Understanding Lookahead Preview
bñ~ãéäÉ=OW==hbv=N=iççâ~ÜÉ~Ç
Use the following steps to learn how the KEY 1 button affects lookahead preview.
1. Press SEL to switch the key bus to KEY 1.
2. Select GFX on the key bus.
3. In the Next Transition Group, press KEY 1. This action arms the KEY 1 layer to
transition.
Figure 7-7. M/E Bank: KEY 1 lookahead
Please note:
~ With KEY 1 selected and BG turned off, KEY 1 will transition over the
current BG source. The PST bus will not transition.
~ The source selected on PST does not appear on PVW — because it’s
not part of the next transition.
~ The lookahead PVW output shows the KEY 1 source keyed over BG.
This is the perfect time to clip and adjust the key.
4. Press CUT or AUTO TRAN to cut, mix or wipe KEY 1 over the BG bus.
