Hmm, are they similar to the (very Zoolook-sounding ones) at around 29m47s (or 32m13s), or the "burpy" ones mainly in the last 15 minutes or so of the track?
I wonder if anyone has ever tried to match those unedited WFC uploads to the videos from July 14th 1990 right before the PLD concert started. I mean, those videos probably don't have a full uninterrupted recording of the track for 75 minutes or so, but I guess that's where you could get the best comparisons from (maybe).
(Also, I don't think enough people give WFC credit w.r.t. being a Roland D-50 masterpiece, I think someone (AERO62, IIRC) found a lot of the WFC sounds from the Roland D-50 basic presets )
