TASCAM DA-78HR
10 - MIDI control
10.1MMC enable and disable
The DA-7 8HR can b e control l ed usin g M IDI
Machine Control Commands (MMC). To enable and
disable the DA-78HR’s response to these commands:
1Press the SHIFT key so tha t th e SHIFT indicator
is flashing, and then press the MENU key until
the displa y sh ows MIDI-- (MIDI-- ).
2Press the
SUB MENU key until the displa y
shows
MIDI on or MIDI OFF (MIDI ON or
MIDI OF F
).
3Use the ▲ and ▼ keys to make the appropriate
setting.
NOTE
Turning this p arameter on and o ff will also e nable and
disable respectively the transmission of MIDI
timecode (MTC).

10.1.1Assigning a MIDI I D t o the DA-

78HR

A MIDI ID is used in a MIDI M achine Control setup
to identify each unit in the MIDI chain.
One (and only one) of up to 127 units can be desig-
nated as the MIDI Timecode Master for the whole
chain.
This MIDI ID is not the same as a MIDI Channel
numbe r (even thou gh some u ni ts’ man ua ls may ref er
to it as a “channel number”), and is not connected
with the Machine ID (8.2.2, “Setting machine ID”).
To set the MIDI ID:
1Press the SHIFT key so tha t th e SHIFT indicator
is flashing, and then press the MENU key until
the displa y sh ows MIDI-- (MIDI-- ).
2Press the
SUB MENU key until the displa y
showsID (ID), followed by the current ID
number.
3Use the ▲ and ▼ keys to change the ID to a
value between
1 and 127, making sure that
this is un ique in your setup.
You can also select the default value of ALL
(ALL), which allows the DA-78HR to accept all
MMC commands transmitted over the MIDI
network.
Set the MIDI ID using the method described immedi-
ately above.
The MMC commands used by the DA-78HR are
listed in this section (10.2, “MMC Bit Map Array”).

10.1.2MMC commands an d the DA-7 8HR

An example of a MIDI sequencer being used to con-
trol a D A- 78HR (us ing the au to-pun ch of the
sequ encer t o punc h in a nd out on t he DA-78 HR
tracks) is given below. Note that the sequencing soft-
ware must be able to transmit MMC commands and
also to sync to MTC for this to be effective:
The sequencer is set up to transmit MMC commands,
and is set so that it synchronizes to SMPTE/MTC.
When a “transport” command is given from the
sequencer, the appropriate MMC command is trans-
mitted to the DA-78HR. When the DA-78HR has
located and starts playback (or recording), the MTC
is transmitted back to the sequencer, which locks in
and starts at the correct point.
In this wa y, though the DA-78HR is th e timecode
master, the sequencer is the transport master.
The arrangement shown here uses 2 inputs to the
sequencer. The same effect could be achieved with
the intelligent use of filtering mechanisms.
