Heaviest-sounding MIDI triggerable bass modules?

Here’s a good selection which can be triggered over MIDI from a keyboard, pad controller or bass guitar with MIDI converter box: Moog Minitaur or Sirin, Waldorf Pulse 2, Moog Slim Phatty, Korg Volca Bass. These all have plenty of low-end grunt and girth to really give that deep, low extended power that can shake rooms and your audience!
