I use the V-Drum for 3 years and am overjoyed that I had all the VCU gnration of the 2nd Batt Elec (I had a MidiDrum). The mesh pad is a rgal wrist, the sensitivity of the dynamics and the concept works flawless in COSM paramtrage sounds (Tone with the evolution of the intensity or location of the strike). Remains that today that Roland has not been satisfactorily resolved (I think) for the cymbals, and am still not convinced by the new CY. The problem of the cymbals (difficult modliser I should) is that one wants to crash on the edge, but also crash or ride cymbal on the body, and the sensors are took a little default. I do not know if other brands have found the solution or if it exists in the TD20.
Still, the hardware is expensive, but it has a good glove in the field of e-drums! And again I resigned, a note for beginners V-Drum, the output of the TD20 is expected to open the second hand market for TD10, enter the opportunist!
