Mpc live 2 acoustic drums vat

I’m thinking of purchasing mpc live 2, is there an option for stand alone vst drums on the device without connecting to a computer?

No not really. There actually is no standalone unit that could deal with something like Addictive Drums 2.
Right now, the Ableton Push 3 can load some special Ableton drum kits that do sound like pretty good acoustic drums, but not just any vst.

Maschine + same thing. You can load some vat instruments in there which have been selected by Native Instruments, but not a random vet of your choosing.

Right now for standalone I recommend the Yamaha FGDP devices since they sound decent (onboard drums) and they’re not too expensive.
