I created this synthesized effect using a Korg MS200 Analog Modeling Synthesizer. I often use this instrument with the external sync enabled for arpeggiation and and tempo delay processing. The delay does some strange things with the external sync enabled. As you adjust the delay time it jumps from different units of time within the tempo including triplets. This can produced some future dub, spaced out, synthethized effects when the feedback is up all the way.
