<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>, with a vertical line showing where in the region
(hence "when") this patch change happens.
</p>
<h2>Inserting Patch Changes</h2>
<p>
To insert a patch change, the <a href="@@edit-point-control">edit point</a>
should be located where the patch change should be (within an existing MIDI
region). When <kbd class="mouse">right</kbd> clicking, and from the MIDI
region's context menu, selecting <kbd class="menu">MIDI &gt; Insert Patch
Change</kbd>, a dialog appears allowing 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 to modify the program and/or bank
numbers.
</p>
<p>
The mouse wheel can also be used: <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>-dragging the patch change moves it
around.
</p>
<h2>Removing Patch Changes</h2>
<p>
Pressing <kbd>Del</kbd> with the mouse pointer into the rectangular area, or
using the <kbd class="menu">delete</kbd> mouse button operation will remove the
patch change (the operation can be undone).
