I don't completely understand this TRIG SELECT business.  I understand
what it *does*, but not how to set it up.  The manual is a little
unclear in this section and makes it seem as though you can sequence
the trig select setting with parameter locks.  Is this right?  If so,
how do you do it?  Also, can you change the TRIG SELECT setting for
individual tracks?  So far, I can only change it globally.

It's a great idea, though.  It makes the arpeggiator REALLY
interesting (as if it needs any help; that thing's awesome!).

Anyway, thanks in advance for the help!
Joe.
