Review: 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.
Review: 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.

### ⭐⭐⭐⭐⭐ Great for beginners, even has tools to play the music for you!
*by J***N on June 10, 2022*

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.
