A simple 303 loop (not an actual 303, it's the nekobee softsynth). I recorded it in fixed point with a much too high input volume, so it was very distorted. It sounds kind of cool. You may use this sound for any purpose without attribution.
A distorted arpeggio with sharp release and long sustain used as a background layer for an a-ha moment in a film. Used a roland groovebox self-record utility straight to wav, which is pretty good, though it results in quieter high frequencies.
