MIDI/GPI Using FADER START
■ OUTPUT DESTINATION field
GPI OUT1 – GPI OUT8 buttons
Select the GPI OUT port for which you want to make settings.
Indicates the selected fader. Use the [SEL] keys on the panel to select a fader.
■ THRESHOLD field
These knobs specify the level that will be the threshold at which to output 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.
Alternatively, you can use the [TOUCH AND TURN] knob.
• 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
• 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.
Operating the fader of the selected channel will not cause a signal to be output.
A trigger signal of 250 msec duration will be output if the fader of the selected channel is raised
from below the specified UPSTROKE level (between −138.0 dB and 10.0 dB) to beyond that
A trigger signal of 250 msec duration will be output when the fader of the selected channel
reaches the specified DOWNSTROKE level (between −∞ dB and 9.95 dB).
A trigger signal will be output if the fader of the selected channel is raised from below the
specified UPSTROKE level (between −138.0 dB and 10.0 dB) to beyond that level. This signal
will be held until the fader reaches the specified DOWNSTROKE level (between −∞ and
9.95 dB), or until that GPI OUT port receives a different trigger.
The following illustration shows how the output signal from the GPI OUT port will change
when a fader is operated in each fader mode. In this example, the THRESHOLD field is set to
−60.00 for UPSTROKE, and to −∞ for DOWNSTROKE. (In this illustration,
selected as the POLARITY of the GPI OUT port. If
output signal polarity will be reversed.)
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, there is a limit on the amount
of current that can be provided. For details, refer to the "Control input/output specifications"
section in the data list.
SET BY SEL button
If this button is on, you will be able to add a channel by using the corresponding [SEL] key.
For each GPI OUT port, specify the channel that will cause the external device to
operate, and also specify the type of operation.
