<h2>The transport controls</h2>
|
|
|
|
<p>
|
|
The <dfn>Transport Bar</dfn> groups all the actions regarding the control of
|
|
playback and recording.

|
|
<p>
|
|
This bar is made of (from left to right):
|
|
</p>
|
|
|
|
<dl>
|
|
<dt>Midi Panic</dt><dd>Immediately stops all midi output.</dd>
|
|
<dt>Enable/disable Audio Click</dt><dd>Toggles (on/off) a click track (metronome)
|
|
along the <a href="@@tempo-and-meter">tempo</a>. Right clicking brings up the
|
|
<kbd class="menu">Click</kbd> submenu from the Preferences. Scrolling with
|
|
the mouse wheel adjusts the gain of the click.</dd>
|
|
<dt>Go to Start of the Session</dt><dd>Jumps back at the beginning of the session,
|
|
as defined by the <a href="@@working-with-markers">start marker</a>.</dd>
|
|
<dt>Go to End of the Session</dt><dd>Jumps forward to the end of the session,
|
|
as defined by the <a href="@@working-with-markers">end marker</a>.</dd>
|
|
<dt>Play Loop Range</dt><dd>Repeats the defined <a href="@@controlling-playback">loop</a>
|
|
as defined by the <a href="@@the-loop-range">Loop range</a>, until the "Stop
|
|
playback" button is pressed. Clicking the "Play loop Range" button while
|
|
already active switches to normal Play mode, which exits the loop without
|
|
stopping and restarting playback.</dd>
|
|
<dt>Play Range/Selection</dt><dd>If a range has been defined using the Range
|
|
Mode button, plays the range, of if an audio or MIDI region is selected,
|
|
plays this region. In both cases, the playback stops at the end of the range
|
|
or selected region.</dd>
|
|
<dt>Play from playhead</dt><dd>Starts the playback and optionally record (more
|
|
below).</dd>
|
|
<dt>Stop</dt><dd>Whatever the playing mode (loop, range, …) stops all
|
|
playback. Depending on other settings, some effects (like chorus or reverb)
|
|
might still be audible for a while.</dd>
|
|
<dt>Toggle Record</dt><dd>Global switch button to activate/deactivate recording.
|
|
While active, the button blinks red. The button doesn't start recording by
|
|
itself: if one or more tracks are marked as record-enabled, pressing the
|
|
"Play from Playhead" starts recording on those tracks. See
|
|
<a href="@@record-setup">Recording</a>.</dd>
|
|
</dl>
|
|
|
|
<p class="note">
|
|
All these actions are bound to keyboard shortcuts, which allows for speedier
|
|
use and more focused work.
|
|
</p>
|
|
|
|
<p class="note">
|
|
If you synchronize Ardour with other devices then some or all of these control
|
|
methods may be unavailable—depending on the synchronization protocol,
|
|
Ardour may respond only to commands sent from its master device(s).
|
|
</p>
|
|
|
|
<p>
|
|
Under these buttons is the <dfn>Shuttle Speed Control</dfn> that allows to scrub
|
|
through the audio quickly. The slider decides the playback speed : the further
|
|
from the center it is set, the faster the playback will scrub in both directions.
|
|
</p>
|
|
<p>
|
|
The Shuttle Speed Control supports 2 operating modes, that can be chosen with
|
|
right click > Mode:
|
|
</p>
|
|
<ul>
|
|
<li><dfn>Sprung mode</dfn> that allows for a temporary scrub: it only scubs
|
|
while the mouse is left clicked on the control.</li>
|
|
<li><dfn>Wheel mode</dfn> that allows to set a playback speed until the "Stop"
|
|
button is pressed, which stops the playback and resets its speed.</li>
|
|
</ul>
|
|
|
|
<p>
|
|
On the left of the slider is the positional sync button (which might show <dfn>Internal</dfn>,
|
|
or <dfn>MTC</dfn> or several other values), than can be used to control whether or not the
|
|
transport position and start is controlled by Ardour, or by an external positional
|
|
synchronization source, such as MIDI Time Code (MTC), Linear Time Code (LTC) or JACK
|
|
(see <a href="@@timecode-generators-and-slaves">Timecode Generators and Slaves</a>).
|
|
</p>
|
|
<p>
|
|
The current playback status (Stop, Play, or speed %) is shown on the right of
|
|
the speed slider.
|
|
</p>
|
|
|
|
|
|
<h2>Using Key Bindings</h2>
|
|
<p>
|
|
Ardour has many available commands for playback control that can be bound
|
|
to keys. Many of them have default bindings, some do not, so the list below
|
|
shows both the default bindings and internal command names for some of them.
