I purchased this to use the MIDI with a GNX4 pedal board. This unit did not come with a power supply: I used a standard 9v expression pedal power supply and the unit would not even turn on. The only way this unit turns on is when I plug it in via USB. Not getting any sound out of it, regardless of how it's connected. Edit buttons don't work. Very disappointing!

I purchased this because I trust Monoprice and I needed a smaller keyboard for when I travel. The construction might feel a little cheap, it's either that or I'm just so used to my other (main full sized) keyboard, which is a pretty high quality, that this one just feels different. I traveled a lot over the summer and brought this with me an was very pleased with it when I got adjusted to using it. Overall, I am happy with the price and the product. This is basically the cheapest 25-key on the market and mine has held up really well. No problems with it so far. It's small, cheap, decent quality, and it gets the job done. I'm happy with it. Monoprice has yet to let me down!

The size is great for your desk top and the price is unbeatable. Plug and play and you can do fun stuff with Garage Band or the MIDI software of you choice.

No frills keyboard that does what I wanted. Octave keys on the side are very helpful. Keys are a little too springy but nothing bad.

Overall very happy.

simple and cheap, it gets the job done. unable to find drivers to get full functionality, but the keyboard is fine under standard win 10 drivers.

Incredible value for money, it packs a lot of functionality as long as you're expert enough to use those functions in your DAW.

Bought this midi keyboard for a friend, it was on sale and i couldn't turn it down. I thought this would be a great introduction to a midi keyboard for him, and it has been. Some users have reported that lower keys don't report 100% velocity, i have found this to be untrue for the one i got (i wouldn't have minded anyway). Tested in both Ableton Live 9 and Fl Studio 12. Then again, i was mashing them keys pretty hard. Build quality feels pretty good for a budget Midi Keyboard. Monoprice blew this out of the water. Great job guys!

I was excited for this keyboard as it looked like exactly what I wanted. Unfortunately, I received a bad unit. On first inspection, it appeared to work just fine (recognized by my computer and software, sent MIDI data, etc), but when I tried to access some of the setup functions (in particular, reassigning the control knobs) I ran into trouble. Essentially, in settings edit mode the keys were not behaving according to the labels on the keyboard, but were instead acting like they belonged to the bigger version of the keyboard. However, because there are fewer keys on this one, the edit mode is unusable. My working assumption is that it received the circuit board for the larger keyboard and the customer service rep agreed with me. Got a replacement, but it has exactly the same issue, so I am returning it for a refund.

Now, the good thing about this is that it has a nice full-size keyboard with decent action, the knobs, slider, and bend/modulation dials all move smoothly and consistently. It feels like a budget keyboard, but a solid budget keyboard. Also, I dig the retro black with red LED display aesthetic. I only wished it worked properly. In the future I will definitely consider purchasing the larger version of the keyboard, but it doesn't fit my space at the moment.

Right now, I'd stay away from this product, but if Monoprice gets the quality control sorted out, it would be a solid 4 or 5 stars.

On the positive side, Monoprice gets a big thumbs up for their customer service and I'm off to leave some positive reviews for other items that I got in the same shipment.

As described,fast delivery,good price,nice Midi Controller ,works great,Thanks.

A couple quirks that may only apply to my model, but without them, it's a fantastic product, well worth the money!

PROS: This really does work well. It feels nice to play, the keys are the correct keyboard size, the pressure can feel a little... multiplied sometimes(?). The sliders feel great to move, the knobs feel nice to turn, overall, it's a quality product, and I do recommend it - IF other copies didn't have the same problems.

CONS: The volume control slider does now send data to the computer... I have an M-Audio Keystation 88 es MIDI keyboard, too, and the volume slider works fine to the PC, but this little one's volume data doesn't pass onto the PC. I know it's doing something in the keyboard because the slider value shows up on the number screen on the keyboard itself. So, that doesn't work unless I'm missing something?

When I very first used it the top C key would sometimes not play when pressed. Only a short few times... I haven't noticed it since the first time I used it.
