This is coming along very well. I found a Dominican Merengue instrument package that had a couple sample loops. I’ve also made a midi file of the loop from the video where the pattern is written out.
I was able to download the song file you linked to on YouTube, and I have separated out the drum track with a stem splitter. I found 13 sections of the song that sounded good to make loops with some variations in them. All told, you should end up with around 20 midi parts that you can mix and match into songs, along with a custom drum kit that has Quinto, Conga, Tambora and Dominican Guira.
It will take me a bit to get it done, but it’s in process.
