Speaker Rattling Filter Sweep Saw Octaves

This is part of the bass line from a synthesizer waltz that I’m composing. The sound was played on the Roland Juno-106, which I can’t seem get enough of these days. No processing was applied. All you hear is the chorus along with the LFO modulating the VCF for a long, slow filter sweep. Oh yeah, and I was manually tweaking the cutoff, and probably the envelope amount as well.
