10 – External control–Bus protocol72 TASCAM DA-98HRmenu above. If you choose enable, theDA-98HR’s timecode track will be mapped tothe track referred to by the controller’s com-mand signals as “analog 3”.10.3.8 Remote track armingYou may sometimes want to disable the arming oftracks from the remote system (either TASCAM bus,MIDI or 9-pin).Since many video editors, etc. only provide for thecontrol of four tracks, this means that you cannotcontrol the eight tracks of the DA-98HR from theeditor, 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 TrkArm, and press ENTER:2 Use the § and ¶ keys to select betweenenable and disable.10.4 Bus protocolIf Bus protocol is selected (See “Selecting the controlsource (protocol)” on page 69.), the DA-98HR can becontrolled by controllers such as the TASCAM ES-61.Each DA-98HR must be assigned a unique numberbetween 1 and 127, as described below.10.4.1 Assigning a MIDI and Bus ID tothe DA-98HRA MIDI ID is used in a MIDI Machine Control setupto identify each unit in the MIDI chain. The samenumber is also used as a Bus identifier.This MIDI ID is not the same as a MIDI Channelnumber (even though some units’ manuals may referto it as a “channel number”), and is not connectedwith the Machine ID (8.2.2, “Setting machine ID”).To set the MIDI ID:1 Go to menu group 7, move the cursor toMIDI ID, and press ENTER:2 Use the § and ¶ keys to select a valuebetween 001 and 127, making sure thatthis ID is unique in your setup.You can also use the function keys as numberkeys (4.4, “Using the function keys as numberkeys”) to enter the MIDI ID directly.You can also select the value ReceiveAll, which allows the DA-98HR to accept allMMC commands transmitted over the MIDInetwork (this setting has no effect if Bus isselected).10.5 MIDI Machine ControlAs well as control from the 9-pin RS-422 port, theDA-98HR can also accept commands received at theMIDI IN port q using the MIDI Machine Controlprotocol.The control source must be set to MIDI (10.1,“Selecting the control source (protocol)”) for this tobe effective.Set the MIDI ID using the method described in10.4.1, “Assigning a MIDI and Bus ID to the DA-98HR”.The MMC commands used by the DA-98HR arelisted in 13.3, “MMC Bit Map Array” as is the imple-mentation of the MIDI Machine Control protocol andthe commands which are available.10.5.1 MMC and the DA-98HRAn example of a MIDI sequencer being used to con-trol a DA-98HR (using the auto-punch of thesequencer to punch in and out on the DA-98HRtracks) is given below.
