Oh, I don't think that is a problem, most soundcards have a selectable input,
you can generally set it to record from several sound sources, including the
wavetable.

Yes, this is a very good use of soundfonts, there are some excellent fonts on
the net for old drum machines!

I'm not sure you said what soundcard you had, but with four separate synths it
sounds like an sb-live right?
It was a while since I tried this (I generally run fluidsynth which also uses
soundfonts), I think they use the same "synth engine" though, so they have
the same sounds. You can have a different sound for all 16 midi channels
though, I recall it is somewhat hard to load fonts on all channels though,
quite a bit easier with a softsynth like fluidsynth (especially with a
frontend like Qsynth or the one in MusE).

This is, as Chris mentioned, done with a mixer application, like Jack-rack
(pending that specimen can output to jack, but I think it does). I think you
could use Rosegarden as the mixer application also, I use MusE like this, add
an input and connect the jack-app to it, this limits the number of apps I
need to keep track of and most settings are stored in one place.
