This might be the best you can get when you want to take VSt's out on stage..
http://www.seelake.com/en/as-overview.htmlThey got a great review on Gemran Music website Bonedo.de
Its much more advanced then the Muse receptor.. its not only host, its also a fullfledged Mixer with high end audio connections, lots of Midi and because its running on Windows, you can even add your favourite DAW and other Windows Music related software
Somehow, these guys fail at marketing their product as noboddy knows about it... Hardly any video's and tutorials out there.
I am posting this on several places, because these guys deserve some attention for their great product.
