Overview

The Roland A-49-WH is a 49-key MIDI keyboard controller designed for musicians who want full-size keys in a portable, no-fuss package. Its velocity-sensitive synth-action keybed provides a responsive playing feel that translates dynamics naturally into your DAW or virtual instruments. Powered entirely over USB, the A-49 eliminates cable clutter and power adapter hassles, making it straightforward to set up in any workspace or take to a session.

Beyond the keys, the A-49 offers Roland's signature D-BEAM infrared controller, which lets you manipulate assigned parameters — such as pitch, filter sweeps, or effects — by moving your hand above the sensor. Two assignable knobs and two switches round out the hands-on controls, providing quick access to frequently used parameters without reaching for your mouse. While the A-49 prioritizes playability and portability over an abundance of control surface features, it fills its niche well as a reliable, responsive MIDI keyboard for studio production, live performance triggering, and music education.

Pros & Cons

👍 Pros

  • Full-size 49-key layout provides enough range for two-handed playing without taking up excessive desk space
  • USB bus powered eliminates the need for an AC adapter, simplifying mobile setups
  • D-BEAM controller adds expressive, gesture-based parameter control not found on most competing MIDI keyboards
  • Lightweight and compact build makes it easy to transport between studio and stage
  • Velocity-sensitive keys respond to playing dynamics for more expressive performances

👎 Cons

  • Synth-action keys lack the weighted feel that pianists may prefer for realistic piano playing
  • Only two assignable knobs and two switches, which limits hands-on control compared to knob-heavy controllers
  • No built-in sounds or audio interface, so it requires a computer or external module to produce sound
  • No pitch bend or modulation wheels — these functions are handled through the D-BEAM and buttons instead
