A more proper name would be Measure reset because Tempo reset is what Yamaha already has. You can easily use SYNC START. Singers who do not know where their first time in the show is to go back to the music school. 
This function is implemented on Tap Tempo/Reset button in Korg, I think from PA50/80, I don't know exactly... I didn't invented it, it already exists on the market!
Sync Start is very hard to use it on a high tempo style, so it's not a solution.
Yes, indeed, is a bad expression of me, because is "Tap Tempo" and "Reset"! So it is "Reset" button. My apologize!
It's not about only the singers, there are songs which have something like 5 or 6 beat in the last measure before fill. It's not only the singer. It's about entertaining, also, if someone came to us to speak with us in realtime playing, we have to reset the style to the first beat to be where it has to be at the moment which singer starts... Also, there are gigs where people came and sing with us, which are not musical prepared, and they don't really know how to keep the beat of style, so we need that Reset function.
But we have to live with that little changes one or two years more, didn't we?!
