Thank you so much. I am not familiar with Minihost Modular, so need time to look at it.

To clarify, I actually use BIAB to generate the desired chord sequence for the whole song. Then I will drag the files to Reaper to record vocal and mix.

I'm interested in the loops fuctions. In my imagination, if BIAB can make a new chord progression out of a slick loop from Big Fish Audio (just an example), that would be great. As you know, for loops, often you cannot change the chord progression or you can only do that in a very difficult way.
