MIDI DATA FORMAT
Transmitting and receiving MIDI messages enables two systems to link together.
For example, if a hall contains two systems, and one of them is connected to the control panel, operating the control panel
can cause the second system to operate in sync with the first system. To do so, connect the MIDI OUT of the first system to
the MIDI IN of the second system.
When the MIDI IN connector receives Program Change messages that contain Program numbers, Pattern memories that
correspond to the Program numbers will be recalled. See the table below for more detail. When a Pattern memory is recalled,
AA ON/OFF are automatically set
to ON, but no Control Change messages will be transmitted.
Program Change #
0x00 to 0x05
0x06 to 0x3F
0x40 to 0x45
0x46 to 0x7F
When the MIDI IN connector receives Control Change messages, the corresponding control parameters will change as
shown in the table below. However, in Surround mode, no Control Change messages will be transmitted or received.
Parameters
Control Change #
AA ON/OFF
0x01
LIVENESS
0x02
MIDI messages are transmitted and received in accordance with the MIDI parameter settings in SETUP memory, as shown
in the table below.
When ECHO is ON, the received Program Change and Control Change messages will be transmitted as they are without any
changes. In this case, the messages will be transmitted on the channel that received the messages, not on the channel specified
by the RX Channel parameter.
Parameters
RX CHANNEL Specifies a MIDI channel that receives MIDI messages.
TX CHANNEL
Specifies a MIDI channel that transmits MIDI messages.
OMNI
Specifies whether OMNI is ON or OFF.
ECHO
Specifies whether ECHO is ON or OFF.
