I used a fork to hit a aluminum pedestal (tubular) and searched for a sweet spot with a natural resonance. One preset it is made from this sound.
The 3 other presets were variations created with effects and looping (inside Decent sampler).
The idea was to create a swarm of metallic sounds. All tuned musically.
