VST Sampling: What do Low Key and High Key correspond to?

[Satie]

Hi there,

I am trying to sample a VST but I don't understand how the values for Low Key and High Key relate to the piano?

The Image-Line video tutorial just tells you to leave the defaults (24-96) if you don't know what you're doing but this is not sampling every key from the VST I am trying to sample. When I set the values to extremes (e.g. 0 - 120) then I get lots of unnecessary files which are just pitched versions of the final playable key in the VST.

Does anyone know how these numbers relate to keys on the piano previews or FL piano roll?

Thanks very much
