Real-time Control of KDFX
Setting up FXMods
4-6
Breaking the Links
When FX Mode is in ÒProgramÓ or ÒSetupÓ and you are in the Studio Editor, if you change a
parameter that has been assigned an FXMod, it ÒbreaksÓ the linkÑthe 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
saving it, and go back to the FXMod pages of the Program editor, the link automatically re-
establishes itself.
If you change the FX Preset on an FXBus, the FXMod links to the FX Preset on that bus may or
may not break. If the FX Preset youÕre calling up uses
the same Algorithm as the Preset youÕre
leaving, the links will stay intact. If it uses a different AlgorithmÑeven a similar oneÑthe links
will break. On the other hand, if you are inside an FX Preset, and you change its Algorithm, that
breaks the links. Again, the links will be re-established if you leave the Preset without saving it.
If you have FXMod links to the Aux and Mix parameters on an FXBus, they do not get
interrupted when you change the FX Preset on that bus.
The same rule applies when you are on the KDFX page in a Program or Setup and you change
the Studio. If you have links to the Input and Output pages and the Level parameters on the
FXBus pages, they will be retained, but links to processing parameters will only be retained on
a given FXBus only if the Algorithm inside the FX Preset on that bus isnÕt 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 a parameter under FXMod control happens also to be assigned a Bus Override, it doesnÕt
make a difference to KDFXÑthe FXMod in the Program will control the parameter as if the Bus
Override wasnÕt 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. Should there be an FXMod
which is also assigned to that same parameter,
the FXMod link will be broken , just as if you reset
the parameter from inside the FX Preset.
For example, letÕs say you have a Bus Override on FXBus1 assigned to Wet/Dry for the reverb
FX Preset that is on that bus. You also assign an FXMod from a Program to that same Wet/Dry
parameter on FXBus1. Now if you change the Bus Override, thus changing the Wet/Dry value
of the reverb, the FXMod link to that reverb will be broken, and wonÕt re-establish itself unless
you re-assign it from the Program, or else leave the Program without saving it.
Using FXMods so you donÕt have to change Studios
In the previous chapter, we 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 StudioÕs 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, conÞgure the mix going to the Aux bus, and even turn FXBuses on
or off, as well as set processing parameters within the FX Presets.
Since any parameter except the ones that re-conÞgure a Studio (see ÒWhat CanÕt Be
ControlledÓ, earlier) 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.
