This includes fixing em-dashes, badly spaced colons, various
misspellings, removal of spurious {% %} constructs, conversion of <br />
to <br> (still too many <br>s kicking around), and initial light cleanup
of a few sections that caught my eye.

Ardour is capable of being used to both record and deliver MIDI
|
|
"scene" automation. These are MIDI messages typically used to switch
|
|
presets or "scenes" on a variety of external equipment (or
|
|
software), including lighting and other audio/video tools. A common
|
|
use case is to automatically change presets between songs or to change
|
|
lighting conditions based on a specific position on the timeline.
|
|
</p>
|
|
<p>
|
|
Each change from one scene to another is represented by a marker in
|
|
the "Marker" bar.
|
|
</p>
|
|
<p>
|
|
Technically, scene changes are delivered as a combination of bank and
|
|
program change MIDI messages. MIDI allows for 16384 banks, each with
|
|
128 programs.

<h2>Recording Scene Changes</h2>
|
|
|
|
<p>
|
|
Ardour has a dedicated MIDI port named "Scene In". Connect this port
|
|
to whatever source(s) of MIDI scene (bank/program change) messages you
|
|
wish to record.
|
|
</p>
|
|
<p>
|
|
Whenever the global record enable button is engaged and Ardour's
|
|
transport is rolling, a new marker will be created for each scene
|
|
change message received via the "Scene In" port.
|
|
</p>
|
|
<p>
|
|
If 2 different scene changes are received within a certain time
|
|
period, only the later one will be recorded as a new marker. The
|
|
default threshold for this is 1 millisecond.
|
|
</p>
|
|
<p>
|
|
If a scene change message is received while the playhead is close to
|
|
an existing marker with an associated scene change, the recording
|
|
process will alter the scene change in the existing marker rather than
|
|
adding a new one. The default threshold for this "proximity" test is 1
|
|
millisecond.
|
|

<h2>Playing back Scene Changes</h2>
|
|
|
|
<p>
|
|
Ardour has a dedicated MIDI port named "Scene Out". Connect this port
|
|
to wherever you wish to send MIDI scene (bank/program change) messages.
|
|
</p>
|
|
<p>
|
|
When the global record enable button is
|
|
<em>not</em> enabled, the relevant message(s) will be sent via the
|
|
"Scene Out" port as the playhead rolls past each marker with a scene
|
|
change associated with it.
