I'm not sure if anyone can answer this question for me, but I've been SO curious about this.
There is a production track that [as] used a few times called Hi-Lands that features an electronic texture that is almost identical to one found in the track Japanese Gum by Her Space Holiday.
However, it doesn't seem that either artist sampled the other. Not only are they pitched differently, but Japanese Gum contains other ambient keyboard sounds that play over the texture, which are not heard in Hi-Lands. Also, Japanese Gum could not have sampled Hi-Lands because the version of the texture in Japanese Gum is drawn out a little longer.
So my question is: Does anyone know what the true source of this sound is? If neither of these artists sampled the other, then I'm guessing the sound would either be from a sample library or on some sort of VST instrument as a preset....Or I'm totally wrong and it's just really good sample manipulation on the part of Hi-Land's producers.
Anyway, I apologize for the long post....This is just something that's bugging me. haha
