Owner's Manual Addendum

Controlling the LXP Series of Multi-Effects Processors

Two-way communication is used for more sophisticated applications. For
instance, in order for a sequencer to record

and playback MIDI data from a

single synthesizer, they must be set up for two-way communication. Two
cables are required. One is run from the synthesizer’s MIDI OUT to the
sequencer’s MIDI IN. This sends the MIDI data from the synthesizer to the
sequencer where it is recorded. Another cable is run from the sequencer’s
MIDI OUT to the MIDI IN of synthesizer. This sends the recorded MIDI data
back to the synthesizer, where it is played.

Editor/librarian programs for MIDI effects units are other examples of
applications that require two-way communication to upload parameter
settings from the effects device into the computer, and download them from
the computer back into the effects unit.
