11 – Machine Control/Location—Selecting devices for control

TASCAM DM-24 Reference Manual
TRA This two parameter allows the transport con-
trols of the DM-24 to control the transport of the
selected device (
TRA ).
Only one device at a time can be selected for trans-
port control, as shown by the circled
© symbol. If a
device has been selected for transport control, and it
is required to control another device, the first device
selected for external control must be de-selected
from transport control before the “new” device is
selected for this purpose.
If the device is not active when an attempt is made to
assign the transport control here, a popup message
appears and the assignment is not made.
One feature which is not visible from the transport
controls is an “eject” function. DTRS units, as well
as most VTRs, can have their media ejected by press-
ing and holding the
STOP transport key, and pressing
the CLEAR key of the auto-punch section (not the
number keypad CLR key).
Some machines may unthread the tape if the STOP
key is pressed while the transport is stopped.
NOTE
The exact way in which the transport controls work
with the external device depends on the capabilities of
the device. For instance, the notion of “record” is not
very meaningful when applied to the internal timecode
generator.
If you require further information on the control fea-
tures of a specific device that are not detailed here,
please contact your TASCAM dealer, who should be able
to supply you with further information.
REC This allows the selection of the REC keys on
the DM-24 which arm the tracks on the remote exter-
nal device.
Use the dial to choose between 1-8 , 9-16 , 17-24 , 25-32
(8 tracks), 1-16 , 17-32 (16 tracks), 1-24 and 9-32 (24
tracks).
Use the ENTER key to confirm the choice.
An appropriate pop-up error message is displayed if
an attempt is made to assign two overlapping groups
of
REC controllers. Use the ENTER key to accept the
new assignment, or the cursor keys to dismiss this
message and return to the previous assignment.
NOTE
When the MASTER indicator is lit (the master layer is
selected), the module REC keys have no effect.
The ALL SAFE key above the STEREO fader can be
used to turn off the track arming for all tracks for all
assigned
REC keys. While ALL SAFE is active, the
REC keys are disabled, until ALL SAFE is turned off
again. The recording status that was active before the
ALL SAFE was turned on is restored when ALL
SAFE is turned off again.
Machine Control mapping memories
So that commonly-used machine control settings can
be stored and recalled easily, the DM-24 provides 10
memories of machine control mappings (numbered
from 0 through 9).
Each of these may contain a device which may be
controlled by the transport control facilities of the
DM-24.
Each of these memories includes: the CHASE setting,
the SCR setting and the TRA setting.
An an example of the practical use of this, take the
example of three DTRS units connected to a VTR,
chasing to timecode supplied by the VTR. Usually,
the transport keys will control the VTR, and the
REC
keys will control the three DTRS units. The DTRS
units will be locked and chasing the VTR. Some-
times, though, it will be necessary to control the
DTRS units directly (through the first DTRS).
Recording functions are still assigned to the DTRS
units.
The mappings are automatically assigned when the
TRA AUTO DETECT button is “pressed” after the units
have been added to the list.
A pop-up window appears asking if the autodetect
process should take place (as it will delete all previ-
ous mappings).
Press ENTER to continue with the autodetection, or
any of the cursor keys to cancel the process.
When the scan is complete, a pop-up screen appears,
showing the detected devices and their assignments
to the control maps.
Any selected devices that may be controlled are
detected and a new map is created for each such
device.
A message is shown if there are more devices con-
nected than can be added to the list (that is, more than
10).
If there are IDs associated with the devices, these are
also shown.
