High-Quality Tone Generator That Meets the Demands of Live Performances & Recordings The DTX900 has versatile drum kits that can be used with a variety of genres. Not only does the DTX900 contain the sounds of Yamaha's major acoustic drums, the Oak Custom, Birch Custom, & Maple Custom Absolute, it also contains new drum & percussion sounds recorded by our engineers. Using the DTX-PAD makes even more realistic & expressive performances possible. Also, the XA (Expanded Articulation) System, which creates subtly different samples even when you strike the drum with the same strength, can create more natural snare rolls & accurately recreate to the finest detail the feel of a Hi-Hat or ride cymbal. The DTX900's effects enable you to create the original sounds that you want. These effects include reverb, chorus, 9 types of master effects, & 51 types of variation effects. In addition, you can add original sounds to a drum kit & perform with them by transferring audio data (WAV & AIFF files) from USB (Universal Serial Bus) flash memory or by directly sampling signals received through the AUX IN/SAMPLING IN connector.* You need a DIMM (sold separately) to load & sample audio data. Drummers can expand their expressiveness in a multitude of ways, such as by changing drum sets during a performance (something which is impossible with acoustic drums) or by performing as a one-man ensemble of percussion sounds & effects. The Achievement of Efficient Music Creation through Connection with a PCThe DTX900 comes with Cubase AI, a DAW (digital audio workstation) software application from Steinberg. The DTX900 has a USB (Universal Serial Bus) TO HOST connector that enables you to connect to a computer using a single USB (Universal Serial Bus) cable (sold separately). Even if you aren't comfortable using keyboards, you can input MIDI data & create music by hitting the pads. & you aren't just limited to adjustments of pitch & rhythm, you can also make finer musical adjustments. Also, if you install DTX900 Extension, you can control Cubase AI directly from the DTX900 panel & create music efficiently.
