Tempo in a vst~

Dear all,
a little question about the vst~ object:
Some vst effects, such as "supatrigga" or other tempo-delays, require, to work properly, the tempo in BPM of the VST-Host.
Otherwise, they don't work at all.

How may I send this BPM-Tempo if I use these kind of VST inside Max?

Thank you all,

Bruno
