Transition Preview
With the preview output of the M/E bank and PGM/PST 
bank, you can check the effect of a transition in advance.
To perform a transition preview, the [TRANS PVW] 
button must be assigned to a button in the transition control 
block beforehand in the Setup menu (see page 411).
• It is not possible to carry out a transition preview in the 
following cases.
- Transitions in progress
- Multi-program mode
-DSK mode
- Bus fixed mode
• Transition preview operations are not supported using 
the transition control block (simple type).
There are three modes for a transition preview.
Hold mode: Transition preview mode is enabled only 
while the [TRANS PVW] button is pressed.
Lock mode: Pressing the [TRANS PVW] button switches 
between transition preview mode and normal mode 
each time the button is pressed.
One-time mode: Pressing the [TRANS PVW] button 
switches to transition preview mode, and the mode 
returns to normal mode when the transition finishes.
Set the transition preview mode in the following 
combinations in the Setup menu.
For details, see “Setting the Button and Fader Lever 
Operation Mode” (page 431) and “Setting the transition 
preview mode” (page 468).
