We used drumagog about 5 years ago live, with an M-Audio FastTrack Pro card. We didn't even use midi, we used kick mic to an insert, then off to a DM instance in Cubase. On stage it worked well, but we had to tweak a lot in-between shows (constantly adjusting the insert fader or the sensitivity scale inside DM cause kicks were either not getting enough sensitivity or doubled). If you use it, obviously use a midi trigger.
We switched to an Alesis module after a few shows cause we grew tired of tweaking it all the time.
