Learn Drums digitally and play perfectly

An Electronic drum is a percussion instrument in which the sound is generated by an electronic waveform generator or sampler instead of by acoustic vibration.

When an electronic drum pad is struck, a voltage change is triggered in the embedded piezoelectric transducer (piezo) or force sensitive resistor (FSR). The resultant signals are transmitted to an electronic "drum brain" via TS or TRS cables, and are translated into digital waveforms, which produce the desired percussion sound assigned to that particular trigger pad. Most newer drum modules have trigger inputs for 2 or more cymbals, a kick, 3-4 toms, a dual-zone snare, (head and rim) and a hi-hat. The hi-hat has a foot controller which produces open and closed sounds with some models offering variations in-between. By having the ability to assign different sounds to any given pad, the electronic drummer has nearly unlimited potential for configuring many different sounding drum kits from one set of electronic drums. Additionally, electronic drummers can sample non-percussive sounds and use them as drum sounds, as is the case with most industrial music. Many see this as a great advantage over acoustic drums, as one can have a jazz, rock or ballad drumset by merely changing the kit selector switch on the module.

V Drums (Digital) : With a full-frequency spectrum of tone, and with enough energy and impact to propel an entire ensemble, the drum set is the true foundation of modern music. But even though drums have steadily evolved, drummers still dream of surpassing the inherent, fixed limitations of the instrument.

"I want more freedom and flexibility in changing the sound of my drums."
"I want the natural beauty of acoustic drums plus the ability to use cool drum-machine sounds, electronic textures, and other effects."
"I want to be able to instantly rearrange a drum kit for every song I play."
"I want a kit that’s sensitive enough to match the dynamics of other instruments, from the softest notes to full, blasting power."
"I want recording-output capability that offers high-quality sound without complicated microphone setups."
"I want the ability to rehearse in a bedroom at night using headphones."

Electronic drums that have appeared in recent years have hinted at the potential, but they haven’t delivered. To truly be called “drums,” they have to allow a drummer to play as expressively and comfortably as they would on a traditional acoustic kit.

So real, so expressive, so powerful and versatile — Roland V-Drums are the first and only electronic drum system to provide the full expressive performance nuance of an acoustic kit married with mind-blowing modern technology and convenience. Components such as the V-Hi-Hat™ and patented Mesh Heads embody Roland's exclusive technologies. The result is a kit that allows drummers to play completely naturally in an “analogue” way. V-Drums have set the global standard in electronic drums for drummers of any level, from beginner to top-level professional.
