All I want is to change style of my song from 100bpm funk beat to 200bpm bebop for B in AABA,somehow I managed to do so,but it was pretty clumsy and didn't seem quite right and on the top of all that I forgot how I did it

.So is there any fast and simple way to do it?
PS:Honestly, I really don't dig BIAB interface,struggling with it all the way,dispite it the programm is really great and irreplaceable.
PPS: Sorry for my bad english,I'm from Russia and don't speak it very often.
