MIDI N   -> Quantize  +75%
--------------------------
Quantize divides the input signal into ~16 parts at 98% input.  For
example, given these inputs, you'll get this output:
0-7 in   - 0 out
8-15 in  - 8 out
16-31 in - 16 out
etc.

>>>Wait a second, you lost me.  If quantize outputs a 16 part signal for 
98% input, then how can a 16-31 input value provide the same thing? <<<<

Now that we have a stair step input signal in response to the
continuous input, we can route that to pitch.  Normally to get an
octave on the XL-7, you would route the controller to Pitch at 38% and
FinePitch at 6%. 

>>>>Interesting, the manual only states that the pitch should be 38%, 
doesn't mention anything about fine pitch too. <<<<

Yeah, I know, why the previous engineers didn'tchoose a round number (like 
50% to Pitch = one octave) I don't know,
but that's the way it goes. 

>>>Something I've always wondered! Don't make it easy like 24 or 12, no 
no, make it something odd like 38! :) <<<

Now for the hard stuff:
I just realized I wrote this up wrong.  The following cords are what I had 
in my XL-7, the ones I posted in the previous post are not.

>>>You're fired! <<<

So anyway, here's a breakdown of what this chunk of cords does.
Quantize -> Gain4X   +100%
Quantize -> Lag0In   +100%
Lag0     -> Gain4X   -100%
--------------------------
This creates an approximate differentiator.  For those who didn't do so 
hot in Calculus (like me; calc kicked my ass) a differentiator creates a 
signal that is proportionate to how quick the input signal changes. 

>>>So what does the Gain4x do to the Quantize amount(you first cord 
above), turn it into 64 discrete steps? This almost looks like recursive 
modulation to me....<><<

Try using one to increase chorus when changing pitch to get a symphonic 
type sound.

>>>Care to draw it out?  Sorry, the above example is still a little fuzzy 
to me. <<<

Go program something!  Enjoy the fact that your ROMpler is more of a synth 
than some VAs!  =)

>>>Thanks man, it's examples of the more out there modulation options that 
help me to grasp what they can do.  BTW, how the hell did you come up with 
this stuff, did tehy send you to an Emu synth programming school? :) To 
think paying attention in calc could have actually helped me be a better 
synthesist!  Doh!<<<
