I wonder if anyone has found a good method of achieving the following:

I've been working on a couple of songs recently, namely "Tie a yellow ribbon..." and "Thank you for the music". Both these songs have a slow down in tempo at some point in the song ie: in Tie a yellow ribbon it comes at the point in the song where Tony Orlando sings "Now the whole darn bus is cheering, and I can't believe I see....."
In "Thank you for the music...." it's at the point "I am the girl with golden hair...". At these measures in the song it's not enough in my opinion to just cut the drums out of the style, i'd like to be able to reduce the tempo on one of the variations automatically.

Is the above possible, or if not, has anyone found a good way of achieving the above?

Many thanks in advance for any help

Kind regards to all

Peter
