delays. These parameters are called “bus overrides,” because they override parameters which
are actually inside the FX preset itself—these parameters can be adjusted from inside the
FX preset, or they can be set from out here, where they are much more convenient. If you change
FX presets, these values change, because their values inside the various FX presets are all
different. There will be more about bus overrides a little later in this chapter.
Allocation
The Allocation parameter determines how many processor allocation units (PAUs) are reserved
for this FXBus. The number of PAUs an FX preset uses is dependent on the algorithm at the core
of the FX preset. Algorithms can use anywhere from 1 to 4 PAUs, depending on their
complexity. As you scroll through the FX presets, the number of PAUs required by each one is
shown on the top line of the display (Size:), along with the number of PAUs that are available
(Free:) for other algorithms.
The 4 insert FXBuses have 4 PAUs to share among them, so if any bus uses more than one PAU,
it means that some buses cannot be assigned an FX preset. This is a very common situation, as
you shall see. The Aux bus has its own set of 3 PAUs, which are completely independent and are
not shared with the insert FXBus PAUs.
You can preassign a PAU value to an FXBus, in which case any FX presets that require more
PAUs than you have given the bus cannot be loaded into the bus. If you try to put an FX preset
into a bus that requires more PAUs than are currently available on that bus, the preset’s name
appears in parentheses—exactly the way a KB3 program appears if you try to select it on a
channel that’s not the KB3 channel.
In most factory studios, the Allocation parameters are set to Auto, in which case PAUs are
assigned dynamically as you assign FX presets to the various buses. As you unassign FX presets
from buses, or assign FX presets with smaller PAU requirements, the PAUs freed up are
automatically reassigned to other buses where they are needed.
A value of Auto for this parameter allocates PAUs to lower-numbered FXBuses first, as needed.

This is the INPUT page. It is showing Input A, as indicated both on the left side and in the upper
right corner—use the Chan/Bank buttons to view the other three inputs. Input A is the first
stereo signal pair coming from the K2600/K2500 Program Editor’s Output section. Depending
on how the K2600/K2500 is set up, this could be a single layer of a single program, or multiple
layers, or multiple programs, or one or more zones from a setup, or the output from one or more
MIDI channels.
