7 ALL STOP button
Touch this button to issue the stop command to all of
the machine control ports.
8 OPEN LOOP button
When MIDI is selected by the Port select button 3,
this button is automatically set to OFF (the button
becomes deactivated) and MIDI must be controlled
using a closed loop (i.e. 2 MIDI cables).
When the return signal is not sent back from the
machine after 2 seconds have elapsed, the unit decides
that it is not possible to exercise control with the
closed loop. In this case, after the dialog is displayed,
the unit changes to open loop control and this button
becomes activated.
Also, you can switch between closed loop control and
open loop control manually.
Note
In OPEN LOOP control, the tape time and the
transport status of the machine can not be displayed.
Also, the transport status may differ from the actual
machine transport.
Open loop control and closed loop control
The open loop control is the one-way control mode
where the command is sent to the machine, but the
return signal is not received from the machine. In the
closed loop mode, the return signal is also received
from the machine. Thus, 2 MIDI cables (one for the
send command and the other is for the return signal)
are required in the closed loop control.
9 LOCATE button
Touch this button to issue the locate command to the
machine at the locate time displayed on the LOCATE
TIME display window.
Notes
• There may be machines that cannot locate even if the
locate command is received.
• The LOCATE button is not effective in the open
loop control.
0 Transport control buttons
Touch the corresponding button to issue the FF, REW,
PLAY, STOP or REC command to the connected
machine.
To set the machine to record mode, touch the REC
button first to make it active, then touch the PLAY
button. Or touch the REC button while playing.
