelope nodes after the selected nodes:
1. On the pop-up menu to the right of the Fill button, select the number of nodes you
want to add.
2. In the graphical envelope editor, select the node after which you want to add nodes.
If several nodes are selected, the new nodes are inserted after all selected nodes.
3. If the Fixed function is deactivated, the added nodes are placed with the interval
specified by the Time parameter of the selected node. If multiple nodes are
selected, the interval is specified by the focused node.
By activating Sync, you can specify the interval with the Sync note value. For
example, if 1/4 is selected, new nodes are added at exact quarter note intervals.
4. If the Fixed function is activated, the added nodes fill the space between the last
selected node and the following one.
5. Click the Fill button.
The nodes are added.
