So, by chance I heard the song Marky & XRS sampled for Butterfly: Roy Ayers Ubiquity- Searching and I thought damn that's nice. I noticed that during the parts which they sampled (the vocal line butterfly and the melody) that there is kit playing. But this kit isn't noticeable during the song. So I was wondering how they achieved this? Did they use some sort of HP filter on the song to get rid of the kicks or what? I would really like to know this as it would definitely expose some potential samples in the future.
