Chapter 16 Editing MIDI Events in the Piano Roll Editor 433
Using Hyper Draw
You can directly create and edit MIDI controller information in the Piano Roll Editor.
These types of edits are made easier when you can see the notes that will be affected.
To view and create controller events:
1 Open a Hyper Draw display in the Piano Roll Editor by doing one of the following:
 Choose the desired View > Hyper Draw command.
 Click the Hyper Draw button at the lower-left corner of the Piano Roll Editor, then
choose the desired MIDI controller by clicking the arrow button to the left.
The selected controller type (volume, for example) is shown in a gray field below the
Piano Roll grid.
2 Click at different points in the gray area to create Hyper Draw nodes.
A connecting line is automatically created between the nodes.
