+<p>
+ Ardour's handling of <dfn>MIDI editing</dfn> differs from most other DAWs
+ and MIDI sequencers.
+</p>
+
+<h2>Key features of Ardour MIDI handling</h2>
+<ul>
+ <li>
+ All editing is done in-place, in-window. There is no separate piano roll
+ window or pane. Edit notes right where you see them.
+ </li>
+ <li>
+ All MIDI I/O is done via JACK for sample accurate timing and maximal
+ efficiency when communicating with external software synthesizers.
+ </li>
+ <li>
+ Every MIDI track has its own JACK MIDI port for input; it may have an
+ arbitrary combination of audio and MIDI outputs, depending on the signal
+ processing in the track; the full flexibility of JACK connectivity is
+ present for MIDI just as it is for audio.
+ </li>
+ <li>
+ Full automation for MIDI tracks, integrated with the handling of all MIDI
+ CC data for each track.
+ </li>
+ <li>
+ Controllers (CC data) can be set to discrete or continuous modes (the
+ latter will interpolate between control points and send additional
+ data).
+ </li>
+ <li>
+ There is a Normal and a Percussive mode for note data editing.
+ </li>
+ <li>
+ The <dfn>scroomer</dfn> is a combination scroll/zoom tool for altering
+ the zoom level and range of visible MIDI data.
+ </li>
+</ul>
+
+<h2>Notable Differences</h2>
+<ul>
+ <li>
+ Fader (volume) control currently operates on transmitted MIDI data, not by sending CC
+ #7.
+ </li>
+ <li>
+ All note/data editing is per-region. There are no cross-region operations at this
+ time.
+ </li>
+ <li>
+ By default, copying a MIDI region creates a <dfn>deep link</dfn>
+ — both regions share the same data source, and edits to the contents of
+ one will affect the other. To break this link, select
+ <kbd class="menu">MIDI > Unlink from other copies</kbd> from the region
+ context menu, after which the selected region(s) will have their own copies
+ of <em>only</em> the data that they visually display on screen. You will not
+ be able to trim the region back its original length after an Unlink operation,
+ and the operation cannot be undone.
+ </li>
+</ul>
