1.1

ESQ-M System Exclusive Header

All ESQ-M System Exclusive messages start with the following header. The receiving ESQ-M will only

recognize system exclusive messages if the MIDI channel number in the message is the same as the MIDI base

channel selected on its MIDI page and its MIDI enable parameter is set to recognize system exclusive messages (i.e

the display should show ENABL=KCPSYS).

1.2 Program Dumps

To be able to receive this data, the ESQ-M must be in program select mode (i.e. the program page must be

displayed) and the MIDI enable parameter on the MIDI page must be set to receive system exclusive messages.

1.2.1 Single Program Dump

This transmits the program currently selected on the current Track. Refer to Table 1 for details on the structure of the

program.
