Hey Ryzard, sorry to hear that you're having troubles, but so far you did step number one right, work with the audio/midi interface that works... The audigy might have all these supposed bells and whistles, but if it doesn't work with your system, it's useless... AS far as Nuendo identifying your control surface, that is not an uncommon problem with softwares... My brother has an M-Audio 88 key controller, and he can't get his software to identify it either... I forget what he uses... So, the good news is that at least you're getting audio...

But that's a good game plan though, do your tracks from band in a box, and them import the midi and audio to reason and rewire with nuendo... Have you gone on the Nuendo site and see what they say about rewiring with Reason?? I have Sonar and I can tell you that even though I can get re-wire capabilities with it, it doesn't always work the way it's supposed to, and a lot of people that use Reason have complained about it... But i imagine you're going to use Nuendo to do vocals and things of that nature... So, maybe some of the problems that people are having won't affect you much, (they can only get 1 sound working) as long as you get it to synch with Reason... So, these rewire problems may be across the board with some apps...
