<p>
Finds an unused MIDI locale (bank:program number pair) in a patch
base object. The way in which MIDI bank and program numbers are
used is implementation dependent. Percussion instruments often
affect the bank parameter (for example SoundFont uses bank 128 for
percussion presets). On input the <em class="parameter"><code>bank</code></em> and <em class="parameter"><code>program</code></em> parameters
set the initial locale to start from (set to 0:0 to find the first
free value). If the <em class="parameter"><code>percussion</code></em> parameter is set it may affect
<em class="parameter"><code>bank</code></em>, if its not set, bank will not be modified (e.g., if bank is
a percussion value it will be used). The exclude parameter can be
set to a child item of <em class="parameter"><code>base</code></em> to exclude from the list of "used"
locales (useful when making an item unique that is already parented
to <em class="parameter"><code>base</code></em>). On return <em class="parameter"><code>bank</code></em> and <em class="parameter"><code>program</code></em> will be set to an unused
MIDI locale based on the input criteria.</p>
