The DTX900M combines Yamaha’s passion for making the best sounding acoustic drums with their extensive knowledge of digital sound technology. At Yamaha, the sound and the ability to express yourself musically are the two most important things that go into every instrument made. For this reason, the DTX900 series utilizes Xpanded Articulation technology from their flagship series of synthesizer – the MOTIF. This technology involves using lots of samples (digital recordings of actual instruments) to recreate a single instrument voice. In the DTX900 series, Xpanded Articulation makes the drum and cymbal voices sound more natural with subtle variations for each stroke. And with 512MB of memory for user sampling, the DTX900M drum trigger module lets you capture any sound and assign it to the pads for endless sound possibilities.
