Using the Algorithms
This Chapter will discuss the processing Algorithms found in KDFX: what their parameters
mean, and how to use them. It is designed to be read through so that you can get a general
understanding of the Algorithms.
The descriptions here do not include all of the parameters associated with every Algorithm,
and some Algorithms may not have some of the parameters described here for their category. A
more complete reference, with every Algorithm and the meaning and range of every Parameter,
arranged in the order they appear on the screen, can be found in the
KDFX Algorithm
Reference .
But Þrst, a word about how the KDFX Studios in ROM are organized.
Conventional Studio Structure
Many of the Studios provided in ROM follow an overall organizational plan, which uses
KDFXÕs resources efÞciently and clearly. While by no means are you required to follow this
structure when creating your own Studios, itÕs a good idea to become familiar with it, and see
how KurzweilÕs own engineers have approached the complex issue of Studio organization.
And certainly it can serve as a good starting point when you strike out on your own.
The organization of the ROM Studios follows the following guidelines:
¥
ROM Programs and layers in ROM Setups are assigned to outputs (KDFX-A through
KDFX-D on the
Program:Output or Setup:CH/PRG page) based on the type of effects
processing that would most likely be appropriate for their sound.
¥
All Inputs go to their respective FXBuses (Input A to FXBus 1, Input B to FXBus 2, etc.),
and
only to their respective FXBusesÑthe Lvl parameter for the second FXBus on each
Input page is turned Off.
¥
FXBus 1 contains a relatively simple reverb with a low Size requirement.
¥
FXBus 2 contains an effect which does not increase the ÒlengthÓ of the sound (that is, not
reverb or delay). Possibilities include chorus, ßange, phaser, distortion, shaper, pitcher,
enhancer, EQ, or EQ morpher.
¥
FXBus 3 contains effects that take up lots of time, such as delays, delays with reverb, or
other ÒLeadÓ sounds.
¥
FXBus 4 is dry (since the Þrst three FXBuses have probably used up all the PAUs), and can
provide a ÒbypassÓ path for sounds to go directly to the AuxFX Bus effect.
¥
The AuxFX Bus contains a larger reverb (Size=2 or3), a compressor, or a graphic EQ. It can
be used instead of an FXBus reverb, such as the one on FXBus1. When used this way (set
the Aux Lvl on the FXBus to 0dB or higher), it frees up that FX Bus for use as an Enhancer,
Stereo Image, Flanger, etc.
