+ It is no longer nessessary to use jackd as a backend for Ardour in Linux.
+ In fact with the spread of LV2 plugins, almost all workflows in Ardour work
+ well with the ALSA backend. When using the ALSA backend for Ardour, Ardour
+ will see all MIDI ports that ALSA sees without any user setup. However, should jackd
+ need to be used, the rest of this page is valid.

+ The right approach for using MIDI on Linux depends on which version of JACK
+ is in use. The world divides into:

+<table class="dl">
+ <tr><th>Systems using JACK 1, versions 0.124 or later</th>
+ <td>On these systems, JACK must be started with the <code>-X alsa_midi</code>
+ server argument. To support legacy control applications, the <code>-X
+ seq</code> argument to the ALSA backend of JACK can also be used to get the
+ exact same results.</td></tr>
+ <tr><th>All others</th>
+ <td>Using a2jmidid acts as a bridge between ALSA MIDI and JACK. The <code>-X seq</code>
+ or <code>-X raw</code> arguments should <em>not</em> be used—the timing and
+ performance of these options is unacceptable.</td></tr>
