Here what Alesis say about the V series controller keyboards
Introducing the new V Series of full-size keyboard/pad controllers. The V series controllers include a Software Preset/Parameter utility that makes setup a snap.

The new Alesis V Series (V61, V49, V25) combine velocity-sensitive keys with eight drum/trigger pads, allowing virtual instruments to be played with dynamic expression. Cool blue LEDs illuminate the pads?as well as the four assignable knobs and buttons?for positive visibility. Assignments may be made quickly via the MIDI Learn feature. Octave shift keys provide access to the entire note range. A single USB cable provides both a power and data connection to nearly any computer.

An optional power supply and a standard MIDI output allow for stand-alone use.
