+ Sending MIDI messages to sampler channel</h3>
+ <p>The front-end can send MIDI events to specific sampler channel
+                     by sending the following command:
+ </p>
+ <p>
+                         </p>
+ <blockquote class="text">
+ <p>SEND CHANNEL MIDI_DATA &lt;midi-msg&gt; &lt;sampler-chan&gt; &lt;arg1&gt; &lt;arg2&gt;
+ </p>
+ </blockquote><p>
+ </p>
+ <p>Where &lt;sampler-chan&gt; is the sampler channel number
+                     as returned by the <a class='info' href='#ADD CHANNEL'>"ADD CHANNEL"<span> (</span><span class='info'>Adding a new sampler channel</span><span>)</span></a>
+                     or <a class='info' href='#LIST CHANNELS'>"LIST CHANNELS"<span> (</span><span class='info'>Getting all created sampler channel list</span><span>)</span></a> command,
+                     &lt;arg1&gt; and &lt;arg2&gt; arguments depend on the &lt;midi-msg&gt; argument, which
+                     specifies the MIDI message type. Currently, the following MIDI messages are supported:
+ </p>
+ <p>
+                         </p>
+ <blockquote class="text">
+ <p>"NOTE_ON" -
+                                 </p>
+ <blockquote class="text">
+ <p>For turning on MIDI notes, where &lt;arg1&gt;
+                                     specifies the key number and &lt;arg2&gt; the velocity
+                                     as described in the MIDI specification.
+ </p>
+ </blockquote>
+ <p>"NOTE_OFF" -
+                                 </p>
+ <blockquote class="text">
+ <p>For turning a currently playing MIDI note off, where &lt;arg1&gt;
+                                     specifies the key number and &lt;arg2&gt; the velocity
+                                     as described in the MIDI specification.
+ </p>
