In my humble opinion the alternative dry = silentstage and wet = synchron simplifys reduce the different character of both projects in a more or less false way:
The silentstage is no at all "dry": it is a studio ambiance which gives room enough to add additional tools for an artificial ambiance.
The Synchron Series is not at all simply "wet" or only meant for those who always expect the whole ambiance being part of the recorded samples: The Synchron-Studio is also a Studio (with obviously long tradition as Filmscoring studio). Yes you do have in Synchron series a very detailed acces to controle the anount of the real studio ambiance which should part of the recordiung you are programming. But it is also in this meaning still a studio, that nothing prevents you from adding aditional tools for shaping the ambiance you are looking for. Moreover already the Synchron-Player and many of its presets ad an artificial algorithmic reverb, while as long you run them in VEpro you can of course place everything you get out of a synchronplayer in your MIR or any other aditional ambiance tool.
In short: Synchron is not "less" possibility it is just "more" and that means in many aspects (not only the ambiance) much more details available and the more the whole series will be released I am sure exactly this aspect will become more and more obvious.
