The tracking generator lets you create your own curves for the 
modulation sources.  This allows for non-linear effects.  For 
instance, as a source increases in amplitude, the destination can be 
affected first negatively, then positively, and then negatively again. 
 
The inputs for the tracking generator–like those for the S&H 
generator–are the same as the Modulation Matrix’s modulation 
sources (discussed later).  See page 92 for a list of those inputs. 
 
Grid 
The input to the Tracking Generator is quantized to either 12 or 
16 points above and below 0.   
 
Point x 
After you’ve created your grid, you can cycle through each point 
and set its value from -100% to +100%.   
 
An example should help clarify the concept: 
 
 
 
 
 
 
At the left, 16 points are indicated.  This is the number of positive 
points.  There are 32 points total, if you count the negative ones.  
Indeed, the display shows 32 points–16 each to the left and right 
of the y axis.   
 
Now, what’s displayed is a pretty radical tracking generation.  As 
you can see, before the midpoint of this source’s range, increasing 
values are intercepted by the tracking generator and turned into 
wildly non-linear, unexpected results.  When the midpoint is 
reached, the tracking generator locks the source’s output at 0 (its 
middle range).  Then, at the eighth positive point, the tracking 
generator gradually ramps up the source’s output value.  It holds 
steady for a while and then begins a gradual descent at the 
fourteenth positive point. How does all this sound?  Pretty weird. 
 
Remember, without the tracking generator, the source’s output 
would function normally–you’d see a diagonal line rising from the 
bottom left to the top right, without interruption.  The purpose of 
the tracking generator is to intercept and regenerate that line.
