DrumVoice Polyphony

[Bryan Stanbridge]

Greetings,

This may help others writing music for percussion polyphony.  It took me
quite a bit of time to realize that the shorthand setup for simple
polyphony needed the s1*x to equal the number of whole note values in
the piece, instead of just a method of starting the DrumVoices.  I'd
suggest adding the following to the documentation (5.9.3 in v2.4.x,
6.4.3 in v2.5.x):

"The length of the created voice (s1*2 in this instance), should equal
the length of use in a piece.  For example, if you had 32 bars of 4/4,
the s1*2 should be replaced by s1*32."

This would probably be added after the figure following this text:

"The above example shows verbose polyphonic notation.  The short
polyphonic notation, described in [Polyphony], can be used if the
[DrumVoice]s are instatiated by hand first. For example:"

At the very least, here it is on the archives (I checked earlier to make
sure I'm not posting something that's already been said, but they were
down).  Hopefully it'll save someone the hour+ I've spent wondering
why all my polyphonic examples broke down after two bars.  ::sigh::

Cheers!

Bryan...
