The Roland RMP-12 Rhythm Coach offers an exciting dimension of portable sound and expression, geared toward marching applications. The RMP-12 is the world's first electronic marching percussion instrument to incorporate Roland's patented multi-layer mesh head technology, giving drummers a real-feel, and allowing drummers to practice late into the night. Mesh-Head Comfort The Roland RMP-12's patented mesh drum head provides low acoustic noise, high durability, and unsurpassed comfort. Head tension can be adjusted with a drum key, just like an acoustic drum, for the perfect stick response. The head is also replaceable, like an acoustic drum. World of Sound This enhanced drum pad from Roland offers high-quality marching snares, toms, bass drums, cymbals, and other drums and percussion instruments. It also contains a variety of Latin percussion as well as electronic sounds. The four memory buttons let you store your favorite sounds and call them up instantly during your performance. Rhythm Coach Onboard The Rhythm Coach helps you build speed, stamina, and accuracy. Even if you're not in the Rhythm Coach mode, you can practice with the Time Check whenever you start the metronome. The Time Check Score, which grades accuracy, is one of the menus in the Rhythm Coach. Other effective exercises include the Auto Up/Down, which gradually speeds up and slows down the metronome, and the DynaMeter, which shows your stroke dynamics on the screen. Marching Percussion Perfect for extended wear, the RMP-12 Rhythm Coach is lightweight and battery-powered. It can be attached to standard marching drum carriers for wireless transmission, allowing you to freely move around during your performance. For practice, mount it to a concert snare stand and use an amplifier to monitor or simply connect headphones for quiet practice.
