Definitely go MIDI. You just can't go wrong with MIDI, it's always going to
work with everything forever.
As long as whatever controller (conventional or completely insane) you have is
MIDI, you're set. Most all linux audio apps support MIDI control to some
extent, many support MIDI control of almost every possible parameter.
The ones that don't need too anyway, and it shouldn't be too hard a feature to
add.
For a MIDI controlled FX box, you probably want to check out jack-rack (for
simpler chains) or AMS (for arbitrarily complex networks of effects). Both
allow mapping MIDI to most any control (AMS in a really nice easy way too, no
remembering controller numbers etc.)
AMS can supposedly run without a GUI (there's a command line option for it
anyway) even though at a code level the two aren't separated. Not sure about
jack-rack, but I have a feeling it can't.
