How to trigger VST's?

[edcito]

I have Superior Drummer and BFD Eco. I want to trigger some sounds just to see how it works with the 2box, I know the 2box sounds are great but I want to try VST's as well.

That being said, I plugged the whole rig Midi out 2box>Midi in usb Audio interface>usb audio interface to mac, launched SD2, selected my audio interface under the midi and audio prefs and....Bang....
All I could hear was a terrible noise when hitting a pad!
I can see the midi section on BFD Eco and SD2 lighting up when I hit the pad so midi is not the problem..Turned off local control as well. I tried every midi channel in the module from 1 to 16 and still the same...
Any advice? maybe I should change something in the fader or mixer prefs?

I unplugged and plugged all midi and usb cables again and boom! problem solved! maybe I didn't plug the midi cable right the first time, all good now!

well, except for the mapping......   Will need to map from scratch.... luckily I don't have 24 pads....
