A No-Compromise Keyboard

You've invested in MIDI sound modules, and software synths. Isn't it time you got the most out of them? The A-37 gives you 76 velocity-sensitive keys with channel aftertouch, allowing you to play your gear to its full potential—from expressive velocity switching on drums to filter cutoff via pressure on synth sounds and more. The A-37 also includes Roland's unique combination Modulation/Bender lever, a favorite among keyboard players.


The A-37 is compliant with the latest MIDI specifications including the GM2 standard, making it particularly useful for desktop musicians or for those who use General MIDI modules. What's more, you can save up to 128 User patches using two keyboard zones—great for live performers or setting up splits and layers. And with its easy-to-use LED display, assignable Data Entry slider and convenient front-panel buttons including Sequencer Start and Stop, Transpose, Clock TX and more, the A-37 can simplify even the most complex MIDI rigs.

With its streamlined modern styling and lightweight design, the A-37 fits neatly into MIDI studios of all sizes and is easily transported. In fact, this infinitely useful controller even runs on batteries if you like. And owning an A-37 is easy, thanks to its ultra-affordable price tag.
