This process will take approximately 45 minutes. You will need a MIDI interface with a MIDI cable coming
from the interface’s MIDI output to the DM-24’s MIDI input. You can use printer, modem, or USB ports.
Mac OS requirements
– Use an Apple Macintosh computer running Mac
OS 8.6 or higher (OS X is not supported).
– The ONLY Mac application TASCAM supports for upgrading the DM-24 via MIDI is MIDIGraphy
version 1.4.3. This application is shareware and can
be downloaded from the TONTATA website.

1. Once you’ve downloaded MIDIGraphy, launch the application. The first thing it will ask you for is your
MIDI interface information. If you use OMS, check the “Use OMS” box and the ports from your OMS
setup will be available in the IN and OUT pull down menus. You will need to download OMS and use it if
you have a MIDI interface that connects via USB.

If your MIDI interface is connected to your PRINTER or MODEM port, choose that port. Once you have
made these settings, click OK.
2. On the DM-24 press SHIFT+OPTIONS
3. Press the soft key below where you see PREFERENCES on the LCD.
4. Use the cursor keys to point to VERSION INFO. You will see a list of different files. Make note of
the current version shown.
5. On the DM-24 press SHIFT+MIDI\/MC then press the soft key below where you see BULK on the
LCD.
6. Use the cursor keys to move the pointer to PROGRAM VERSION UPDATE-READY and press
ENTER.
7. You should see a screen similar to this one. The DM-24 is now waiting to see the incoming MIDI file.
8. With MIDIGraphy open, go to FILE-OPEN. Locate your DM UPDATES folder on the desktop and
open the FLASH file.
A. If MIDIGraphy does not see the MIDI files:
Go to APPLE MENU-CONTROL PANNELS-FILE EXCHANGE
Choose PC EXCHANGE-ADD.
EXTENSION=MID
FILE TYPE=MIDI
Choose MIDIGraphy under MAP TO:
Click ADD.
Now MIDI files can be opened in MIDIGraphy.
9. Now use your mouse to press PLAY in MIDIGraphy
10. The DM-24 MIDI FILE DUMP screen should now show you the name of the file it is receiving and the
packet column should show data movement.
11. When the file transfer is complete, the DM-24 screen will show “SOFTWARE DATA RECEIVE
COMPLETE! DO YOU EXECUTE ROM WRITE? PRESS ENTER TO CONFIRM, OR A CURSOR
KEY TO CANCEL.” Press ENTER on the DM-24. The DM-24 will think for a moment and then
reboot back to the BULK screen again.
12. Now repeat these steps to load the next six files. These files must be loaded in the following order or
damage will be done to your DM-24’s EPROMs and the DM-24 will be unusable:
2. remote.mid (Remote Program Data)
3. main.mid (Main CPU Program Data)
4. preset.mid (Preset Library Data) *
5. diag.mid (Diagnostics Program Data) *
6. start.mid (Main CPU StartUp Program Data) *
7. panel.mid (Panel CPU Program Data)
13. Once these files have been loaded, press SHIFT+OPTION on the DM-24.
14. Press the soft key below where you see PREFERENCES on the LCD.
15. Use the cursor keys to point to VERSION INFO. You will see a list of different files. All of them
should be labeled with the upgraded version you just loaded.
16. Once finished, you will need to initialize your DM-24. Please see the end of this document for that
