I use a Edirol by roland UA-4fx interface, and currently I use vsc/dxi, forte, and the stantard Realtec audio sounds that came with my computer. Still waiting to upgrade to a better sound card. I sometimes use my Yamaha PSR2000 as a midi sound engine.

the UA-4fx is a pretty cool interface, comes with the ASIO4all, as well as a lite edition of sonar, at least when I bought it. Look up the unit on the internet, it may do what you want. I use it go go direct with my LR Baggs Larrivee, it does have a tube simulator with an xlr mic infput as well and phantom power. quite a bundle.

New I think was $140.00 when I got it. I'm starting to see them show up both new and used on Ebay now.
