USB MIDI should work to Casio also, if you want that option.

I like the 12 meg Chaos soundfont as a starting point. Size wise it's not too heavy, easy to install and modify.
The MIDI to the card itself should work so you can play fonts. The gameport not working often means the MIDI connections from that gameport wire assembly aren't going to work either.

Recording the sound back in as you described is how you will have to do it. The Creative cards don't 'render' like a softsynth, but they do record back in, once routed (enabled) in the Creative mixer.
No need to go out to a mixer, it is all done digitally inside the Creative mixer.


I do not work here, but the benefits are still awesome
