LXP-5 Owner's Manual
Parameter Definitions
All LXP-5 parameters are 7-bits wide. Unipolar parameter values range from
0 to 127; bipolar parameter values (Patch Scale and Offset) use two’s
complement and range from -64 to +64. The most significant bit (MSB)
always equals zero.
All parameters are accessible by Parameter Change messages. There are
two major parameter classifications: Program parameters and System
parameters.
Program Parameters
Generally, the values of these parameters 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.
Most 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).
The knob mechanism parameters are used to provide an extra degree of
control over the microcode parameters. For instance, six of them are used
to provide coarse/fine control over delay time from Edit mode.
System Parameters
System parameters are not associated with any particular program. These
parameters include Footswitch mode, Memory Write-Protect, global patch
sources, and Preset and User memory location numbers.
