Does anyone know if you can put different time signatures in the same song.
I have a song I am working on that starts 4/4 then switches to 3/4.
I have tried changing the beginning to 3/4 but it just doesn’t sound right.
Thanks
You can have different song parts (including fills, transitions and intro/outro) with different time signatures.
You cannot, however, have a time signature change within a single song part, though.
Just split your song you want to play with the BeatBuddy into parts in such a way that there is no time signature shifts inside a single part. Then you are good to go!
Hope this helps 
That definitely helps, now I just have to find the time to learn how to use the Manager software and see what I can come up with.
I start off the song with I believe 18 measures of 4/4 then go to 3/4, then go back to the 4/4 section for the middle, then 3/4, then end the song with the 4/4 section.
I’d recommend you check some tutorial videos of @Psalm40. They should definitely help you start with the BBManager!
