You need a portable USB MIDI controller but also want a keyboard that provides a musical playing experience? You have some MIDI modules you want to connect as well but don’t want the footprint of a large keyboard? You have modular and analog gear you want to control via CV/GATEs? You want a step sequencer with polyphonic capability that can sync to your favorite modern and vintage gear? If only a single piece of gear could do all of this…

Whatever your setup, KeyStep will merge into it to overdrive your workflow and effectiveness. With KeyStep and its range of connections you can control any digital or analog synthesizer from the past, today and even tomorrow. Sequence them all!

Three modes of operation!
In Sequencer mode you can record, play and transpose a polyphonic sequence with up to 64 steps and 8 simultaneous notes per step. Sequencer mode also allows you to rewrite in real-time your sequence and even to play and sequence simultaneously on two different MIDI channels.

The arpegiattor allows you to play each note of a chord consecutively instead of simultaneously. The eight possible playing directions and the Time Division knob will enable the creation of complex and mazy melodies.

KeyStep stands up to most of the bigger keyboard controllers thanks to its prolific array of features including a custom 32-slim-key keybed with velocity and aftertouch, highly reactive pitch and modulation capacitive ribbons and above all the possibility of controlling almost every type of synthesizer by MIDI and CV.

Arturia started by designing their own “slim key” keyboard action, balancing the best features of compact mini-keys with the musicality of full-sized keys into this new keybed. The size, velocity and aftertouch of this new design provide the freedom of portability without sacrificing playability.

They also designed a new polyphonic step-sequencer with 8 programmable memories that you can recall at the turn of knob. You can choose gate times and swing settings instantly to change the feel of your sequenced performance on the fl as well as the ability to record, overdub, and transpose your sequences in real time and still play the keyboard live.

Plus the three CV outputs send pitch and gate signals along with velocity, aftertouch or mod. ribbon signal to control an analog instrument or module. Add a flexible and fun arpeggiator mode and chord play mode and you are set for hours of musical adventures!

Perfect addition to any other synths or modules


Works great using it to bypass my volca bass and mother 32 keyboards allows me to make more complex melodies and it cleans up my workflow a lot! I highly suggest it if you have synths that have over complicated sequencer systems, the price is cheap so if you are simply trying to elevate other low priced equipment to a more professional level!



Excellent build quality


I didn't expect the build quality to be as good as it is on the Keystep. I now get why this midi keyboard is so popular and in so many videos (connected to just about anything).



Best value out there !!


For the price you can simply not beat the keystep. With a built in arpeggiator, sequencer, and after touch this can serve as a hub for all your synth modules or other midi devices.



Best Keyboard in its price range for synths


Great keyboard with after touch. Also has CV inputs to control hardware synths. Size is small enough to fit in a larger backpack making it somewhat portable as well.



Great contolle for software or hardware!


The Arturia Keystep is a fantastic little midi controller with a plethora of features. It makes a great controller for software with its micro USB bus powered connection, and its velocity-sensitive keys are equipped with aftertouch! The keystep features an integrated arpeggiator and sequencer, both are incredibly easy to utilize. If you're looking for a hardware controller look no further! The CV outputs on this keyboard are perfect for going into analog synthesizers to trigger gates and pitch values, and you also have 5-pin MIDI connections for more standard keyboards and synths! This little guy does it all, and you can even arpeggiate or sequence instruments that don't have those features. This is a Sam Ash Employee Review.
