Algorithm The LXP-15 contains several
algorithms
. An algorithm is a set
of instructions that tells the LXP-15's microprocessor how to process the
input signal. One algorithm produces pitch/delay, another produces gated
reverb, etc.
Parameter Each algorithm has a set of
parameters
(controls) that uniquely
characterize it. The settings of the parameters can be changed to create
radically different sounds from a single algorithm.
Program Parameter
values are stored/recalled in setups. Some
examples are: delay time, pitch shift, etc.
System Parameter
values are not associated with a particular setup.
System parameters are not stored in registers or presets, nor do their
values change when a new setup is recalled. Examples are: display
contrast and brightness, MIDI Channel number, etc.
Patch A patch is a routing assignment that allows an LXP-15 parameter to
be driven by a source control such as a footpedal, or a synthesizer mod
wheel.
Setup A
setup
is a collection of specific parameter values responsible for
a certain sound (and as many as four general purpose patches). Each
register or preset is a setup, as is the current state of the machine.
Pages
Pages
are groups of parameters (or other quantities) whose names
and/or values are displayed simultaneously.
Register/Preset The LXP-15 contains 256 setups. 128 of these are
presets
which are useful setups permanently initialized at the factory; 128
are
registers
which are available for storing your own setups and effects.
The factory presets cannot be overwritten, but they can be modified and
stored into registers (or copied into registers, then modified). When
shipped, the LXP-15 already has a duplicate of the presets loaded into its
registers.
