Eventually, that is the future.

I don't know for instance how close vArranger is to be using complex VSTi sound modules, but as many other examples, the technology will lead us to using smaller and smaller devices, for more and more powerful applications. Everything goes software. Arrangers cannot be an exception, it's just that for now the big R&D departments seems to still prefer going the old verified route - maybe they actually try to get the most of it, before jumping to the future.

Fact is, the VSTi have developed to a level where 10 years ago not many believed they will. Progress I guess. It is a shame the arrangers wouldn't take advantage, but I realize it's a titanic task to actually write the code needed for this. Maybe not even possible for now... but it will come.

That will happen when big companies will take it on board. The small companies cannot really produce the change, I don't think. Unless their product ends up in Big companies portfolio.
