+ Extenders will require a custom file as there are no combinations listed
+ at this time. The best way is to start with the mc.device file and copy it
+ to a new name such as xt+mc.device and then edit that file. It is best to
+ name the file with the order the devices are expected to be used in as
+ the position of the master device is specified in this file.
+</p>
+<p>
+ The two lines of interest are:
+<p>
+<pre>
+ >Extenders value="0"/>
+ >MasterPosition value="0"/>
+</pre>
+<p>
+ Add these two lines if they are not present. The <code>Extenders</code>
+ value is the number of extenders used and should not include the master in
+ that number. That is, it should be the total number of units minus 1. The
+ <code>MasterPosition</code> value is the position from left to right where
+ the master unit (with the master fader) is, starting at 0. So if there are
+ three surfaces, <code>MasterPosition</code> with value 0 would be master
+ on the left, <code>MasterPosition</code> with value 1 would be master in
+ the middle and <code>MasterPosition</code> with value 2 would be master on
+ the right.
+</p>
+<p>
+ If the <code>MasterPosition</code> value does not properly match the
+ physcal position and MIDI port, the master fader and global controls will
+ not work. The master unit will act like an extender.
