It’s a Keyboard/Midi controller: a keytar. The Vortex features a three-octave keyboard transmitting both velocity and aftertouch, wrapped in a sleek high-grade plastic case—think fancy laptop. The rubber buttons and trigger pads have a nice tactile feel, and most sport blue LEDs at their edges, a nice detail when playing on dark stages. As well as the 37 keys, Vortex also gives you a MIDI-assignable accelerometer that can be triggered by tilting the neck, eight drum pads, a finger-controlled MIDI-assignable touchstrip and volume, sustain and pitch controls.
According to several user reviews, they have praised Alesis Vortex for the solid build quality; Large variety of assignable MIDI controllers including a ribbon and accelerometer (neck tilt detection); Control assignments and splits are easy to make and can be saved; Keys sense aftertouch. Also, some users have complained it for no internal sounds; it’s a controller only; Accelerometer has somewhat fussy tilt response.
