A very affordable yet powerful DTX configuration.
The DTX500K kit is built around a tone generator that has 427 naturally sampled acoustic drum and percussion voices, including Yamaha oak, maple, beech and birch drum sounds. The versatile module includes MIDI; a metronome; Groove Check and Rhythm Gate training functions; and an aux input to play along with your favorite tunes. Velocity-switching samples that change their sound characteristics as you play harder provide enhanced realism. There are 50 preset kits as well as the capability to program your own custom user kits, with digital reverb effects and EQ to sweeten the sound. The DTX500K pad set includes cymbals, snare, 3 toms, a hi-hat pad and pedal controller, and a kick pad with kick pedal. The DTX500K features traditional electronic rubber practice pads that have a nice stick rebound without being too bouncy. The module is compatible with the DTX-PADs so upgrading the kit is very easy.
The songs of the DTX500 let you play along in different styles with or without the recorded drum track, solo the bass player, or with the full ensemble to make playing fun and practicing seem more like a band rehearsal.
Yamaha’s popular groove tools have set the standard for educational functions that are not only easy and fun to use, but actually help you become a better drummer. The DTX500 has a collection of training functions including the popular Groove Check that displays whether you are playing early or late, so you can more easily correct undesirable habits. Rhythm Gate is like a drumming game that automatically mutes the sound if you playing is too far out of time, so you quickly learn to control your groove and play “in the pocket”. Practice has never been this much fun!
The cymbal pads of the DTX500K are compact yet deliver a good feeling and stick rebound for practicing cymbal playing techniques from pianissimo to forte. The DTX500K features a hi-hat system that uses a remote hi-hat pedal controller (included with the kit) and trigger pad to provide realistic hi-hat expression. The pedal and pad can be located anywhere around the kit, much like the popular remote cable hi-hat systems for acoustic drums. Moreover, the hi-hat can express various styles of play such as open/close position, closed pedal and foot splash. For peace of mind, even after purchasing the kit, you can expand by adding up to four pads if you want more toms, cymbals or a double-bass configuration. All kinds of upgrades including support for the DTX-PADs are possible.
The DTX500 includes an audio input for connecting an external music player to the module so you can play along with your favorite music, either though the main output or in your headphones, so you can quickly master the piece you want to learn note for note. A high-performance, programmable metronome made for drummers that allows complicated rhythms and tones to be set. A MIDI output port gives the kit connectivity to additional devices or a computer* for music production applications. *Computer connection requires MIDI interface (ex: Yamaha UX16 USB-MIDI Interface)
The RS40 rack system comes pre-assembled for easy setup and offers solid performance in a light weight, fold-able design for easy storage.
