  • Page 4: Overview

    • Enter the Lexicon library Overview The Lexicon PCM 80 is a complex device with an involved MIDI System Exclusive implementation. This document describes the Version 1.10 PCM 80 MIDI implementation, and assumes familiarity with the functions and operations of the PCM 80. MIDI Implementation information relevant to PCM 80 algorithm cards, or to Version 1.00 software, is available in separate documents...

  • Page 5: Enabling System Exclusive Messages

    PCM 80 Version 1.10 MIDI Implementation Details Lexicon Data Dumps A dump contains information about some aspect of the PCM 80’s internal state. A dump is transmitted by a PCM 80, eitheron request to another device, or to another PCM 80 (via front panel dump commands or SysEx Automation).

  • Page 6: Sysex Automation

    PCM 80 Version 1.10 MIDI Implementation Details Lexicon SysEx Automation SysEx Automation is intended primarily for facilities using multiple PCM 80s in identical modes of operation. This mode, which is enabled from the PCM 80 front panel, asumes that all units have the same effects in the same locations and the same algorithm cards loaded, and that a single master unit front panel is controlling all slaved units.
