Enhanced Compact MIDI Control

The Arturia KeyStep 37 offers a fresh approach to MIDI control and sequencing. While many modern musicians have become accustomed to using their keyboard controller for basic note input only and doing all sequencing and arranging in their DAW, there are many situations where hardware control over sequencing, arpeggiation, and chord and scale modes offers a distinct advantage. That’s where the KeyStep 37 comes in. Arturia has packed this compact controller with advanced features that will supercharge your music creation process. Beyond its 37-note keyboard, knobs, buttons, and LED screen, there’s a lot of high tech under the hood that doesn’t readily meet the eye.

Packed with advanced features

The KeyStep 37’s velocity-sensitive keybed has aftertouch — something you typically see only on high-ticket controllers — as well as RGB LED feedback. Take a look at the rear panel and you’ll see control-voltage (CV) pitch, gate, and modulation connections for integration with modular synth setups. Then there’s the 64-step polyphonic sequencer with eight patterns, an 8-mode arpeggiator with new random modes, and a unique Chord mode with 12 voicings. You’ll appreciate the capacitive pitch and mod strips, which are easy to play but don’t have moving parts to collect dust or get damaged. Add in 5-pin MIDI DIN I/O as well as USB-MIDI and USB bus power, and it all adds up to a formidable, attractive, compact, and roadworthy package designed for the modern musician and producer on-the-go.

Highly playable keyboard

While 37 synth-weighted mini keys obviously won’t satisfy serious concert pianists, the KeyStep 37 will hit the sweet spot for many musicians looking for playability in a compact package. Three octaves is an expansive enough range to accommodate limited two-handed playing and melodic lines that incorporate octave displacement without having to hit the octave shift buttons (which are conveniently located, in any event). And Arturia made sure the keybed is highly playable. The piano-style keys are a bit larger, with wider spacing than most minis on the market, and assuming you have average-sized hands, they are satisfying to play and feel great to dig into.

Interactive music creation

The KeyStep 37’s advanced features offer an interactive and uniquely creative way to write, arrange, and produce your music. At Sweetwater, we’re particularly impressed with Arturia’s unique, enhanced Chord mode, which lets you choose from 12 chord types and a selection of strum effects, and spread the voices out into complex, velocity-sensitive parts that sound and respond like a real stringed instrument. Get exotic with Scale mode, where you can map out KeyStep’s 3-octave keyboard range with a scale of your choosing. Don’t worry, you can’t hit a wrong note — any key you play will automatically quantize to the closest note in your selected scale.

Sophisticated creative control

KeyStep 37 gives you sophisticated control over the inner workings of your hardware and software. 16 MIDI CC parameters across four switchable banks let you adjust your settings in real time using KeyStep’s four new rotary controllers. Connect your hardware synths with MIDI I/O. Take command over your VST instruments with MIDI over USB. Integrate your modular gear using the CV pitch, gate, and mod ports. KeyStep’s onboard clock connectivity keeps your entire rig in sync. To get you up and running right out of the box, the KeyStep 37 includes Ableton Live Lite and the MIDI Control Center app for effortless MIDI mapping or your Mac or PC. Take creative control over your MIDI setup with the Arturia KeyStep 37.

Instent Love

I've been using the Keystep 32 Black Edition for quite a while, which has been awesome. I love that keyboard. The things I love about it are...

1. Nice fit and finish, for a keyboard in its price range and size, its the best quality no doubt.
2. MIDI in & out, plus USB plus CV, which makes it compatible with all gear.
3. The arpeggiator, which is great for making electronica.
4. The sequencer that provides more ways of being creative.
5. Aftertouch for more expressive play, and opens up all the possibilities of your synths, both hardware, and software.
8. Expression pedal jack. Not all keyboards in that price range have one.

So when I saw that the Keystep 37 came out, I knew I had to have it right away. It has all the things the 32 key version has plus +++

6. 5 additional keys, a welcomed upgrade foo show.
7. Chord mode and Scale mode, which makes being creative with chords super easy. It's like having Captian Keys but in hardware instead of software. Where you use your ears instead of your mouse.
8. LCD screen, so you know your tempo and it provides other parameter feedbacks as well.
9. An on/off rocker switch, so you can turn the keyboard off when you aren't using it without having to pull a plug!
10. It's white. And it looks great, if you are thinking you need to wait for the Black Edition, don't waste your time being silly. This keyboard looks sharp AF, even if the rest of your gear is black. It looks amazing so who cares.

Cons, there are no cons. But if Arturia came out with a blend of the Keystep 37, and had a baby with Keylab Mk II, and maybe called it the Key Lab-Step, I'd buy it in a heart beat.

Also, if you own the MC-707, getting this keyboard is a no brainer to marry this up with it. I'm also planning on adding the Mother 32 to this rig as soon as I have the cash.

Great MIDI Controller for the Money

Only scratched the surface of this Keystep37's potential and I am liking it alot already. Using it Dawless to control a 35 year old synth and a 40 year old drum machine via Midi cable it is working great. Interested to see what it can do when I finally get a computer. Blue stauts lights really make computer free setup easy and green key lights make altering Arpeggios and sequences extremely easy for someone like me with little piano or keyboard chops. Probably should give it 5 stars. maybe once I have thoroughly tested all the features out I will .

Excellent Companion to Other Arturia Products

This keyboard is invaluable to me. I have an abnormally small left hand (from birth) and using this keyboard and its smaller keys along with my KeyLab 49 enables to me to play full keyboard parts. The two keyboards work seamlessly as a single instrument in my DAW. Arturia makes updates and configuration easy, and the installation is downright painless. This is a very nice product.
Rated 5/5

Excellent Controller!

Got to complement my Native Instruments S88 MKII. The size of this is perfect! Fits on a desk, small enough to be portable. Just enough features to keep you busy, but not so many to be overwhelming. It has been reliable for me and the connectivity has been what I needed. Definitely recommend this if you are looking for a controller.
Rated 5/5

Couldn't be easier.

I have only glanced at the documentation but the product is so intuitive to use at the onset.
This particular model is tailored to my situation. e.g. limited desk space, i own pre-USB MIDI gear and the keyboards don't have the convenience of rotary knobs to address real-time patch adjustment s. These concerns have been addressed with the Arturia Keystep 37.
