With the Alesis VX49 USB/MIDI controller keyboard, you can load up your favorite software synthesizers, samplers, and drum machines as if you were working on a standalone keyboard workstation. The included VIP software scans your instrument plug-ins, indexes all of their presets, maps out the controls, and allows you to switch sounds and tweak parameters on the fly — without ever touching your mouse. With 49 velocity-sensitive keys (with aftertouch), eight pressure-sensitive pads, eight rotary encoders, and a built-in arpeggiator, the Alesis VX49 could be your ideal controller for production and performance.
