    Product Description

    Put simply, the Arturia KeyStep 37 is a 37-note keyboard controller with a suite of hands-on MIDI controls, smart sequencing and intriguing scale/chord functions. You'll be using these tools, as well as an impressive responsiveness and streamlined workflow to craft your own signature sonics in no time at all!

    Meticulously Designed 

    The bedrock of the instrument is a 37-note keyboard with aftertouch and velocity sensitivity. When played, RGB LED keyboard indicators provide simple and quick note tracking at a glance. This is then combined with a 64-step sequencer (with 8 patterns) and 8-note polyphony (per step). A sleek control panel - equipped with 4 knobs with an LED screen - ensures you have the MIDI-altering capabilities and tools required to get any job done.     

    Creative Centrepiece 

    Arturia have designed the KeyStep 37 to be the central cog in your setup. It's robust and compact build, paired with wide-ranging connectivity options ensures that it's compatible with a range of external hardware and software - no matter where you find yourself. 

    Use the MIDI over USB to take charge of your VST instruments; connect synth's using the MIDI in/out; harness mod, gate and CV pitch connections for seamless integration of modular gear; utilise analog sync in/out to ensure your work remains in time - the creative possibilities available to you here are almost endless. All of these options can even be used at the same time! 

    Tactile Tweaks 

    A selection of interactive controls make your music-creation both fun and intuitive. Experiment with Chord mode, where you can select from 12 contrasting chord variants and strum effects. These voices can be moulded into dynamic, evolving velocity sensitive sections which reflect the response of stringed instruments. 

    This is augmented by Scale mode; this allows you to map the 3-octave keyboard range using your preferred scale. When a key is played, this then quantises automatically with the closest note in the scale you've decided upon. 

    You can also use the assignable 16 MIDI CC parameters (working across 4 switchable banks) to fully unlock the potential of your MIDI software and hardware. 4 new controls let you tweak and alter a multitude of settings while you play, making for far more interesting performances!

    Mr Steve Manklow18th May 2022

    This is PERFECT connectivity-wise for what I need as both a soft-synth and Euro-rack musician. Having played with it extensively my only regret is that I didn't splash out on the 4-track Keystep Pro!

    Mr Graham Bloodworth4th Feb 2022

    The keyboard is solid, weighty, due to the metal base plate. Four stars may sound cruel, but the lack of a manual, or quick start guide. At 62 years of age, it's not plug and play. I should say it will be a fun learning curve.

    I love it. It's probably a modern classic for midi controllers at this point.
