Live Band information The lates news for live band

I bought the Boss DB 90 but it’s a little confusing ando don’t think it’s going to suit my needs because my band has different time signature changes and tempo changes sometimes in the same song.

I need something where I can program how many bars have a certain tempo and time signature and set up different song presets.

Does anyone know what to buy that will do this job?

Thanks.

Originally of course, you need to go for any various anyyourself, but that doesn’t necessarily mean that you must actually go through with it once it has been chosen
