8 <dfn>a2jmidid</dfn> is an application that bridges between the system
9 <abbr title="Musical Instrument Digital Interface">MIDI</abbr> ports and
10 <abbr title="JACK Audio Connection Kit">JACK</abbr>.
13 First you should make sure that there is no ALSA sequencer support enabled
14 in JACK. To do that open QJackCtl's <kbd class="menu">Setup</kbd> window.
17 Set <kbd class="menu">Settings > MIDI Driver</kbd> to <kbd
18 class="input">none</kbd>.
19 Then uncheck the <kbd class="optoff">Misc > Enable ALSA Sequencer
20 support</kbd> option.<br />
21 Now it's time to restart your jack server before going on.
24 <h3>Check for a2jmidid availability</h3>
26 First, check whether a2jmidid is already installed in your system. After
27 starting your JACK server, go to the command line and type
29 <kbd class="cmd lin">a2jmidid -e</kbd>
31 If a2jmidid does not exist, install it with the software manager of your
32 Linux distribution and try again.
35 <h3>Check surface control MIDI ports</h3>
37 After starting a2jmidid, your control surface MIDI ports should appear in
38 qjackctl under <kbd class="menu">Connections > MIDI > a2j</kbd>.
41 You can now add <kbd class="input">a2jmidid -e</kbd> as an "after start-up" script in the <kbd
42 class="menu">Setup > Options</kbd> tab of QJackCtl, so that it is
43 started automatically whenever you start JACK.
