Exactly, but many musicians are using these kits in the studio these days as the sound quality is so good, and  they bring in many new sounds and eliminate acoustic shortcomings in the studio environment. Many drummers are now incorporating V-Drum triggers and additions into their kits for live performance.

 

i quote -

 

"Shortly after making the choice to include electronic drums and triggers, Peart added what has become another trademark of his kit: his http://en.wikipedia.org/wiki/Image:Neil-Peart.jpg - rotating drum riser . During live Rush shows, the automated rotating riser allows Peart to swap dynamically the prominent portions of the kit ("front", traditional kit; and "back" electronic kit). A staple of Peart's live drum solos has been the in-performance rotation-and-swap of the front and back kits as part of the solo itself. This special effect simultaneously provides a symbolic transition of drum styles within the solo, as well as providing a visual treat for the audience."

"In the http://en.wikipedia.org/wiki/2000s_in_music - early 2000s , (Neil) Peart began taking full advantage of the remarkable advances in electronic drum technology; primarily incorporating http://en.wikipedia.org/wiki/Roland_V-Drums - Roland V-Drums and continued use of http://en.wikipedia.org/wiki/Sampler_%28musical_instrument%29 - samplers with his existing set of acoustic percussion. Peart's digitally sampled library of both traditional and exotic sounds has grown over the years with his music."
