Arturia KeyStep Mk2 32-key Controller & Sequencer - White Reviews

32-key Slim Keyboard with Polyphonic Step Sequencing, Chord, Scale, and Arpeggiator Modes, Capacitive Pitch and Mod Strips, One-touch Mutation, and OLED Display - White

Fully integrating the appearance and control of the Mk2 line, the KeyStep Mk2 takes Arturia's coveted sequencing formula to impressively modern heights. It all begins with a familiar 32-note Slimkey keybed, complete with velocity sensitivity and aftertouch for maximum sonic expressivity. The KeyStep's notable sequencer and arpeggiator engines remain intact, albeit loaded with one-touch mutation tools, Chord and Scale play modes, and 16 arpeggiation modes that offer more versatile melodic foundations than ever before. Sweetwater producers were quick to note the addition of the Mk2 series’ onboard OLED display and push encoder configuration, making the KeyStep's profound polyphonic sequencing tools even easier to manage on any stage. Finished with an accommodating arsenal of connectivity points, including USB-C MIDI, MIDI DIN In/Out, CV/Gate Out, and Sync I/O connections, rest assured Arturia's 2nd generation KeyStep is primed for integration into your existing rig.

Quality Control Issues not Typical with Arturia Products - On / Off Switch Failure on Second Use

By Pete L. from Washington
Music Background: Musician/Engineer with lots of experience with gear

I own many Arturia products including hardware and software synths and an audio interface, and have had no issues with their products in the past. Compared to other Arturia products, this is cheap plastic and does not feel sturdy. Worse yet, this cheapness extends to a part that MUST be robust or the controller won't continue to work properly. The on/off switch failed on only the second usage for me and cracked on the inside. I can hear part of it rolling around inside the keyboard and it will no longer power on. The thing is, almost no pressure was used on the switch to actuate it on or off, so the part must have already been cracked before I got it :( I'm going to return it and the design is bad enough that I won't replace it with the same model.

Major Upgrade from my Original Keystep 32

By Floyd O. from GREENVILLE, SC

This new MK II version is a major improvement over the original Keystep 32.
Here's why…..


OLED Display & Encoder: Clear visual feedback and fast, intuitive editing of parameters directly on the device, reducing reliance on Midi Center App.
Enhanced Sequencer: Now supports polyphonic steps, pattern chaining, and real-time transformations (Transpose, Double, etc.).
Creative Generative Tools: A new "Mutate" function instantly creates melodic/rhythmic variations, plus "Spice" and "Dice" for live randomization.
Expanded Arpeggiator: More modes, patterns, octave control, and the ability to turn any arpeggio into a sequence.
Improved Connectivity with USB-C, a power switch, dedicated Sustain/Expression pedal inputs, and an extra Mod CV output for modular synths.
Workflow Upgrades: "Arp-to-Seq" converts arpeggios to sequences, and chord modes from the KeyStep 37 are included.
Better Physical Controls: Velocity/aftertouch are adjustable on hardware; redesigned, back-lit plastic buttons feel modern.

Definitely worth upgrading to this MK II
