This segment of percussion is from a new piece I started on today. To get this sound I used a similar filtering technique that I described in Hummingbird Morse Code on a percussion loop that I had pitched up about two octaves. When pitching up that far on a warped clip in Ableton Live the audio takes on a ratchet like tone. Adding the filtering after that created some low resonant sweeps that add some bass frequencies to the track. I haven’t named the piece yet, so this segment is simply titled Percussion Track, although unlike any percussion I have heard.
