This is a follow-up to my last post [100109 MMDigest].  There is
a new video on YouTube of Pat Metheny describing the automatic
instruments he is using for his Orchestrion tour.  It has some
more interesting details, including the fact that his guitar playing
can be processed to automatically play the tonal instruments
(i.e., strumming a G on his guitar could make a mallet hit a G
on a xylophone).  Very intriguing stuff.  The video is here:
