Rock solid, smooth interface, great price
Rock solid device, capable of much beyond what I need. Used for feeding out MIDI to an old Yamaha keyboard as well as a Behringer CAT synthesizer. Interfaces with Mac and Windows MIDI stuff no problem. Very nicely built, solid, not shaky or cheap, really smooth action on the keys and very playable. The ONLY goofy thing, this is very minor and this is pointed out in videos I've seen on the unit, is that the ribbons for the pitch and modulation will DEFINITELY be scraped or rubbed by the left hand during use, by accident. Just the nature of the design, if it gets too aggravating you can put a piece of cardboard over that area. Otherwise this is an amazing unit with expansive capabilities for what is relatively speaking a super low price. ... show more

By far the best midi keyboard I've ever used.
This thing is incredible! The build quality is killer. Thick plastic on a steel plated bottom gives it the feel and weight of high end equipment. The keys legitimately feel like real piano keys and the knobs/buttons have a good feel/resistance. Let me tell you how good it feels going from a 25 to 37 keys. No more fiddling with the octave buttons every time you use it. The height of the keyboard is perfect if you plan to keep it on your desktop too. It has a built in sequencer, arpeggiator, chord progressor and transport controls that works with any DAW. Tons of ports and clock functions! It will connect and play nice with almost anything you throw at it. Also: It has a power switch. Those still exist and I'm here for it. Don't wast your time on those cheapo "mini" keyboards. They feel bad, are too tall to sit on your desk comfortably and don't have the necessary ports should you choose to play with synths, samplers and grooveboxes . Spend the extra pennies to get what you really want. ... show more

Great for beginners, even has tools to play the music for you!
This model compared to the original Keystep is well worth the extra price for untalented or still learning musicians, I'm guessing I'm both, who want to get into electronic music making. The chord mode and strum can add some great effects with simple singular note presses, and the scale you set makes sure you can't hit a wrong note! Just get it, it's built SOLID, feels great to use, and if you go from computer to proper synths, the various jacks on the back are all there to make it a great controller outside of just being a usb device. ... show more

Great well rounded MIDI Keyboard for beginners and pros
I will preface with : This is my first MIDI keyboard. I have been producing music (non professionally) for over 3 years now. I have always used my keyboard as my MIDI input device. I know basic-intermediate music theory and can mess around pretty well on the piano. I did NOT REALIZE how useful it would be to have a MIDI keyboard during my production sessions. I love it! Here are my Pro's and Con's. Keep in mind these are through the eyes of a beginner when it comes to any kind of major hardware. Pros: Compact size and very light 37 Keys is the perfect amount for me Arpeggiator is really nice and pretty intuitive Keys have a pretty nice weight Chord function is fun and the strum feature helps add a lot of depth and character to simple progressions Design is very pleasing to look at. Love the touch pitch and mod wheel on the sides. PRICE!!! Cons: Spacing between keys can make it hard to play wider chords. (fingers get stuck between black keys) A little challenging to get the hang of the sequencer and use it efficiently. Overall, amazing product at an amazing price. I love the device and will be using it for a VERY long time routinely during all of my production sessions. From the perspective of a beginner, I would wholeheartedly recommend this MIDI keyboard to all! ... show more

Fun tool for DAWS or hardware synth with MIDI connection
Love it.

I love Arturia
I have three midi controllers: the MiniLab 3, the KeyLab 61, and the KeyStep 37. And I got them in that order. All white. I love Arturia. The KeyLab 61 is obviously really nice like you'd expect but it is a big boy. This one, however – the KeyStep 37 mk 1 – is my favorite of the three. I really like the analog knobs (which unfortunately they've replaced with a screen in the mk 2 that just came out), the metal chassis, and the form factor. It's exactly what I was looking for. ... show more

Arturia you must do better especially in the holiday season
I won't even dignify Arturia with one star except I must give it 1, considering that you must register inorder to get the downloads and unlock codes for the software. The support is terrible, the website is broken in multiple places. No reason for a website that doesn't work or an IT department that doesn't fix it in a timely fasion. Problems with website include but are not limited to: You can't register the product links to registration busted, and registration for busted, or wouldn't accept codes at are on the bottom of device and on card in box.
