Reply to Remaking samples - copyright question

Say there's a 4 bar loop in a song that I want to sample and chop for use in my own track. I know I could run into issues regarding copyright if I were to sample straight from the song. However, would the same issues arise if I were to recreate the sample (using vst's and/or my own recordings) and then chop/sample my own version?

I understand that copyright applies to the artistic work as well as the actual recording but I am unsure if that still applies when recreating a small portion of a complete song.

Thanks!
