Thanks for the replies. Maybe I need to read up on Wersi and other computer based arrangers. But, I still would like to understand the receptor alternative, especially if it adds the ability to call up any VST instrument using a MIDI message. This feature alone makes it more usable than the software based VST hosts, although I do not know for sure that such software hosts do not exist... I just like the fact that receptor is all one box and do not even need a screen to use it if is it configured to load all necessary instruments. Plus, it has inputs for a mic and guitar if you want to use effect plug ins. Also, NAMM is around the corner and we should possibly see more advances in the "virtual instrument" arena.

Thanks.
