Bad Snacks demonstrates how to layer a percussion audio loop on top of a programmed MIDI drum pattern in Ableton Live, pulling a free loop from the Beat Selection pack by Sample Magic. The key detail: look for "top" in the file name, which signals a loop containing hi-hats and percussion designed to sit above a kick and snare.
After dragging the loop into the session, it comes up short relative to the MIDI loop, so a quick Command-D duplicate brings it to the same length. Then a tempo mismatch surfaces: the loop was made at 128 BPM, but the project is running at 120. Rather than a problem, this becomes a chance to explore Ableton's real-time tempo control, landing at 130 BPM where the combined layers feel right.
