Where Value 0 = off, 1 = program, 2 = preview.

This feature would probably need to be supplemented by a new Settings/Tally Lights/ "SetTally shortcut Enabled" (or something similar). Otherwise there would likely be conflicts between the Tally controlled automatically and the one controlled by SetTally.

There are a number of reasons why I regard this shortcut a valuable addition, including these five:

1. For some editions vMix 26 will support an increased number of Mix Inputs. SetTally would solve the problem that Mix Inputs currently does not support Tally. As, for example, reported in https://forums.vmix.com/...y-lights-with-Mix-inputs and https://forums.vmix.com/...-Tally-work-with-mixer-2

2. It overcomes the limitation that currently tally numbers must be tied to the actual Input number. I do not really see the reason for why this is so. It forces us to put Inputs on certain number positions, when we quite frequently want them somewhere else.

3. Sometimes I want to force a Tally on when that Input is neither in Preview nor Active. A typical use is when the producer wants the talent to look in a certain direction and have a profile shot Active.

4. I can also imagine situations when one wants to have a more flexible and programmable control over the tally. Compare https://forums.vmix.com/...Tally-Lights-via-actions

5 Last, but not least ;) I still find it useful to be able to not use tallies for PreView, discussed in https://forums.vmix.com/...o-disable-Preview--light
