Patches And Dynamic Midi - Lexicon LXP-5 - REV 1 Owner's Manual

LXP-5 Owner's Manual
Living with controller quirks
Some synthesizers and controllers cannot send the full range of MIDI
program change messages (0-127). With them, you can't access all the
registers in the LXP-5. Others may appear to be able to send only 32, but
actually have a bank mode that does let you send all 128 program change
messages. If in doubt, see the manual for your controller.

Patches and Dynamic MIDI

Some extremely useful effects can be created by controlling the LXP-5's
variable parameters remotely in real time. Almost all of the controllers found
on a MIDI keyboard or foot controller (pitch benders, mod wheels, sliders,
switches, breath controllers, foot pedals and footswitches) can be used to
adjust the LXP-5's parameters. We refer to this real time remote control
capability as Dynamic MIDI .
To use Dynamic MIDI , you patch a MIDI controller to the parameter you
want to control. You may patch a separate controller to each parameter, or
patch a single controller to control up to four parameters at once. Three types
of patches are used in the LXP-5: general purpose patches, an ADJUST
knob patch and global patches.
General Purpose Patches
Four general purpose patches are available in the LXP-5. These patches
use a MIDI controller, a front panel knob or the low frequency oscillator (LFO)
as sources to control one of the LXP-5 parameters, known as patch
destinations . A controller threshold is used along with a positive or negative
scale factor to calculate offset . (Offset = [Source Value - Threshold] x Scale
Factor). The last calculated offset is stored with the patch so that, on recall,
the parameter will have this value until the controller is moved. Four general
purpose patches may be stored with any program by using the front panel
controls or MIDI SysEx.
