Parameter Definitions - Lexicon LXP-15-II Owner's Manual

Most LXP-15 II parameters fit into 7 data bits to make it easier to transfer data
via MIDI. We've labeled these "Small Parameters". A few parameters, notably
delays, require more than this range. These "Big Parameters" are constructed
of two consecutively numbered small parameters. The lower-numbered pa-
rameter can be accessed as the Fine portion of the big parameter, and always
has a range of 128. The higher-numbered parameter can be used to access the
Coarse portion of the big parameter. The full range of the Fine portion (128 steps)
always equals one step of the Coarse portion. When reference is made to a big
parameter, the number given is that of the Fine portion.
When setting or requesting a big parameter value via SysEx, the value can be
sent either by a big parameter message, or by two small parameter messages.
All parameters are accessible by Parameter Change messages. There are two
major parameter classifications: Program parameters and System parameters.
Generally, program parameter values will change when each new setup is
loaded. Typically, this means that the values of these parameters are stored as
part of a program. Similarly, when a new setup is retrieved, all of its stored
program parameters are retrieved with it.
All program parameters are accessible via the front panel ADJUST knob and
MIDI SysEx. A SysEx change of one of these parameters will overwrite any
existing value set by a previous knob change and vice-versa (a knob change will
overwrite any existing value set by a previous SysEx change).
System parameters are not associated with any particular program. These
parameters are responsible for the overall operation of the LXP-15 II. They
include MIDI Channel, Display Contrast and Brightness, Global Patch mode and
sources.
