8 A <dfn>patch change</dfn> is Ardour's description for a combination
9 of MIDI program change and bank select messages, that (typically)
10 instruct a synthesizer or sampler to select a different sound to use
11 on a particular channel.
14 Patch changes are shown within MIDI regions as small rectangles or
15 <dfn>flags</dfn>, with a vertical line showing where in the region
16 (hence "when") this patch change happens.
19 <h2>Inserting Patch Changes</h2>
21 To insert a patch change, the <a href="@@edit-point-control">edit point</a>
22 should be located where the patch change should be (within an existing MIDI
23 region). When <kbd class="mouse">right</kbd> clicking, and from the MIDI
24 region's context menu, selecting <kbd class="menu">MIDI > Insert Patch
25 Change</kbd>, a dialog appears allowing to set the bank and program values.
28 <h2>Modifying Patch Changes</h2>
30 Context-clicking on a patch change will bring up the same dialog that
31 was used to create it, allowing to modify the program and/or bank
35 The mouse wheel can also be used: <kbd class="mouse">⇑</kbd>/<kbd
36 class="mouse">⇓</kbd> on the patch change will alter the program
37 number, <kbd class="mouse mod1">⇑</kbd>/<kbd
38 class="mouse mod1">⇓</kbd> will modify the bank number.
41 <h2>Moving Patch Changes</h2>
43 Just <kbd class="mouse">Left</kbd>-dragging the patch change moves it
47 <h2>Removing Patch Changes</h2>
49 Pressing <kbd>Del</kbd> with the mouse pointer into the rectangular area, or
50 using the <kbd class="menu">delete</kbd> mouse button operation will remove the
51 patch change (the operation can be undone).
