2) Use the 

UP

 and 

DOWN

 keys to select between 

enable

 and 

disable

.

If you choose 

disable

, the track referred to by 

the controller’s command signals as “analog 3” 
will be the audio track designated as “analog 3” in 
the 

Track Mapping

 menu above. If you 

choose enable, the DA-98’s timecode track will be 
mapped to the track referred to by the controller’s 
command signals as “analog 3”.

11.1.8 Remote track arming

You may sometimes want to disable the arming of 
tracks from the remote system (either TASCAM 
bus, MIDI or 9-pin). 

Since many video editors, etc. only provide for the 
control of four tracks, this means that you cannot 
control the eight tracks of the DA-98 from the edi-
tor, and so remote track arming should be dis-
abled, allowing you to control the tracks locally.

1) Go to menu group 3, move the cursor to 

Trk

Arm

, and press 

ENTER

:

2) Use the 

UP

 and 

DOWN

 keys to select between 

enable

 and 

disable

.

11.2 Bus protocol

If Bus protocol is selected (see 11.0.1, “Selecting 
the control source (protocol)”), the DA-98 can be 
controlled by controllers such as the TASCAM 
ES-61.

Each DA-98 must be assigned a unique number 
between 1 and 127, as described below.

11.2.1 Assigning a MIDI and Bus ID to the 

DA-98

A MIDI ID is used in a MIDI Machine Control 
setup to identify each unit in the MIDI chain. The 
same number is also used as a Bus identifier.

One (and only one) of up to 127 units can be des-
ignated as the MIDI Timecode Master for the 
whole chain.

This MIDI ID is not the same as a MIDI Channel 
number (even though some units’ manuals may 
refer to it as a “channel number”), and is not con-
nected with the Machine ID (see 9.2, “Machine ID 
and master/slave settings”). To set the MIDI ID:

1) Go to menu group 7, move the cursor to 

MIDI ID

, and press 

ENTER

:

2) Use the 

UP

 and 

DOWN

 keys to select a value 

between 

001

 and 

127

, making sure that this 

ID is unique in your setup.

You can also use the function keys as number keys 
(see 5.2.2, “Using the function keys as number 
keys”) to enter the MIDI ID directly.

You can also select the value 

Receive All

which allows the DA-98 to accept all MMC com-
mands transmitted over the MIDI network (this 
setting has no effect if Bus is selected).

11.3 MIDI Machine Control

As well as control from the 9-pin RS-422 port, the 
DA-98 can also accept commands received at the 

MIDI IN

 port (page 3-1) using the MIDI Machine 

Control protocol.

Set the MIDI ID using the method described 
immediately above.

The MMC commands used by the DA-98 are 
listed in see 15, “Options, specifications and refer-
ence”.

The control source must be set to 

MIDI

 (see 

11.0.1, “Selecting the control source (protocol)”) 
for this to be effective.

The implementation of the MIDI Machine Control 
protocol and the commands which are available 
are described in 15.3, “MMC Bit Map Array”.

11.3.1 MMC commands and the DA-98
