Executing an effect without cross-point changes
Key frames normally include cross-point selection information, but if you set
F1 (XPT DSBL) in the RUN MODE menu to "ON", the effect is executed
with the current input signal selection state unchanged.
Setting the execution timing of several channels
To operate according to the reference channel
When executing effects in a number of channels simultaneously, to carry out
the operations of all channels according to the reference channel settings
(STOP NEXT KF, NEXT KF, PREV KF, etc.), set F3 (END TIME) to
"SAME".
Additionally, if the completion times on the channels are different, in this
mode the effects on all channels will continue to be executed until the latest
time. When the REV button is lit, execution starts from the channel with the
latest completion time.
Operating the channels independently
When executing effects in a number of channels simultaneously, to carry out
the operations of all channels independently of the reference channel, set F3
(END TIME) to "INDPND".
Additionally, if the completion times on the channels are different, in this
mode the effects on all channels will continue to be executed until their
respective times. When the REV button is lit, the channels start execution
simultaneously, and finish in the order of increasing time.
Notes
• In INDPND mode, even when completion times in different channels are
different, moving the fader lever through its complete travel causes a
simultaneous completion of execution, and the effect is thus different from
that of using the RUN button.
• It is not possible to make switcher subregisters operate independently of
each other even when F3 is set to "INDPND".
Disabling the keyframe fader lever
Setting F10 (KF FADER) to "DSBL" disables the keyframe fader lever.
