2 <h2>What Can Ardour Do With MIDI?</h2>
4 <dfn><abbr title="Musical Instrument Digital
5 Interface">MIDI</abbr></dfn> is a way to describe musical
6 performances and to control music hardware and software.
8 <p>Ardour can import and record MIDI data, and perform a variety of
9 editing operations on it. Furthermore, MIDI can be used to control
10 various functions of Ardour.
13 <h2>MIDI Handling Frameworks</h2>
15 MIDI input and output for Ardour are handled by the same "engine"
16 that handles audio input and output.
21 <dd> <dfn>CoreMIDI</dfn> is the standard MIDI framework on OSX systems.
25 <dfn><abbr title="Advanced Linux Sound API">ALSA</abbr> MIDI</dfn>
26 is the standard MIDI framework on Linux systems.
30 <dfn>There is no single standard MIDI framework on Windows,
31 but Ardour can work with ASIO and others.
37 On Linux systems, <dfn>QJackCtl</dfn> control software displays ALSA MIDI
38 ports under its "ALSA" tab (it does not currently display CoreMIDI
39 ports). By contrast, JACK MIDI ports show up under
40 the <kbd class="menu">MIDI</kbd> tab in QJackCtl.
43 <h2>JACK MIDI Configuration</h2>
45 By default, JACK will <strong>not</strong> automatically detect and use existing MIDI
46 ports on your system. You must choose one of several ways
47 of <dfn>bridging</dfn> between the native MIDI frameworks
48 (e.g. CoreMIDI or ALSA) and JACK MIDI, as described in the sections
