1. Get a GM disk that is 01-formatted
1a: Disk XPD-15 from Korg
($15 plus shipping and handling as of Summer 1999).
1b: GM set-ups may also be found on some 01 sites, likt http://www.vienxu.com/korg0.
(If the XPD-15 is no longer available from Korg, check for a file called
"KORG_XPD-15_GM.syx" at the vienxu site. There may be another file called
http://www.vienxu.com/korg0/files/o1gsmi.zip.)
1c: You may find a GM setup file that has the extension ".01w" . You
will need DiskImage to write this file
to a disk formatted on the 01.
2. Insert the GM disk and Load All Data from it. (DISK Mode, Page 0)
3. Verify the transfer by checking that Prog names have changed (Piano-ish Progs for A00-A09).
1. Get a GM setup as a System Exclusive (*.syx or *.sys) file in your
computer.
1a: Check http://www.vienxu.com/korg0
(look for a file called KORG_XPD-15_GM.syx)
2. Send the *.syx file to your 01 over MIDI using any of several
programs (like Cubase or Cakewalk).
This should include all 128 GM Progs and a GM Drum Kit. The Drum Kit
should appear at Prog B28.
3. Verify the transfer by checking that Prog names have changed (Piano-ish Progs for A00-A09).
If you want to play GM sequences, you'll have to "EDIT PROG" Banks A and B to create Programs that are as close to the the GM spec as possible. Use the worksheet to get you started in selecting 01 Progs to assign to your GM Bank. You'll have to edit both Banks because there are 128 GM Programs but only 100 01/W Progs per Bank.
Your GM Banks can not be completely accurate because some GM Programs require Sounds that don't come built into the 01. (Examples include Tango Accordion and Telephone Ring.) These GM Instruments will have to be assigned 01 Multi-Sound(s) that are as close as you can get. You can modify the Sounds once they're in an 01 Program to try and make it closer.
Korg did this for you, and sells it on a floppy disk, XPD-15. Click here to see how Korg assigned Multi-Sounds to create a GM-compatible system.
GM and Drums
But you are not done yet. What about drums? The GM spec also defines
a Drum Kit. This assigns specific drums and percussive instruments to specific
keys on the keyboard. The 01 has four Drum Kits A1, A2, B1, and B2. None
of them match the GM spec. (although B1/Prog 29 overlaps some at the low
end of the keyboard). That means you also have to edit an 01/W Drum Kit
to be like the GM spec. (For details on building a GM Drum Kit, see the
Percussion Manual.)
The tables on this page are only a starting point for those who want to create their own GM setup. You will likely find that the ROM Progs can't be forced into all the GM slots. That will lead you to editing your own Programs to match what you think the GM instrument should sound like. This can be a long and difficult process. Unless you really want to learn about editing Programs, you are better off acquiring the Progs and Kits rather than creating them.
Once you have defined (and saved!) your Banks and Kit, you will be able
to load GM sequences and play them on your 01.
For example, if your sequence has only an electric piano, vibraphone, and electric bass, then conversion is simply replacing the 01 Prog number with the corresponding GM Prog number.
If your 01 sequence uses a Drum Kit, the job just got much harder. Now you need another table showing every Drum Sound used and which key each Sound is on (Crash Cymbal on C4, etc.). Next you find which GM key has the same, or nearest, Sound (Crash Cymbal 2 on A3) (see pages 38-39 in the Percussion Manual). Then you have to go all through your sequence, changing every 01 key to the corresponding GM key. This is can be a simple, though tedious, process on a computer-based sequencer by using the Transpose command. You also must change the 01 Drum Prog number to match the GM Program number.
The real problem is when you use an 01 Prog/Patch that has no corresponding GM Program/Patch. The 01 Sounds are what make it unique, and there are probably dozens of 01 Progs that are very different from any of the GM Programs. It may be impossible to make a good conversion in this case.
