Common DSP Control Parameters

Common DSP Control Parameters
The type of DSP function available for any function block depends on the algorithm. Some of
the specialized functions like the PANNER are always located just before the final AMP
function. Others, like the three-input functions, appear only in algorithms that are structured for
three-input functions.
You can change the nature of each layer of a program simply by assigning different DSP
functions to the layer's algorithm. Your level of control goes much deeper than that, however.
Each DSP function has one or more inputs to which you can patch a variety of control sources to
modify the behavior of the DSP functions themselves. These control inputs are represented by
the arrows pointing down at the blocks that make up the algorithm. For each input arrow,
there's a corresponding control-input page that you can select with the five special soft buttons
we mentioned above (PITCH, and F1–F4). All of the DSP functions have at least one control
input, but many of them have two or even three inputs.
The parameters on the various control-input pages are very similar; in fact, there are six
parameters that appear on almost every page. Consequently we refer to them as the common
DSP control parameters. Although the parameters on the control-input pages differ slightly
from function to function, you can expect to see some or all of the common DSP control
parameters whenever you select the control-input page for any of the DSP functions.

Initial Setting Parameters

These have no input, but set the overall level for the function, the starting point from which the
other parameters modulate the function.
• Coarse adjust (Coarse)
• Fine adjust (Fine)

Hard-wired Parameters

These always take their input from MIDI events (either the K2661 or an external MIDI
controller)—specifically the note number and the attack velocity values of each Note On event.
• Key tracking (KeyTrk)
• Velocity tracking (VelTrk)

Programmable Parameters

These can accept any control source as their input, and have related parameters for further
control.
• Source 1 (Src1)
• Source 2 (Src2)
Take a look at the PITCH page, as an example—we'll look at how these six control parameters
are used in the pitch control function. If you're not already on the PITCH page, you can get there
