Roland A-49-BK 49-Key MIDI Keyboard Controller

The Roland A-49-BK is a compact 49-key MIDI keyboard controller for creating, recording, and performing with computer-based music software or compatible external MIDI equipment. It provides a hands-on way to enter notes and control musical parameters without relying solely on a mouse or computer keyboard. Because it is a MIDI controller rather than a keyboard with onboard sounds, it is designed to control software instruments or external sound modules.

This controller suits musicians, producers, students, and mobile creators who want a streamlined keyboard for a desk, studio, or portable production setup. Its velocity-sensitive keys respond to playing dynamics, helping performances retain expressive control over compatible instruments. The compact footprint helps fit a 49-key layout into spaces where a larger controller may be impractical.

The A-49-BK combines keyboard performance control with direct access to common MIDI functions. Two assignable knobs, two assignable switches, a pitch bend/modulation lever, and Roland's D-BEAM controller provide multiple ways to adjust sound parameters while playing. The D-BEAM controller can be used for pitch, volume, or an assigned function, depending on the selected mode and connected device or software.

USB bus power keeps the setup simple by powering the controller from a computer through its USB Type-B port, so no AC adapter is required for standard computer use. A rear-panel MIDI OUT connection also supports communication with compatible external MIDI hardware. Hold and expression pedal inputs provide expansion options for players who want sustain and continuous expression control.

The A-49-BK fits naturally into a computer music system with a DAW, virtual instruments, and an audio interface or monitor setup. It can also serve as a control surface for compatible MIDI sound modules and MIDI Visual Control devices. With octave, transpose, MIDI channel, program-change, and assignable-control functions, it offers practical flexibility without adding unnecessary bulk.

Key Features

• 49 Velocity-Sensitive Keys: Captures playing dynamics for more expressive MIDI performances.
• USB Bus Power: Draws power through USB without an AC adapter.
• Assignable Controls: Two knobs and two switches adapt to compatible software or hardware.
• D-BEAM Controller: Uses hand movement to control pitch, volume, or assignments.
• MIDI OUT Port: Connects to compatible external MIDI sound modules and devices.
• Pedal Expansion: Supports optional hold and expression pedals for performance control.

Design & Installation

The A-49-BK uses a slim, lightweight keyboard-controller format with a black finish and a 49-key playing surface. Roland specifies a width of 836 mm and a weight of 2.5 kg, making it suitable for desktop production spaces and portable use. Its control layout places performance controls, assignable knobs, switches, and status indicators within easy reach of the keyboard.

Connect the included USB cable from the USB COMPUTER port to a compatible computer, then select the A-49 as a MIDI input in your music software. Connect a compatible MIDI device to MIDI OUT when using external hardware, and add optional DP-2 or DP-10 hold pedals or an EV-5 expression pedal as needed. The controller does not generate sound by itself, so a software instrument, DAW, or external MIDI sound module is required to hear musical output.
