4 menu_title: Working With Extenders
8 There are currently 5 devices preconfigured to work with extenders.
9 Two of them are for one master and one extender with the master on the
10 right side or master on the left side. There are three presets for a
11 master and two extenders with the master on the left, in the center
12 and on the right. While these files will work for many uses there may
13 be cases where a custom device profile makes more sense.
14 The best way is to start with the *.device file in the <a
15 href="/appendix/files-and-directories/">
16 sytem config sub directory mcp</a> that matches your
17 master device and copy it to a new name such as xt+mc.device in the
18 <a href="/appendix/files-and-directories/">
19 user config sub directory mcp</a> and then edit that file. It is best to
20 name the file with the order the devices are expected to be used in as
21 the position of the master device is specified in this file.
24 The three lines of interest are:
27 <Name value="Device name"/>
28 <Extenders value="0"/>
29 <MasterPosition value="0"/>
32 Add any lines that are not present.
35 The <code>Name</code> value should be a unique name so it is obvious
36 in the list of devices (so change it).
39 The <code>Extenders</code>
40 value is the number of extenders used and should not include the master in
44 When an <code>Extenders</code> value of greater than 0 is used, extra midi
45 ports will appear for the extenders to be connected to. The MIDI ports
46 for the controllers will be named <code>mackie control in/out</code> for
47 the master, <code>mackie control in/out ext #*</code> where * is the
48 position of the extender from left to right. So for a master in the middle
49 with an extender on either side, the ports from left to right will be
50 mackie control in/out ext #1, mackie control in/out and mackie control in/out ext #3.
53 If using the MCP GUI to connect surfaces the top surface is the leftmost
54 and the bottom is the rightmost. At the time of writing the top is always
55 labeled as the main (master) surface even if the leftmost surface is an
59 The <code>MasterPosition</code> value is the port number the master unit
60 (with the master fader) is connected to. So if there are three surfaces,
61 <code><MasterPosition value="1"/></code> will expect the master on
62 the left, <code><MasterPosition value="2"/></code> would be master
63 in the middle and <code><MasterPosition value="3"/></code> would be
67 The default value of <code><MasterPosition value="0"/></code> has
68 the same effect as <code><MasterPosition value="1"/></code>.
71 If the <code>MasterPosition</code> value does not properly match the
72 physcal position and MIDI port, the master fader and global controls will
73 not work. The master unit will act like an extender.
