<p>
A <dfn>patch change</dfn> is Ardour's description for a combination
of MIDI program change and bank select messages, that (typically)
instruct a synthesizer or sampler to select a different sound to use
on a particular channel.
</p>
<p>
Patch changes are shown within MIDI regions as small rectangles or
<dfn>flags</dfn>, as shown below:
</p>
<h2>Inserting Patch Changes</h2>
<p>
Ensure that the
<a href="/ardours-interface/the-edit-point-control/">edit point</a> is
located where you want the patch change to be (within an existing
MIDI region). Context click, and from the MIDI region's context menu,
select <kbd class="menu">MIDI &gt; Insert Patch Change</kbd>. A
dialog will appear allowing you to set the bank and program values.
</p>
<h2>Modifying Patch Changes</h2>
<p>
Context-clicking on a patch change will bring up the same dialog that
was used to create it, allowing you to modify the program and/or bank
numbers.
</p>
<p>
You can also use the mouse wheel: <kbd class="mouse">&uArr;</kbd>/<kbd
class="mouse">&dArr;</kbd> on the patch change will alter the program
number, <kbd class="mouse mod1">&uArr;</kbd>/<kbd
class="mouse mod1">&dArr;</kbd> will modify the bank number.
</p>
<h2>Moving Patch Changes</h2>
<p>
Just <kbd class="mouse">Left</kbd>-drag on the patch change to move it
around.
</p>
<h2>Removing Patch Changes</h2>
<p>
Put the mouse pointer into the rectangular area, and press <kbd>Del</kbd>
or use the delete mouse button operation. This will remove the patch change
(the operation can be undone).
