saving it, and go back to the FXMod pages of the Program Editor, the link automatically
reestablishes itself.
If you change the FX preset on an FXBus, the FXMod links to the preset on that bus may or may
not break. If the preset you're calling up uses the same algorithm as the preset you're leaving, the
links will stay intact. If it uses a different algorithm—even a similar one—the links will break.
On the other hand, if you are inside a preset, and you change its algorithm, that breaks the links.
Again, the links will be reestablished if you leave the preset without saving it.
Links to the Aux and Mix parameters on an FXBus do not get interrupted when you change the
FXpreset on that bus.
The same rule applies when you are on the KDFX page in a program or setup and you change
the studio. Links to the Input and Output pages and the Level parameters on the FXBus pages
will be retained, but links to processing parameters will be retained on a given FXBus only if the
algorithm inside the preset on that bus isn't changed.
What About Bus Overrides?
Bus overrides are transparent, as far as KDFX is concerned. Any FXMods that involve a
parameter inside an FX preset are set up directly between the program and the FX preset itself. If
the parameter happens also to be assigned a bus override, it doesn't make a difference to
KDFX—the program will control the parameter as if the bus override wasn't there.
However, bus overrides are still active within a studio, and changing a bus override value in a
studio will, as usual, change its associated FX preset parameter. If there happens to be an
FXMod also controlling that parameter, the FXMod link will be broken, just as if you reset the
parameter from inside the FX preset.
Using FXMods So You Don't Have to Change Studios
We've mentioned that FXMods are a good way to get around the need to create a new studio
every time you want to make a small change in a studio's parameters. The same studio can be
used for many different purposes if you use FXMods to control it. FXMods can set the gain of
the signals going to the various FXBuses, set panning and output levels of the signals from the
buses, configure the mix going to the Aux bus, and even turn FXBuses on or off, as well as set
processing parameters.
Since any parameter except the ones that reconfigure a studio (see What Can't Be
Controlled on page 15-23) can be under FXMod control, the amount of variation between the
various program- or setup-controlled versions of a single studio can be very great.
Static FXMods
Static FXMods, that is, FXMods that are just going to be used to "set and forget" studio
parameters when a program or studio is called up (as opposed to dynamically controlling
them), are easy to set up. On the FXMOD page, select the bus and parameter you want to
control, set the Adjust value to the parameter value you want, and set Source to OFF. When you
are done, save the program or setup normally. Now whenever you select the program or setup,
the parameters in the FXMods will be immediately reset to the values you've specified.
Room Type and other potentially glitch-producing parameters work much better as static
FXMods than they do under dynamic control. If you need to change a Room Type in a reverb
when you change a program, you can do so with a static FXMod without hearing horrible
glitches, as long as you make sure there is no signal passing through the reverb at the moment of
the program change.
