That would be one point of view, and certainly the one that prevails here and seemingly among most synthesists. But it isn't mine. I speak as a musician who happens to play synthesizer. If the synthesizer didn't exist, I'd still be a musician.
If I were to compose an organ fugue and some one were to call it "noise" or an organ "demo," rather than "music," I'd be rather insulted. I write here in the presumption that, down deep, we all recognize the differences.
So, I would much prefer to hear the OB-6 perform a fugue than make noises, since for me there are stark differences. Again, I'm confident that, in spite of these forum complexities, we all recognize the differences, even if talking about them is painful.
