Alesis QX49 USB MIDI keyboard controller at a Glance:

Ideal size

The Alesis QX49, with its 49-note keyboard, is ideal for two-handed performing – while remaining portable. The QX49 gives you a bevy of controls, including pitch and mod wheels, octave up/down buttons, and the facility to send program changes right from the keys. The keyboard can even be split into sections to control multiple instruments simultaneously.

You’ve got connections

The Alesis QX49 includes both USB-MIDI and traditional MIDI ports for instant connection to Mac, PC – and MIDI hardware. The QX49’s MIDI DIN jacks include one for sending MIDI data from the keyboard and another for routing MIDI data from a connected computer. The QX49 can also be powered using a wall power adaptor (sold separately) when not using a computer. You also get a sustain pedal input on the back panel.

Big-time versatility

The QX49 ships with Ableton Live Lite Alesis Edition software for performing, recording, and sequencing music right out of the box. With its traditional MIDI ports, the QX49 is also a great choice for controlling MIDI hardware. Integrating a computer into your live set? With its petite size and light weight, you can place the QX49 a tier above an existing workstation for streamlined optimization of your expanded road rig.
