MIDI data format
1. Functions
1.1 MIDI-SETUP
There are two types of serial connector: the MIDI connec-
tors and the TO HOST. They have the same functionality,
and you can select which type to use as appropriate for the
connection destination. Both types use the MIDI format for
communication.
In the case of the TO HOST connector, the transmission
method must be selected appropriate for the other device.
The available methods are listed below.
Regardless of which method is selected, MTC is transmitted
from the dedicated MTC OUT connector.
You can select either THRU or OUT as the function of the
MIDI THRU/OUT connector. If THRU is selected, messages
received at the MIDI IN connector will be retransmitted
without change from the MIDI OUT/THRU connector.

1.2 SCENE CHANGE
When a program change message is received, a scene will
be recalled as specified by the [MIDI Program Change
Assign Table].
Program change messages are transmitted with the program
number specified by the [MIDI Program Change Assign
Table]. If multiple program numbers are assigned to that
memory number, the lowest-numbered program change
will be transmitted.
1.3 MMC CONTROL
Basic recorder operations such as stop/play/rec/locate can
be controlled.
If you select MMC MASTER from the MIDI SETUP menu,
MMC commands will be transmitted according to opera-
tions of the transport. If you select MMC SLAVE, the internal
recorder will operate according to the MMC commands
that are received.
1.4 EFFECT CONTROL
Depending on the effect type, note on/off messages can be
received for control.
These settings are made by the parameters of the corre-
sponding effect.
1.5 MIDI CLOCK transmission
If you select MIDI CLOCK transmission from the MIDI
SETUP menu, MIDI clock messages will be transmitted dur-
ing playback and recording.
When the AW4416 is in MIDI clock transmission mode,
Start/Stop/Continue commands will be transmitted by the
corresponding operations, and MIDI Clock and Song Posi-
tion Pointer messages will be transmitted according to the
MIDI Tempo Map.
1.6 MTC master
If you select MTC transmission from the MIDI SETUP menu,
MTC will be transmitted during playback and recording.
1.7 MTC slave synchronization
If you select SLAVE operation from the MIDI SETUP menu,
the AW4416’s internal recorder will operate in synchroniza-
tion with the MTC messages received from the MIDI IN or
TO HOST connector.
2. Internal settings and operations
2.1 MIDI-SETUP
2.1.1 MIDI Channel
2.1.1.1 Transmit channel
Select the MIDI channel used for transmission.
However, transmissions in response to requests are trans-
mitted on the Receive Channel in order to specify the trans-
mitting device.
2.1.1.2 Receive channel
Specify the MIDI channel used for reception. In general,
MIDI messages are received only if the MIDI channel
matches, but this is not the case if OMNI is turned on.
2.1.2 ON/OFF
2.1.2.1 Program change
Reception and transmission can be enabled or disabled. If
OMNI is turned on, program changes will be received
regardless of their MIDI channel. If ECHO is on, they will
be echoed regardless of the channel.
2.1.2.2 Control change
If ECHO is on, these messages will be echoed regardless of
the channel.
2.1.3 MMC Device ID
Specify the ID number used when transmitting and receiv-
ing MMC commands.
2.1.4 PORT
Select whether serial communication will use the MIDI IN/
OUT connectors or the TO HOST connector.
(MTC is always transmitted from the MTC OUT connector.)
If the TO HOST connector is selected, you must also select
one of three settings as appropriate for the other device.
2.1.5 THRU
You can select whether the MIDI OUT/THRU connector
will function as OUT or THRU.
If THRU is selected, messages received at the MIDI IN con-
nector will be retransmitted without change from the MIDI
OUT/THRU connector.
If MIDI THRU is selected, the connector will function as
THRU regardless of the PORT setting. In order to function
as MIDI OUT, the PORT setting must be set to MIDI IN/
OUT.
2.2 MIDI program change assign table
The correspondence between program change numbers
and scene numbers can be set freely.
This conversion is applied to both transmission and recep-
tion.
