Advanced KDFX
Real-time Control of KDFX
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 (see Tempo-based Control of
KDFX on page 15-32).
Depth
The Depth parameter lets you specify a range of change in values that the real-time control will
make, using the Adjust value as a minimum or starting point. This range can be positive or
negative, and the values are displayed in the context of the 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 = Adjust + 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 Wheel's highest point, the output gain will
be 5.0 dB.
For Source values less than maximum, the formula is: parameter = Adjust + (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 Wheel's minimum point, the gain will be 1.0 dB; at its halfway
point it will be -1.0 dB (1.0 + (-4.0 x 1/2)); and at its maximum point it will be -3.0dB.
Showing Who's 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 FXMod. Don't touch any of those parameters for now—we'll explain why in a
moment.
Note that if you look at the studio when FX Mode is in Master, the FXMods will not be displayed,
because the FXMods are not in effect! So don't get confused.
Breaking the Links
When FX Mode is Program (or Setup) and you are in the Studio Editor, if you change a
parameter that has been assigned an FXMod, it breaks the link—the parameter is no longer
under FXMod control, but is now a static value. If you now save the studio (either in the same
location or a different one), the link stays broken. However, if you leave the studio without
