I would suggest you look at this thread …
Personally I have the Alesis Triggerio
(and goodness ain’t they similar … 
)
which I’ve used not strapped to a drum kit yet but have triggered from 6 metronomes (Don’t ask, it didn’t really work but that not the Alesis’s fault), and that gives you the kind of Pre interface dynamics control ( think MIDI pre-amp) that as you say, you need in this kind of area.
The Led Zep drums are played from a zynth but the midi file is played by Audacity via the Zynthian qmidinet adapter.
It’s the RedZeppelin Drum set . . .
