Can you have two different tempo's running simultaneously?

Question

I am sure someone out there has had this following problem:
You create a melody, love it at the tempo its in, but you realize everything else (particularly the drums) must operate at a different tempo. In my case, the melody is running at 60 bmp and I need everything else to run at least at 80 bpm. Setting the region containing the melody to play according to the project tempo changes its speed so this and its reverse do not work. Time stretching did not work as well. I realize that I am essentially asking for two tempos to operate in sync which seems impossible but maybe someone can help? Please remember I am new to this so there may be something I don't know or haven't tried.
Thank you for the time and help.

Answer 1

Aside from not being able to have 2 tempo's at the same time in the same project, I think you are maybe talking about time signatures.
There is also a half-time feel, for example if you had a 120bpm metronome going you could play at half time which would mean, essentially, what you were playing would also fit a 60bpm metronome.
If you had 2 tempo's, one would always be chasing the other. It's not really going to work. You can have, though, a 5/4 signature where, say, the bass and guitar play in 5/4 and the rest of the band play in 4/4. It's odd and jazzy but in this example every 20 beats would begin the cycle again.
This is the only thing I can really think of without hearing what you mean.
