Real-time Control of KDFX
Setting up FXMods

As usual in the Program Editor, you can also get to these pages directly from the KDFX page or
one of the FXMOD pages: select one of those parameters as a Source, and then press
Edit .
Tempo-based parameters
There are several different ways KDFX can respond to tempo information, from the internal
sequencer or an external one. These are discussed later in this chapter.
Depth
The Depth parameter lets you specify the amount of change in value that the real-time control
will make to the target Parameter, using the Adjust value as a minimum or starting point. The
amount of change can be positive or negative, and Depth values are displayed in the context of
the selected Studio Parameter: seconds, dB, %, Hz, cents, etc.
At the maximum setting of the Source (for example, Mod Wheel all the way up), the value of
the parameter = Depth. So if the parameter is Out Gain, the Adjust is 1.0 dB, the
Source is Mod Wheel, and the Depth is 4.0 dB, then at the Mod WheelÕs highest point, the
output gain will be 5.0 dB.
For Source values less than maximum, the formula is: parameter = (Depth x Source),
where the Source is considered to be varying between 0 and 1 (or in some cases, such as Pitch
Wheel, between -1 and +1). So using the same example, when the Mod Wheel is halfway up
(MIDI value 64), the gain is 1.0 + (4.0 x 1/2) = 3.0 dB, and when it is all the way down (MIDI
value 0), the gain is 1.0 + (4.0
x 0) = 1.0 dB.
The formula works the same way for negative Depth values. Given the same example, but with
a Depth of -4.0dB, at the Mod WheelÕs minimum point, the gain will be 1.0 dB; at its halfway
point it will be 1.0 + (-4.0 x 1/2) = -1.0 dB; and at its maximum point it will be -3.0dB.
Showing whoÕs in control
When you are in Program or Setup mode and you look inside the current Studio or its FX
Presets, any parameters that are under FXMod control will not display numerical values, but
instead will say ÒFXModÓ.
DonÕt touch any of those parameters for nowÑweÕll explain why in
a moment.
☛
Note that if you look at the Studio when FX Mode is in ÒMasterÓ, the FXMods will not be
displayed, because the FXMods are not in effect! DonÕt get confused by thisÑthe FXMods will
return when you go back into Program or Setup mode.
