Chapter 22 Control Surface Support 659
Note: The placement of your control surface units in relation to each other should be
the same onscreen as in the real-world. Simply drag ’n drop the desired icon
horizontally in your Control Surface Group to do so.
Device parameters
Each control surface unit must be connected to an independent MIDI In and Out port.
The automatic setup or Scan procedure should have automatically found, and set, the
correct MIDI In/Out port settings for each unit.
In the event that the MIDI In or Out port identification is incorrect, you can manually
select the appropriate one for the unit. To do so, click-hold on the MIDI Input and
Output pull-down menus, and select the appropriate port(s) of your MIDI interface.
Some devices allow you to define a device ID (or global/basic channel). This can be set
in this area. Module name, model name and firmware version are also displayed in the
device parameters.
Special Parameters
Some control surfaces may allow the definition of “special” parameters. An example of
this is fader touch sensitivity. Such parameters can be found in the Special Parameters
area. A detailed description can be found in the documentation of the particular
control surface plug-in.
Control Surface Group Parameters
The following parameters are shown in the Setup window. They apply to the Control
Surface Group associated with the selected device, and allow you to set each group up
to meet your needs. This facility is of great benefit when multiple Control Surface
Groups have been created.
Many (if not all) Control Surface Group parameters can also be changed directly from
the control surface. The parameter display in the Setup window is for information
purposes only.
Any changes to settings (made here, or on the control surface) are saved in a
preferences file, which is independent of the Logic program preferences: it’s named
“com.apple.Logic.cs”, and is located in your $/home directory/Library/Preferences.
