Thread: Mid/Side processing in modular
It should be out there somewhere. Have you tried looking for a used copy via Amazon? I often find that 'difficult to find stuff' turns up there routinely...you just have to be careful to avoid the collector-dealer types so that you don't wind up paying twice the price.
As for "Kontakte", there's actually TWO versions of it...and you can get both via the Stockhausen-Verlag website. Their editions are more expensive than others, but the MASSIVE liner notes (by Da Man Hisself!) on every work in the series is well worth the cost. Anyway, there's a version that's ONLY the electronics, and the other with piano and percussion. Both are 100% worth having. http://www.stockhausen-verlag.com/
