320 Chapter 7 Automation
The display of the contents of the automation folder makes it easier to edit the
automation data independently from Regions. In normal circumstances, however, it’s
usually quite useful to see the Regions while designing the mix. As such, you’ll
probably find that you rarely open this folder view.
Automation Quick Access
This feature makes Track Automation extremely fast and simple if you only have one
hardware MIDI controller available (one fader on your MIDI keyboard, or maybe just the
Modulation wheel). You can use this single hardware controller to access (and
automate) the currently visible Automation parameter of the selected Track in the
Arrange window.
Setting Up Automation Quick Access
Open the Automation Settings dialog: Options > Track Automation > Track Automation
Settings.
There is a section called Automation Quick Access, which can be enabled or disabled via
On and Off radio buttons. Once enabled, a dialog will prompt you to move the desired
controller. Move the hardware controller that you’d like to use for Automation Quick
Access. Click the Done/Learn Message button below. The other parameters shown (via a
click on the Edit button) here will immediately identify and indicate the type of control
element you are using (even quite exotic formats are supported). Disable the Learn
Message button, by clicking on it a second time (the Done button), or close the
Automation Quick Access dialog.
Once set up, you will have hardware control over any currently visible Automation
parameter that is selected in the current Arrange track.
Enable/Disable Automation Quick Access
Should you choose the Modulation Wheel for Automation Quick Access (AQA), you
might want to switch between it’s use for AQA and “normal” Modulation Wheel
duties—as MIDI controller #1.
This is most efficiently done with the global Toggle Automation Quick Access key
command.
