Yes, you can select a soundfont and play midi files in VLC.

I'm just looking for an easy way to play my MIDI files live on a gig, via a laptop, like I used to do with my old Roland SD35. I believe, from my reading, I need a VST that has general midi instruments in it, so midi files can just load up and play. And I guess I need a player, so I need a DAW, hopefully one that is easy to customize and simplify the interface so it shows only what I need, e.g. tempo change, play and stop buttons. I will look up the TTS-1.
