We had our doubts in the beginning, too. During a first session last year I made some elaborate tests, with convincing results: The sound of the organ is really created additive, stop by stop. The digital mixture of single flutes sounds more or less identical to the complete registration recorded in the hall; just the hiss gets louder - and this poses no real problem for the Vienna Symphonic Library.

The only thing that can't be simply mixed numerous times is the initial noise of the opening valves and the bellows (... is this the word ...?), as this is in many cases just one for _different_ stops playing at the same time; but I have a solution for that already.
.... and don't make fun about the idea to bring an organ into the SilentStage - Herb and Michi had (have?) plans to do that! [6]
