    Introduction
 
Control Surface Plug-ins
Supported control surfaces communicate with Logic Pro via special plug-in files that 
are installed along with Logic Pro. The plug-in files are located in the /Contents/MIDI 
Device Plug-ins subfolder of the Logic Pro application bundle. To view the bundle 
contents, Control-click the Logic Pro application icon, and choose Show Package 
Contents from the menu. Logic Pro also checks for control surface plug-ins installed in 
the (optional) /Library/Application Support/Logic/MIDI Device Plug-ins and ~/Library/
Application Support/Logic/MIDI Device Plug-ins (the “~” denotes your user home 
directory) folders. 
When new control surface plug-ins are released independently from a Logic Pro update 
(or supplied directly by the device manufacturer), please place them in the folders 
described above (or as advised in the documentation supplied with the plug-in). 
About Software and Firmware
Most control surfaces depend on Logic Pro for their functionality, and cannot be 
operated if Logic Pro is not running. They do not provide any additional functionality 
that is not available in Logic Pro itself. One advantage of this approach is that as new 
functions are added to Logic Pro, or as you create new assignments, your control 
surface will be able to access and control them.
Most control surface units do include a form of software called firmware. Firmware is 
similar to the low-level boot software found in your computer, cellular phone, iPod, and 
so on. 
New behaviors, such as improved control of motorized faders and changes to the 
display, can be provided by firmware updates. You should periodically check the 
manufacturer’s website for your device, to check for updates that may enhance use or 
performance.
The firmware is usually stored on an EEPROM (Electronically Erasable Programmable 
Read-Only Memory) chip. It can often be updated via a simple MIDI dump procedure, 
in the form of a MIDI file. Should new firmware become available, you can simply 
download the appropriate MIDI file and play it (from Logic Pro) to your control surfaces, 
which will be updated accordingly. The steps required to perform a firmware update 
will be outlined in the documentation that accompanies the MIDI file. Please read this 
before attempting any update.
Note:  Some control surfaces may require that you physically replace the chip for 
firmware updates. Please contact the manufacturer of your device for details.
