■ THRESHOLD field
4
UPSTROKE/DOWNSTROKE
These specify the level that will be the threshold for outputting a trigger signal. A trigger signal
will be output when the fader exceeds the UPSTROKE level, or when the fader falls below the
DOWNSTROKE level. If FADER TALLY is selected as the fader mode, UPSTROKE and
DOWNSTROKE specify the level range for which a trigger signal will be output. You can use the
multifunction knobs to operate these parameters.
NOTE
• The THRESHOLD values specified by the UPSTROKE/DOWNSTROKE knobs are common to
all GPI OUT ports. However, you can individually choose the channel (fader) for each GPI OUT
port.
• Only the UPSTROKE value will be valid if MODE is set to FADER START, and only the
DOWNSTROKE value will be valid if MODE is set to FADER STOP. If MODE is set to FADER
TALLY, both the UPSTROKE and DOWNSTROKE values will be valid.
■ MODE field
Here you can select the mode of fader operation that will be the trigger for signal output from the
GPI OUT port.
You can choose from the following fader modes.
5
FADER START
A trigger signal 250 msec long will be output when the fader of the selected channel moves
upward through the specified UPSTROKE level (–∞ to +10.0 dB) from a point below it.
6
FADER STOP
A trigger signal 250 msec long will be output when the fader of the selected channel reaches the
specified DOWNSTROKE level (–∞ to +10.0 dB).
7
FADER TALLY
A trigger signal will be output when the fader of the selected channel moves upward through the
specified UPSTROKE level (–∞ to +10.0 dB) from a point below it. This signal will be held until
the fader reaches the specified DOWNSTROKE level (–∞ to +10.0 dB) or until that GPI OUT
port receives a different trigger.
The following illustration shows how the signal that is output from the GPI OUT port will change in
each fader mode when a fader is operated. In this example, UPSTROKE in the THRESHOLD field is
set to –60.00, and DOWNSTROKE is set to –∞. (This illustration shows the case in which
selected as the polarity of the GPI OUT port. If the polarity is
will be reversed.)

NOTE
At the high level, the output signal of the port will be open. If the receiving device requires high
level, take it from the +5V power supply pin. However in this case, the amount of current is limited;
for details, refer to the "Input/output characteristics" section in the separate Owner's Manual.
5.
For each GPI OUT port, specify the channel that will cause the external device to
operate, and the type of operation.

When you have finished making settings, click the "x" symbol located in the upper
right to close the FADER MODE screen.
