    I only discovered this app / forum today..!

    am also very interested in finding or creating a sysex controller for the Lexicon PCM-70

    I have the sysex implementation chart from the manual, but am wondering where to begin to learn the process of using Ctrlr to send (and recieve) the parameter data..

    I’ve made the following notes in order to try to control the Concert Hall Algo initially..

    Setting up a Sysex controller for the Lexicon PCM-70 Concert Hall

    Program type 7 [concert hall]

    Bulk Data Format:

    Byte# Data
    0 Program Type
    1 Stored Parameter Matrix position ROW
    2 Stored Parameter Matrix position COLUMN
    3-16 Name (14 characters last character must be 0
    17-26 MIDI patch sources
    27-36 MIDI patch destinations
    37-46 MIDI scale factors
    47-167 60 2-byte words, different for each program type

    2 byte words are in the following form:

    Byte
    0 dddd dddd Low 8 Bits
    1 0000 00dd High 2bits
