Trigger to follow sample slot?

[XORadmin]

Hello, wondering how does one go about having a trigger fire, dependent on a sample slot state? 

For example, sample slot 5 hits, track 1, trigger also fires. 

Does it have to be the other way around or is it not possible at all? 

Thanks.

You could just add a trigger in the fx column where the sample hits.
Or maybe use an envelope and a MOD or CV output instead to generate a trigger based on a sample.
