12 - MIDI-Updating the system software At the end of the dump, the popup display shows Done! and then disappears from the screen. Bulk transfer of data to the DM-24 When the appropriate set of data to be dumped to the MIDI device has been selected, move the cursor to the on-screen BULK LOAD button, and press ENTER. A popup message appears, saying that the DM-24 is now ready to receive the selected data. At this point, a cursor key can be pressed to cancel the operation. At this point, it is a good idea to check that important data which is needed and stored on the DM-24 will not be overwritten by the incoming data. The bulk dump from the remote device should then be started. The receiving DM-24 shows that the start command has been received and when the data transfer is finished, this is also shown on the DM-24 screen. NOTE It is important that the data transfer from a remote device to the DM-24 is not interrupted while it is in progress. If only part of the data is transferred, there is a risk that the library contents, etc. will be corrupted and become unusable. Updating the system software This is a special case of bulk data transfer. Periodically, TASCAM makes upgrades to the DM-24 available through your TASCAM dealer. Consult your dealer, or the TASCAM Web site, for details of these upgrades. The software is provided in the form of a standard MIDI file which must be dumped if it was a song being played from a MIDI sequencer to the DM-24. To update the system software: 1 Turn off all audio devices connected to the DM-24. As the DM-24 resets itself after the software has been updated, this may cause unwanted "thumps", etc. in the audio chain. 2 Connect the MIDI IN of the DM-24 to the OUT of the remote device. 3 On the BULK screen, move the cursor to the PROGRAM VERSION UPDATE [READY] button and press ENTER. A popup message appears. The update procedure can be cancelled at this stage by pressing a cursor key. 4 Start the "playback" from the remote device. The screen shows that a MIDI file dump is taking place and what data is currently being transferred. It provides an indication of the transfer process by blinking. WARNING It is MOST IMPORTANT that you do not turn off the power or otherwise interrupt the transfer of data while a system update is taking place. If the transfer in interrupted, it is almost certain that the DM-24 will be unusable. The DM-24 resets itself when the data has been transferred successfully. After the reset, the other audio devices can be turned on again. Control Change messages to and from the DM-24 As well as being able to send Control Change messages (as described in "MIDI controllers" on page 93), the DM-24 is also able to send and accept Control Change messages to and from a MIDI device using the audio faders, pan settings and MUTE keys of the channels, and the faders and MUTE keys of the master channels. Although the Control Change messages received do not provide full remote control of the DM-24, this does allow for some useful functions. For example, a sequencer can be used to mute and un-mute channels precisely in sync with the musical timing of a piece, rather than by timecode values. The Control Change messages transmitted in this way can also be used to make settings on remote MIDI devices in time with fader movements, etc. 96 TASCAM DM-24 Reference Manual
