What is KDFX
KDFX Terms
1-2
Alternatively, in a live performance setting, you can use the KDFX in Setup mode as an entire
orchestra, with different instruments layered on top of each other and mapped to different
parts of the keyboard, all with their own signal processing; and that signal processing can
change completely in an instant when you call up a new Setup.
These are just two of the huge variety of scenarios possible with KDFX. The structure of KDFX
is so ßexible that you should never run out of ideas for how it can be used.
KDFX Terms
Before starting to work with KDFX, it would be good to go over some important terminology
that you will be confronting. Understanding the words will help you get the concepts quickly.
Read this chapter Þrst, and refer to it later if something isnÕt clear.
Studio
A Studio is the entire KDFX environment, consisting of Inputs , FX Bus es, an Aux FX Bus , FX
Presets , Parameter settings, Override s, and Outputs . One Studio is current at a time in KDFX.
Studios are objects, like K2500 programs, and have a number. They can be linked to Programs
or Setups using the
FXMode setting . KDFX comes with a large number of useful Studios, and
users can modify them or create new ones and store them in RAM.
FX Bus (also called ÒInsert FX BusÓ)
A signal path with some kind of processing Ña delay, reverb, ßanger, etc.Ñon it. It has stereo
inputs and outputs, and contains an
FX Preset which determines the kind of processing that
will be applied. A Studio has four insert FX Buses, each with its own FX Preset, as well as a Þfth
FX Bus, known as the Aux FX Bus .
Aux FX Bus (or just ÒAux BusÓ)
A separate FX Bus from the Insert FX Bus es, which is placed in the signal path after the output
of the Insert FX Buses, so that it can act as a ÒglobalÓ processor.
Mix Bus
The various outputs of a Studio can appear individually at the K2500Õs physical outputs, or two
or more of them can be combined before they get to the physical outputs. The Mix Bus is where
this combining takes place.
FX Preset
An FX Preset determines the type of signal processing that is present on an Insert FX Bus or the
Aux FX Bus . FX Presets consist of an Algorithm , plus the settings of the Parameters associated
with that Algorithm. More than one FX Preset can use the same Algorithm. KDFX comes with a
large number of FX Presets, and users can modify them or create new ones and store them in
RAM. Algorithms, however, are stored in ROM and are not changeable by the user. Each FX
Bus and the Aux FX Bus gets its own FX Preset, so up to Þve FX Presets can be active in a studio
at a time.
