+ 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 > 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">⇑</kbd>/<kbd
+ class="mouse">⇓</kbd> on the patch change will alter the program
+ number, <kbd class="mouse mod1">⇑</kbd>/<kbd
+ class="mouse mod1">⇓</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).
