    Multi-Effects Processors One of the most powerful features of the MRC is its ability to be used as a dedicated controller for Lexicon’s LXP-1, LXP-5 and LXP-15 multi-effects processors. For maximum flexibility with your setup, the MRC can control LXP devices using either one-way or two-way MIDI communication. This section presents the general issues of MRC/LXP control and communica- tion.

  • Page 8: One-Way And Two-Way Communications

    Lexicon MRC V4.0/ MIDI Remote Controller The MRC has several advantages as a dedicated remote controller for Lexicon’s LXP-1, LXP-5, and LXP-15 multi-effects processors. Here are some of the possibilities: • Simultaneous editing and display of as many as four parameters •...
  • Page 9 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.
  • Page 10 Lexicon MRC V4.0/ MIDI Remote Controller It is important to note that two-way communication creates a closed-loop between the two MIDI devices. Unlike a one-way configuration, it is not a simple matter to connect additional devices to a two-way configuration. This is because MIDI outputs cannot be combined on a single cable without a MIDI merger .
