<DL>
<DD>Sets the mute state for a track.  This method may fail for a number
 of reasons.  For example, the track number specified may not be valid
 for the current sequence, or the sequencer may not support this functionality.

<DL>
<DD>Sets the solo state for a track.  If <code>solo</code> is <code>true</code> 
 only this track and other solo'd tracks will sound. If <code>solo</code>
 is <code>false</code> then only other solo'd tracks will sound, unless no

<DL>
<DD>Registers a controller event listener to receive notification 
 whenever the sequencer processes a control-change event of the 
 requested type or types.  The types are specified by the
 <code>controllers</code> argument, which should contain an array of 
 MIDI controller numbers.  (Each number should be between 0 and 127,
 inclusive.  See the MIDI 1.0 Specification for the numbers that
 correspond to various types of controllers.)
 <p>
 The returned array contains the MIDI controller
 numbers for which the listener will now receive events.
 Some sequencers might not support controller event notification, in
 which case the array has a length of 0.  Other sequencers might 
 support notification for some controllers but not all. 
 This method may be invoked repeatedly. 
 Each time, the returned array indicates all the controllers
 that the listener will be notified about, not only the controllers
 requested in that particular invocation.<DD><DL>

<DL>
<DD>Removes a controller event listener's interest in one or more 
 types of controller event. The <code>controllers</code> argument
 is an array of MIDI numbers corresponding to the  controllers for 
 which the listener should no longer receive change notifications. 
 To completely remove this listener from the list of registered
 listeners, pass in <code>null</code> for <code>controllers</code>. 
 The returned array contains the MIDI controller
 numbers for which the listener will now receive events.  The
 array has a length of 0 if the listener will not receive
 change notifications for any controllers.<DD><DL>
