EXAMPLE: You have 2 cameras, and you want to use them in a double box Live Set. You enable Live Set for Camera 1, and select Camera 2 on the FX Bus. When you put Camera 1 on-air/Program Bus, only Camera 1's tally is activated, even though Camera 1 AND Camera 2 are both on the air. Red Tally should be sent to both cameras when this happens. This is how it is done on broadcast switchers. When a source is put on air, it should have Red Tally, regardless of the bus where it is selected, because the image still goes through the Program Bus. Instead with VT, only Camera 1 gets Red Tally, and not Camera 2, even though both are on-air.
