TASCAM DA-78HR
10.3MIDI Control Change
It is also possible to send use MIDI Control Change
messages to control the sub-mixer parameters, as
described here:
MIDI channels 1 through 8 control channels 1
through 8 on the master DA-78HR in a DTRS chain.
MIDI channels 9 through 16 can be used to control
channels 1 through 8 on the first slave DA-78HR in a
chain.
10.4MIDI System Exclusive
The following are the System Exclusive formats used
by the DA-78HR:
10.4.1 Identity Reply
Reply to an Identity Request:
10.4.2 TASCAM Exclusive messages
These TASCAM Exclusive messages are developed
for controlling DTRS recorders connected to each
other via the
SYNC IN
connections.
The messages follow the following format:
10.4.3 Track delay
Track delay can be set from –200 through +7200
<cc> = 04
<data> is 5 bytes: <tk><da><db><dc><dd>
<tk> = 0s000ttt
where s= sign bit (1 if negative) and
ttt
is the track number.
<da>, <db>, <dc> and <dd> represent the units, tens,
hundreds and thousands digits respectively of the
delay value.
10.4.4 Crossfade
Can be set from 0 to 90 ms in this way
<cc> = 05
1 data byte, taking a value from 0 through 9 (0
through 90 ms)
10.4.5 Machine offset
Used to set the machine offset of a slave machine
chasing to a master via a
SYNC IN
connection (the
master’s chase cannot be set, of course).
The limits of this parameter are ±02:00:00.00. If a
value over or below these limits are entered, the limit
value will be set.
<cc> = 06
<data> is four bytes: <hh> <mm> <ss> <ff>
<hh> = 0sssuuuu
, where sss=000 means a plus value,
and sss
=01 is a minus value. uuuu is the hours
setting.
