9.2 : Working With Rack Filters
The Rack Filter Editor
To display the rack lter editor, click the racks button at the top-right-hand corner of the edit page, or
press CTRL + G (CMD + G for Mac users). The arrange area will be reduced in size slightly and a rack
editor strip (Fig. 9.2.1) will be shown below it.
If you look at Figure 9.2.1 you will notice three pins on either side of the rack canvas. These pins
form the inputs (on the left-hand side), and the outputs (on the right-hand side) of the rack. The top-
most input and output pins carry MIDI data. The two pins below carry the left and right channels of
audio. You may remember from Chapter 4.3 that rack lters can be used to support lters with more
than just one stereo output. This is because you can specify the number of input and output audio pins
a rack offers. Note that racks can only support one MIDI input and output pin, however. We will look
more closely at racks with multiple pins later in this chapter.
In addition you will notice a name tab to at the top-left of the rack editor, each rack in the edit will be
shown as a tab here. Clicking the name tab will bring the corresponding rack to the fore.
New rack: This button displays a pop-up menu from which you can create a new rack lter.
•
Create new empty rack: Select this option to creates a standard stereo in/out rack lter.
•
Load a preset rack: Select this option to create a new rack lter and load the selected rack-pre-
set into it. If no rack-presets have been saved, this option is unavailable.
Show one rack/two racks: Use this button to toggle between one large editor canvas and two smaller
ones. Normally, you will only want to work with one rack at a time, but sometimes you might want to
compare or copy/paste between two racks.
