POINTs does not mean "no effect". The Tracking Generator's default
settings - or the Values that produce no effect - are as follows:
POINT 1
=
0
POINT 2
=
1 5
POINT 3
=
31
POINT 4
=
47
POINT 5
=
63
When the POINT Values have been set to these values, TRACK is
said to have a LINEAR output. The input is the same as the output -
no effect, no change. When using TRACK, use these Values as a
place to start from in getting the result you want. Changing any one
of these Values changes the curve of the Tracking Generator and
whatever you selected as the INPUT will behave in a different way.
Let's take a look at how TRACK accomplishes this. Read on.
Using the TRACKING GENERATOR
You can think of TRACK as having two components: the modulation source
that you want to change (labelled IN PUT) and the re-shaping functions
(labelled POINTs 1 through 5) which make up the generator's curve and
thus its OUTPUT. So, when using TRACK, assign it to its destination like
you would any other modulation source (see the section covering MATRIX
MOD). Then select the actual modulation source you want to use for the
INPUT. The real magic begins when we experiment with the five POINT
values.
Here's an example:
A very basic and easy to hear demonstration of how the Tracking Generator
re-shapes a modulation source is to modulate the pitch of DC01 by an LFO.
We'll use a slow UPSAW (positive Sawtooth) waveform that will produce an
effect of the note having a smooth rise in pitch with a sharp dropoff at its
peak. We are going to use TRACK to put an audible "hump" in the rising
portion of the wave. Let's set up the patch as follows:

without interference from other modulations, set up the

STEP
3:
Type in the number " 1 6" on the KEYPAD to display
DC02's WAVE SELECT.
STEP
4:
Select the VALUE Parameter.
STEP
5:
Press the << button on the Keypad so that the display
reads
OFF.
We have just turned off the output of DC02
so that in our experimentation with TRACK we will only be
listening to DC01 .
