+<h2>What Can Ardour Do With MIDI?</h2>
+<p>
+ <dfn><abbr title="Musical Instrument Digital Interface">MIDI</abbr></dfn>
+ is a way to describe music data and to control music hardware and
+ software. Ardour can import and record MIDI data, and perform a
+ variety of editing operations on it. Furthermore, MIDI can be used to
+ control various functions of Ardour.
+</p>
+<p class="note">
+ Ardour does not include a <dfn>synthesis engine</dfn> to produce audio
+ from MIDI data, but relies on plugins or external hard- and software
+ for the task. This can be a stumbling block for first time users who
+ expect MIDI input to result in audio output by default.<br />
+ Please see the section on working with plug-ins for more information on
+ turning MIDI data into audio output.</p>
+
+<h2>MIDI Handling Frameworks</h2>
+<p>
+ Ardour supports various ways of sending and receiving MIDI data:
+</p>
+
+<h3>CoreMIDI</h3>
+<p>
+ <dfn>CoreMIDI</dfn> is the standard MIDI framework on OSX systems.
+ It provides drivers for MIDI hardware and libraries needed by MIDI
+ software clients.
+</p>
+
+<h4>ALSA MIDI</h4>
+<p>
+ <dfn><abbr title="Advanced Linux Sound API">ALSA</abbr> MIDI</dfn>
+ is the standard MIDI framework on Linux systems. It provides drivers
+ for MIDI hardware and libraries needed by MIDI software clients.
+</p>
+<p>
+ The <dfn>QJackCtl</dfn> control software displays ALSA MIDI ports
+ under its "ALSA" tab (it does not currently display CoreMIDI ports).
+</p>
+
+<h4>JACK MIDI</h4>
+
+<p>
+ <dfn><abbr title="JACK Audio Connection Kit">JACK</abbr> MIDI</dfn>
+ is a framework used to comunicate between JACK MIDI software clients.
+ It provides zero jitter and a fixed latency of one <dfn>period</dfn>,
+ the same latency as for JACK audio.
+</p>
+<p>
+ JACK MIDI ports show up under the <kbd class="menu">MIDI</kbd> tab in
+ QJackCtl.
