11 – Machine Control/Location—Selecting devices for control82 TASCAM DM-24 Reference ManualTRA This two parameter allows the transport con-trols of the DM-24 to control the transport of theselected device (TRA).Only one device at a time can be selected for trans-port control, as shown by the circled © symbol. If adevice has been selected for transport control, and itis required to control another device, the first deviceselected for external control must be de-selectedfrom transport control before the “new” device isselected for this purpose.If the device is not active when an attempt is made toassign the transport control here, a popup messageappears and the assignment is not made.One feature which is not visible from the transportcontrols is an “eject” function. DTRS units, as wellas most VTRs, can have their media ejected by press-ing and holding the STOP transport key, and pressingthe CLEAR key of the auto-punch section (not thenumber keypad CLR key).Some machines may unthread the tape if the STOPkey is pressed while the transport is stopped.NOTEThe exact way in which the transport controls workwith the external device depends on the capabilities ofthe device. For instance, the notion of “record” is notvery meaningful when applied to the internal timecodegenerator.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 ableto supply you with further information.REC This allows the selection of the REC keys onthe 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 (24tracks).Use the ENTER key to confirm the choice.An appropriate pop-up error message is displayed ifan attempt is made to assign two overlapping groupsof REC controllers. Use the ENTER key to accept thenew assignment, or the cursor keys to dismiss thismessage and return to the previous assignment.NOTEWhen the MASTER indicator is lit (the master layer isselected), the module REC keys have no effect.The ALL SAFE key above the STEREO fader can beused to turn off the track arming for all tracks for allassigned REC keys. While ALL SAFE is active, theREC keys are disabled, until ALL SAFE is turned offagain. The recording status that was active before theALL SAFE was turned on is restored when ALLSAFE is turned off again.Machine Control mapping memoriesSo that commonly-used machine control settings canbe stored and recalled easily, the DM-24 provides 10memories of machine control mappings (numberedfrom 0 through 9).Each of these may contain a device which may becontrolled by the transport control facilities of theDM-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 theexample 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 RECkeys will control the three DTRS units. The DTRSunits will be locked and chasing the VTR. Some-times, though, it will be necessary to control theDTRS units directly (through the first DTRS).Recording functions are still assigned to the DTRSunits.The mappings are automatically assigned when theTRA AUTO DETECT button is “pressed” after the unitshave been added to the list.A pop-up window appears asking if the autodetectprocess should take place (as it will delete all previ-ous mappings).Press ENTER to continue with the autodetection, orany of the cursor keys to cancel the process.When the scan is complete, a pop-up screen appears,showing the detected devices and their assignmentsto the control maps.Any selected devices that may be controlled aredetected and a new map is created for each suchdevice.A message is shown if there are more devices con-nected than can be added to the list (that is, more than10).If there are IDs associated with the devices, these arealso shown.
