Ironic how Soundblasters have on-board synth module (E-MU), which seems like a great option, yet they miss the boat as a high-end sound card, and what other cards like Delta 1010 has in features and specs.
For the low-tech / home / not-too-serious or broke musicians out there, a SB using soundfonts is a great "starter" set-up, before investing in more expensive high-end sound cards, software, plug-ins, synth modules etc.
If you simply want to play midi tracks (backing tracks), and add yourself singing and playing guitar, for example, and record in stereo on PC (quick "demo") ... a SB Live for $35, with its bundled software, isn't too bad to experiment in the digital world of recording.
