-  On Linux systems, <dfn>QJackCtl</dfn> control software displays ALSA MIDI
-  ports under its "ALSA" tab (it does not currently display CoreMIDI ports).
-  By contrast, JACK MIDI ports show up under the <kbd class="menu">MIDI</kbd>
-  tab in QJackCtl. However, when Ardour is using jackd for audio in and out
-  the alsa MIDI ports are not accessable. When Ardour is using ALSA for audio
-  in and out then only alsa MIDI ports are accessable.

+  alternate audio system which Ardour can utilize for both audio and

+  and is now considered an advanced use case which is not recommended
+  for most users.  Users with a need to use JACK for audio routing

-  By default, JACK will <strong>not</strong> automatically detect and use
-  existing MIDI ports. One of several ways of <dfn>bridging</dfn> between
-  the native MIDI frameworks (e.g. CoreMIDI or ALSA) and JACK MIDI must be
-  chosen, as described in the following sections.
