Here's mine, it's about 2 mins long ... I could let it go on forever and ever.
I just hit play and let the LFOs do the work.
Here is how it was done,
Track 1 - sliced the sample and pitched it down using Pitch and slowed it down using Rate. Comb Filter and Phaser for effects.
Track 2 - neighbour machine with Chorus and Reverb for effects
Track 3 - neighbour machine with Lofi and Delay for effects
Recorded into Ableton and applied some limiting to increase the volume a little.
