The patent pending PUREtouch Electronic Pads were constructed by Pearl and KORG engineers with six layers of material that work together to create the most natural feel of any electronic pad available. Combined with the WAVE TRIGGER TECHNOLOGY, for the first time ever, your choice of stick will impact the sound of your electronic kit. Every area of the snare drum head responds like an acoustic drum from the center to the edge. This ultra-fast and highly sensitive technology partially based upon KORG's groundbreaking Wave Drum allows even your stick choice to make a discernible difference in the sound of your drum. Wave Trigger Technology is fast. As fast as audio. Faster than anything simply trigger based. This speed adds a realism to the playing experience never before available to the e-drummer. Wave Trigger Technology uses parallel processing of your character and your sound and seamlessly layers it with high definition samples of real Pearl acoustic drums to create an end result that is as much a reflection of you as with any acoustic performance. With WTT, sample layers are smoothed, latency is imperceivable, and sensitivity is on a different dimension from anything that has come before. The natural feel from the pad construction with extreme sensitivity created by the Wave Trigger Technology make the PUREtouch Electronic Pad System the new industry standard.
