mode enabling to receive this message the data will be received and the whole preset and setup memory
will be overwritten.
MIDI output (MIDI OUT)
Every of 100 presets can send one Control Change and three Program Change commands. For Control
Change command the controller’s number is common for all the presets. Commands are sent each time
after selecting the preset. Successively are sent Program Change 3, Program Change 2, Program Change
1 and Control Change commands.
System Exclusive dump memory message specification
Controller attend one SysEx type message containing presets and setup memory data (memory dump). It
enables to save memory backups and editing presets and setup on the computer. It is possible to copy the
memory from one to another MGC. Sending out the memory contain can be recalled manually in bdp
function (in controller’s SETUP) or remotely by MIDI request message.
Memory contain message specification:
1) First byte 0xF0 - SysEx Start
2) Three bytes G LAB ID ( 0x00 0x20 0x71)
3) SysEx message channel (14h)
4) One byte device ID MGC-6 1.xx (01h)
5) Message statute byte (00h – data to store)
6) 101 frames with memory contain
MIDI specification is expected to send data with cleared eighth bite. Because of that the data is packed in
eight or three data bytes in given way: seven bytes with MSB=0 + eighth with MSBs or two bytes + third as
on the scheme below.
Memory frame containing 16 bytes is sent as a frame with 8+8+3 MIDI data bytes.
First frame contains the general information about the controller and its setup in following order:
a) 3 data signature bytes (03h , 05h , 09h)
b) 1 reserved data byte
c) 1 data byte with the input channel number (range 1-16)
d) 1 data byte with the output channel number for the Program Change 1 (range 1-16)
