How To Use This Patch:
	Bagpipes are rather unique instruments in that they
have a number of "drones" (2,3,4, whatever) which play the same
note continuously.  This means that a bagpipe CANNOT play in
any key and sound good- it has to play in the key it was 
tuned for.  
	
This being a synthesized bagpipe, we allow the user to tune
the drones to sound harmoniously by means of the modulation
wheel.  To tune to a key, press and hold the tonic note
and rotate the mod wheel slowly till you find the point of
least obnoxousness.  This patch has been set up so with the
mod wheel all the way DOWN, it's tuned in C.
	
How This Patch Works:
	OSC1 is used to generate the melody line.  Meanwhile,
OSC2 and 3 are negatively modulated with the keyboard
position, and hence do NOT track the keyboard position at all.
They play the same note (well, nearly the same note) across the 
entire keyboard.  In this particular patch, with the mod wheel
all the way down, they play C below middle C and G below middle C.  

	That gives us proper bagpipe tone (by the way, you can't
sample bagpipes.  The drones get all messed up and though it's
interesting, it isn't "bagpipey" when you play it).  Now,
bagpipes also slide into notes- there's a little "gulp" when
the player moves his arm.  So, we go into monophonic mode and
apply a little fast glide with GLIDE, and a little accent on
the attack with ENV1. 
 
Hints:
	Bagpipes don't have a particularly wide range.  This one
is no exception.  It plays best between middle C and one-and-a-half 
octaves up.
	AVOID BEATLES SONGS !  A friend of mine played "Penny Lane"
on this patch.  I had to spill ice cream into her lap to get her
to stop.  I never knew she could be so sadistic.  :-)
