You need to manually alter the MIDI In and Out port values (in the Device Parameter area
of the Setup window) to match those of the connected unit.
Note: You can reinitialize the support of all connected control surfaces by choosing
Logic Express > Preferences > Control Surfaces > Rebuild Defaults.
Creating Control Surface Groups
If you have multiple control surface units in your system, you can define how they relate
to each other, and create control surface groups. A control surface group consists of
multiple devices that you combine to create a single, unified virtual control surface.
You can create up to 20 control surface groups. Each group can consist of any number
of physical devices. The only limiting factor is the number of available MIDI In and Out
ports (or USB/FireWire “MIDI” ports, if you are using a USB or FireWire control surface).
You can independently determine the default behavior of each device in a group. For
more information, see the Device Parameters section.
To create a control surface group
1 Choose Logic Express > Preferences > Control Surfaces > Setup to open the Control
Surfaces Setup window.
2 In the Setup window, drag the icons of the control surfaces you want to group, so that
they form a single horizontal row.
The order of the icons from left to right defines the order in which tracks and parameters
are arranged and displayed on the devices.
To use two control surfaces independently
1 Choose Logic Express > Preferences > Control Surfaces > Setup to open the Control
Surfaces Setup window.
2 In the Setup window, arrange the icons for the control surfaces in separate rows—that
is, one above the other.
