The Building Blocks of Professional Music Production

The Alesis VI49 is an advanced USB/MIDI keyboard MIDI controller that lets you take command of your music software with a series of pads, knobs, and buttons. With 49 velocity-sensitive semi-weighted keys with aftertouch and Octave Up/Down buttons, you can expand the keyboard to the full melodic range and play bass lines, chords, and melodies. VI25 also features 12 assignable knobs and 36 assignable buttons for manipulating effect plugins and virtual instruments: open and close filters, adjust volume levels, activate effects, tweak parameters, and more. 16 velocity-sensitive RGB trigger pads allow you to launch clips or finger drum with exceptional response and colorful visual feedback. Plus, pitch and modulation wheels expand the expressive capabilities of your performing.

Plug-and-Go Software

VI49 was designed to seamlessly and effortlessly integrate with your music software. A single USB connection to your Mac or PC provides both power and MIDI functionality, allowing you to plug right into your computer and start making music. With the 5-pin MIDI Out, you can also use VI49 to control external MIDI modules, synthesizers, and more. A LED screen and illuminated knobs, buttons, and pads provide real-time visual feedback and are laid out for an intuitive workflow. Plus, VI49's compact design makes it easy to take this advanced MIDI controller on the road or implement it into any sized studio.
