Part 8: Editing Programs
TRACKING GENERATOR
The Tracking Generator function (press [9]) is used to scale a modulation source. For example, normally you could modulate the Amp (volume) of a sound using velocity; the harder you play, the louder the sound gets. The amount of change in volume is equal to the change in velocity; this is called linear control. If instead, however, you set the Tracking Generator’s input to “velocity”, and then routed the Tracking Generator to the Amp (using the Mod function), you can make your own customized velocity curve!
It might be helpful to think of the Tracking Generator (TG) as a fifth page available to the Mod function. When you choose it as your source on the first page of a Mod (let's say button [0], or Mod 1), you then need to go select the TG's input on button [9], page 1. In effect, the TG's input is its "Mod source", and the TG itself becomes a sort of "Mod destination". Modulation input is basically filtered through the TG before it reaches the actual Mod destination on page 2 of Mod 1.
The Tracking Generator divides the range of the input into 11 points
When selecting the Tracking Generator as a modulation source in the Mod Function, two choices will be available (TRACKGEN and STEPTRAK). When “TRACKGEN” is selected as the modulation source, the Tracking Generator functions normally, scaling its input as determined by its parameter settings.
When “STEPTRAK” is selected as a modulation source, the Tracking Generator’s output will be stepped, or interpolated. This means that instead of scaling the input in a linear fashion from point to point, the input is kept at each point’s value setting until it goes beyond the following point’s value setting, at which point it jumps to that setting. This feature is very useful in creating
