+The right approach for using MIDI on Linux depends on which version of
+JACK you use. The world divides into:
+
+<dl>
+<dt>Systems using JACK 1, versions 0.124 or later</dt>
+<dd>On these systems, just start JACK with
+ the <code>-X alsa_midi server</code> argument. To support legacy control
+ applications, you can also use the -X seq argument to the ALSA
+ backend of JACK and get the exact same results.</dd>
+<dl>All others</dl>
+<dd>Use a2jmidid to act as a bridge between ALSA MIDI and JACK. Do
+ not use the -X seq or -X raw arguments - the timing and performance
+ of these options is not acceptable.
