The ATV AD5 is relatively new to the marketplace still. We checked them out at Winter NAMM 2017 and were impressed enough to start selling it. It works with several different brands of pads so you can mix and match what you like. It triggers well and the sounds are good. 

• Works with Roland or Yamaha Pads
• Great Dynamics
• ATV Pads in the works
• Good Quality Sounds
