I have the above program on a Windows XP system with a Soundblaster Audigy LE sound card.  Because of some other system issues, I now have a Windows 7 system for a desktop.  Questions I have:

1)  Will this version of Music Maker work in Windows 7?

2)  If so, does it ABSOLUTELY have to have an extra sound card to run?  The computer has Realtek Sourround Sound on board (and the jacks in the back to prove it), so I have no problem with performing online on karaoke websites (it has Stereomix, the Win7 version of "what u hear").

Thank you for your consideration.
