Arturia Keystep 37 Controller Keyboard and Sequencer Overview

The KeyStep 37 takes all the best features of the KeyStep and builds on it further. It sits in the middle of the Arturia Keystep Range and is one of the most feature-packed MIDI controllers available. If you’re looking a MIDI Controller that is easy to use, robust and seamlessly integrates with your studio setup via USB or sync with your external hardware via MIDI/CV, the KeyStep Range is for you. The Arturia KeyStep Range all come with a free download of Ableton Live Lite, an accessible music-making suite for your Mac or PC. Just register your KeyStep to receive your free download and get creative right out the box and let the music flow.

All Arturia KeyStep controllers have velocity-sensitive Slimkeys (32 keys on KeyStep and 37 on KeyStep 37/KeyStep Pro) with AfterTouch, a built-in Polyphonic Sequencer (8 note polyphony on the KeyStep/KeyStep 37 and 16 note on the KeyStep Pro) with 8 pattern slots (16 on KeyStep Pro) per track (1 track on KeyStep/KeyStep 37 and 4 on KeyStep Pro). Also, there are 8 Arpeggiator modes (7 on the KeyStep Pro) and all versions have Chord Memory, which transforms a single-note melody into a chord sequence, at the touch of a button. Use the 4 new controls to choose from 12 chord voicings, including a user-defined chord, for distinct harmonic flavours. On the KeyStep 37, Chord Memory even has time-based strum effects, simply select the number of notes per chord and adjust velocity sensitivity - the harder you hit, the more notes you’ll hear.

Integration is key for any MIDI-Controller, and the KeyStep Range all have MIDI connectivity over USB, as well as MIDI x1 Input/x1 Output (x2 MIDI Outputs on the KeyStep Pro). To sync with your external hardware, there are x3 CV Outputs on the KeyStep and KeyStep 37, whereas the KeyStep Pro has a whopping x12.

Choose between the Keystep, Keystep 37 or Keystep Pro and find the right one for you.

For users that need a built-in Drum Sequencer, Pattern Chaining, OLED Screen, Metronome, Project Save, x8 Drum Gate Outputs, x12 CV Outputs, MIDI CC Automation, 16 note Polyphony, 16 Sequencer Pattern Slots per track and 3 Sequencer Playing Modes, check out the Arturia KeyStep Pro.

As with the sequencer, you can adjust swing, gate time and tempo subdivision while your arpeggios are playing. Finally, the LED strip above the keyboard also displays triggered arpeggios in real-time, so you’ll never lose your place.

A sequencer that listens, learns and responds to your style of playing. Experiment with intuitive step-sequencing or live recording, complete with ties and rests, and hear them back instantly. Append your sequence with extra notes, or replace/overdub notes at any point. There are 64 steps at your disposal, with 8-note polyphony per step. Save up to 8 sequences and switch between them on the fly. Change swing, gate time and tempo subdivision, even during playback. Your sequenced notes are shown on the colourful LED strip above the keyboard - sequencing has never been this easy.

Inspiration in the journey
You won’t always find inspiration at the summit. Sometimes it’s in the climb. Sometimes, the magic lies in those accidental moments along the way. Bursts of unexpected musicality, of impulsive improvisations, of melodies forming themselves in front of you. The interplay between KeyStep 37’s inspiring functions results in an immersive experience where ideas blossom. Carve your path, relish the process, and you’ll find the sound you’re looking for.

Energize your voicings with time-based strum effects, select the number of notes per chord and adjust velocity sensitivity - the harder you hit, the more notes you’ll hear.

Easily assign your own CC values to each bank using the panel itself, or via the free MIDI Control Center software. Personalise the way KeyStep 37 communicates with your desktop synths, modular gear and VST instruments

Early days but doing what I bought it for. A couple of things would improve the out of the box experience: a longer USB cable and the 12v supply being included. But so far so good.
