which receives all channels) to retrieve this data. It’s a good idea to include the channel assignment in the System Exclusive file name to prevent possible confusion.
To back up:
1.Connect the D4’s MIDI Out to the MIDI In of the other D4 or system exclusive storage device, such as the DataDisk.
2.Select the fifth MIDI page, Sysex Backup. With the Sysex Backup page selected, the Store LED will light.
3.Use the Data wheel to call up one of the four available types of data for backup (figures in parenthesis give the approximate amount of memory required by each type):
Edit Buffer data (500 bytes)
Trigger Setup data (50 bytes)
Program Table data (150 bytes)
System (All) data, which includes Drum Sets, trigger setup, program table, and MIDI assignments (8Kbytes)
4.Press the Store button. The display will say SENDING SYSEX DATA OUT MIDI.. to confirm that data is being sent. The sys ex receiving device should indicate that it is receiving data.
After the transfer is complete, the D4’s LCD reverts to the Sysex Backup page.
Note: The MIDI Thru function is disabled while Sys Ex is being transmitted.
4.6A Save to DataDisk
Here’s an example of how to save D4 MIDI data to the Alesis DataDisk.

2.Insert a formatted disk into the DD. If the disk is not formatted, insert it in the drive and press the DD Format switch. When the DD display says FORMAT DISK?, press DO/YES. When the display says ARE YOU SURE? press DO/YES again.
3.Press the DD Receive button. The display says RECV ONE SYSEX: WAITING FOR DATA.
4.Press the D4 MIDI button (if you are not already in the MIDI function) and select the Sysex Backup page.
5.Select the type of data to be saved (System, Edit Buffer, Trigger Setup, Program Table).
