Enabling and Disabling Automation Quick Access
If you choose the modulation wheel for Automation Quick Access, you might want to
switch between using it for Automation Quick Access and normal modulation wheel
duties—as MIDI controller 1.
This is most efficiently done with the Toggle Automation Quick Access key command
(default assignment: Control-Option-Command-A).
Using Hyper Draw in the Arrange Area
Hyper Draw works much like track automation, with a couple of key differences:
• Hyper Draw data is restricted to MIDI regions.
• Hyper Draw data uses MIDI controller values (rather than the internal meta events used
by the track automation system), which are represented as lines between nodes.
You can edit nodes and lines in a similar way to track automation data.
You can record MIDI controller events in real time on MIDI tracks, or use Hyper Draw to
create and edit controller events in the Arrange area, Piano Roll, and Score Editor. The
Hyper Editor is purpose-built for MIDI controller editing, providing more precision and
flexibility than the Hyper Draw options of other windows.
Numerical MIDI controller values are automatically displayed as Hyper Draw nodes. These
values are context-sensitive—the centered pan position is displayed as 0 (not 64), and
volume is displayed in dB, for example. If no events exist, Logic Pro automatically creates
a horizontal line (of the current value, if available).
You can use any of the 127 MIDI controller values to automate parameters such as volume
or pitch, for example.
