Hi Bill,

Thanks very much for that info.  Have you any idea when (if) an  
upcoming version will support 7.1?  It is quite important as I will  
be purchasing several high-end desktops for the lab and I need to  
know whether to get Macs or pcs.  My preference is for Apple, but I  
simply must be able to control at least 7 speakers.  I've got this  
working fine on our existing PCs.  It would be nice if it worked on  
Mac as well.

Cheers,

Matt Tata
