Conference napalm::commusic_v1

    The only patches available from this conference are in SYSEX dump
    format (as far as I know).  There is a list of available software in
    topic 17. 

    If someone is aware of a program that xlates SYSEX to readable values,
    I'll put it in the library.

    In the meantime, there are a few people who have built some MIDI stuff
    for the PRO.  Try DIR/TITL="PRO", "PDP", or "computer" for more leads.

    Hi, Brad
    
    thanks for answering that prompt. I've tried to find something about
    the pro in the conference with no sucess.
    If you (or someone else) could give me more hints you'd help me
    a lot.
    Perhabs I could use the pro to xlate the sysex (I've read a note
    that someone wrote a FORTRAN-prog and tried to copy it but it wasn't
    there).
    As far as I know there are many people who do not use the DX7 no
    longer because there's better stuff available now, but for me and
    the Band I'm with there is nothing better for playing live.
    Could someone tell me, why there is no more support on the DX7 (first
    model -- which is not THAT old) at the dealers????
    And if someone is using midi live he'll be welcome for giving hints.

    Chris - there are SYSEX dumps on:

	DYO780::DISK$USER05:[MIDILIB.PATCHES.DX7.*]

    You'll find associated .LIS files listing the contents of each subdir
    (for example, USENET.DIR has a corresponding USENET.LIS that lists
    banks and patches). 

    And, since I can't find Rataski's DXDUMP program, I'll make available a
    DCL hack I wrote (just to see if I could do it).  It's not fast, and it
    only does a bank at a time (32 or nothing) but it works.  You'll
    find it on:

	DYO780::DISK$USER05:[MIDILIB.TOOLS.HACKS]DXDUMP.COM

    To use it, do:

	$ @DXDUMP sysex_file				or,
	$ @DXDUMP/OUT=list_file sysex_file

    Good luck.  And no comments about my crappy "code".  8-}

    Thanks Brad, the Procedure you gave did fine work. I wrote another
    procedure to submit DXDUMP, because you're right in saying that
    it'll take a while.
    But the result is exactly what I needed. Guess you can't wait to
    receive a tape of TRACES.
    
    Chris.

I have a program that reads sysex files (DX7 dumps) and prints the patches to 
the screen or the printer. I modified a program I fould on Compuserve to make 
it a little more intelligent. If you would like a copy tell me where to upload 
it. It's for an IBM-PC.

BTW - I like my DX7. I have the E! upgrade in it and it is fabulous with my 
wind controller and as a master controller for some other things. Sounds good, 
too. Wouldn't trade it.

    I have another question: How does the old DX7 (TX7) do its checksum??
    I have seperated a bunch of banks into individual patches. Now I want
    to recombine those individual patches (in alphabetical order) into new
    banks. I need to know how the DX7 calculates its checksums and on which
    part(s) of the bank (or which part(s) of the sysex message)???
    
    Any info??

    I've no idea how the DX-7 does this, but my DX21 uses the 7 least
    significant digits of the 2's compliment of the sum of all the data
    bytes to figure the check digit for *1* patch, not an entire bank.
    
    The C code is in note 146.
    
    You may find the answer in your manual, mine was there.

    The checksum for an entire bank dump on the DX21 is figured the same
    way as for a single patch, leading me to think it's Yamaha's standard
    method and would probably work on a DX-7 as well...
