First, I am loving the BeatBuddy - this is an excellent product that I enjoy very much.
I’ve been amusing myself over the last few days of learning how to use this product by creating a bunch of old 80’s metal songs to jam to. Bands like Metallica, Slayer, and Iron Maiden had a LOT of tempo changes within their songs, and time signature changes - like a chorus in 6/4 though the rest of the song is in 4/4 for example. And Metallica loves to throw in bars of 2/4 throughout their songs.
Anyway, the only way to handle the tempo changes currently is to break an actual song up into many BeatBuddy songs with a different tempos assigned to each. This makes for non-seamless transitions and makes my SD card a mess as well.
As for the time signature changes, so far I’ve just been smashing bars into 4/4 time until they finish on 4 - not a very elegant solution either but the best I can do at this point.
So TLDR: please add to BeatBuddy Manager the ability to assign meter and tempo to every song part. That would MASSIVELY increase the power and flexibility of this product.
