«  Excellent versatility »

I use it for three months in home studio for parts of drum and percussion.
Pros:
- Touched very accurate and pleasant
- Approach percussionist (smothering the skin, toe)
- Can be configured as desired (position of sounds, but also pitch, sustain (muffling), effects, MIDI mapping, etc ...)
- The d-beam a little gadget but fun
- The possibility to connect to the hi-hat pedal and bass drum
- Audio Input
- The quality of sound
Cons:
- The quantity of sounds (gotta actually faster around)
- The inability to assign the edge of the pad (for layers ...) to a separate MIDI controller
- Play with chopsticks (possible but not for that)
- Menus and submenus not practical (as usual with Roland)
- The look a little toy (personal opinion)

The value for money is difficult to assess because there is no real competitor to share the recent Wavedrum korg that will satisfy most of the percussionists hardliners. The price seems justified given the opportunities and overall quality.

With the experience I might have taken the HPD-15 (more sounds) ... and damn I was afraid to write it one day ...
