9 Ardour can import and record MIDI data, and perform a variety of editing
10 operations on it. Furthermore, MIDI can be used to control various functions
14 <h2>MIDI Handling Frameworks</h2>
17 MIDI input and output for Ardour are handled by the same "engine" that
18 handles audio input and output.
23 <td><dfn>CoreMIDI</dfn> is the standard MIDI framework on OSX systems.</td></tr>
25 <td><dfn><abbr title="Advanced Linux Sound API">ALSA</abbr> MIDI</dfn> is the
26 standard MIDI framework on Linux systems.</td></tr>
28 <td>There is no single standard MIDI framework on Windows, but Ardour
29 can work with ASIO and others.</td></tr>
33 On Linux systems, <dfn>QJackCtl</dfn> control software displays ALSA MIDI
34 ports under its "ALSA" tab (it does not currently display CoreMIDI ports).
35 By contrast, JACK MIDI ports show up under the <kbd class="menu">MIDI</kbd>
39 <h2>JACK MIDI Configuration</h2>
42 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.
