M IDI

10.2 MIDI

This chapter provides information (all implemented MIDI transmission commands) for the experienced software programmer that wants to design new software for the DSP 244. The implementation chart is relevant for the software revision V1.0 or higher.

MIDI data transfer is possible, only when a MIDI channel is activated (OMNI, 1 - 16). See also chapter 9.7, MIDI RX / TX CHANNEL settings.

10.2.1 GENERAL MIDI COMMANDS

Program Change	MIDI-Byte	Description
	0xCn (hex)		n = MIDI Channel 0 - 15
	0xxx xxxx (bin)	1	.. 30 = User Programs U01 .. U30
		31	.. 80 = Factory Presets F01 .. F50
			0 = Recall current program

10.2.2 MIDI SYSTEM EXCLUSIVE IMPLEMENTATION

Identity Request	MIDI-Byte	Description
(recognized)
	F0 (hex)	System Exclusive
	7E	Universal System Exclusive Non-real time header
	0n	n = MIDI Channel 0 - 15 (7F = All Channels)
	06	General Information
	01	Identity Request
	F7	End of SysEx Message

This command tells the DSP 244 to return its ID-number.

The DSP 244 sends this ID-Code as a reply to an Identity Request. Transmitted are the DYNACORD ID-No. 48, the DSP 244 UNIT-ID No. 24, a 3-Byte Unit-Code and the Revision No.
