Dope controller, I got this over a year and a half ago and I still love it, the controls feel nice, nice weight, good resistance, easy to setup and use, I use this with FL studio (Windows 11) and it's great. Setup was easy, downloaded the driver, restart, go into midi devices in FL and enabled it in the bottom window, and that was it. Now everything is assignable. To link something you just right click the thing you want to link and click "link to controller" move or click the part of the controller you want mapped and click accept, DONE. I HIGHLY recommend setting yourself a base save file template with everything mapped the way you like, and back the save file up on your email/cloud/whatever. Now you just open the save file instead of the app and now it opens straight into your favorite experience, accidentally override it? Download it again from your backup.

I've played keys for several years, but always on technically borrowed equipment. This is the first large keyboard I've ever owned, and so far I love it!

Pros:
- Dimensions are PERFECT for me (shoutout to the absolute GODSEND in the reviews who provided accurate dimensions, I'll repeat them: 40¼" x 10" x 2¼" (3" with knobs) or 1023mm x 253mm x 58mm (75mm with knobs), as you can see it slots beautifully onto my desk!
- Love the semi-weighted keys, it hits the balance of feeling sturdy while staying agile
- Mod and pitch wheels feel SUPERB; just the right amount of resistance to aid precision without compromising speed, and the material is just.... Mmmm yes
- Drum pads feel great, perfect material and just the right amount of travel (almost none but just enough for a bit of passive haptic feedback)
- Aftertouch!!! It's not poly, and the range is kinda small (i.e. it goes 0-127 quickly) but definitely usable and better than nothing!
- The lights OOF just gorgeous! My whole aesthetic mostly consists of black body with dark blue lights, and as you can see this fits perfectly. Love it!

Cons:
- Knobs have too much resistance for my taste. They feel great and can be super precise, but forget about any really quick adjustments.
- Button clicks are INSANELY loud. Not sure who in their right mind would put that anywhere but especially on a MUSIC controller where sound (or lack thereof) really matters. Wouldn't want to use them in performances or anywhere near live mics.
- Lights as far as I know are one-way, non programmable. I was hoping this could replace the NanoKontrol 2 I use with MainStage, where each patch can send updates to the button lights and keep them in sync, but this doesn't seem to be the case. Same goes for drum pads, those lights seem to be hard-coded to reflect velocity, in both brightness and color. That's all fine, but seems like something that wouldn't be too hard to add.
- Bootup animation is fun but a bit long... Takes almost 7 seconds every time from powerup to ready. Not awful but not preferable.
- The controller software... Oh boy. What a mess. Didn't work at all on my MacBook Pro (kept crashing when I select preset) and even when it did work on my PC it's still a clunky design. Gets the job done eventually.

Conclusion:
Despite the cons I love this keyboard! Not to mention how (relatively) inexpensive it was! I've only been using it for a couple weeks, so if anything happens I'll update this review. Overall highly recommend, especially for home studio!

This is a really fantastic midi keyboard for the price it's at.

The pads feel great, all of the rotary encoders and buttons feel of quality. The pitch and mod wheels feel absolutely fabulous, they've got a good amount of resistance to them without causing issues of not returning back to where you expect them.

Then there's the keybed. The feeling of this keybed is by far the best I've laid my hands on for
The big issue is that the velocity difference between the white keys and black keys is very, very significant, because the exact same velocity curve is applied to both of them. The black keys aren't treated separately. So, if you play the white keys inbetween the black keys, and press on them at the same leverage point, you'll sort of get the dynamics that you expect (still not perfect)... but that's not how you're supposed to play a keyboard. If you have any training in playing the piano, the velocity difference between the white/black keys will drive you nuts. That's what led to me ultimately returning it, which is sad.

Even with that said, I'm leaving this at 4 stars. Sounds strange for a product I returned, right? Well, it's because it's otherwise THAT great of a keyboard. If you're not classically trained, and if you're not playing instruments where the velocities matter that much, this will do wonders for you.
If you're playing stuff where the velocities are sensitive (pianos, orchestral instruments, percussion), I'd urge you to only give it a try if you're willing to return it if you don't like it.

I want to love this keyboard, maybe someday I'll be able to. If I learned that they fixed the velocity curves so that they black and white keys would respond as you expected them to, I'd buy this keyboard again in a heartbeat.

I've owned this keyboard for over 3 years, and so I thought I'd offer some insight on this controller for anyone on the fence.

First off, do yourself a favor and download the Alesis VI editor so you don't have to deal with the onboard LCD to reprogram your buttons, knobs and keybed. It makes reprogramming every button a breeze. The (free) editor alone is almost worth 5 stars on its own.

PROS:
-Keys feel nice
-Drumpads feel VERY nice - usually keyboards with drum pads usually have a feeling that the drum pads were added as an afterthought. These drum pads, on the other hand, are very responsive and durable. My MPD218 - a dedicated drumpad midi controller - only feels slightly better than these.
Almost every control is reprogrammable on the keyboard within reason. You can't send CC commands from the keybed, but pretty much everything else is fair game. I can have each individual button mapped to different commands. For instance, button 1 might be a momentary CC, button 2 a program change, button 3, on/off CC, etc. Same with the drum pads, which can send CC commands and notes. In Ableton, the keyboard has the appropriate LED feedback.
-Preset slots make using this keyboard for different uses/setups a breeze. Again, DOWNLOAD THE ALESIS VI EDITOR to make your life easy for modifying presets.
-Reliable - this keyboard has been with me through 2 moves, a couple drops, and 3 years. Hasn't missed a beat .
- It even has a 5 pin midi out port if you want to use it to control other 5 pin midi devices.

CONS:
- Some of the knobs have a slight jitter that appeared about a year ago. For example, say I turn knob 1 to have a CC value of 120. The keyboard might send 119, 120, 121, 120, etc. all in succession, several messages a second. Not the biggest deal in the world as it hold the value within 1 or 2 CC values, but kind of annoying when you want to set a knob and be done with it. I also don't like the constant moving on certain knobs as it can cause a little more strain on my computer if I'm already pushing it to the limits. That being said, setting each knob at 0 or 127 fixes the issue so it's not a constant thing when I have the midi controller plugged in.

- This is really nitpicky one, but I'm unable to control the LED feedback on the controller no matter what I've tried. Sending midi out messages to the computer doesn't seem to do anything visually with the LEDs. Again, this is very nitpicky, and the LED feedback is automatic with Ableton, but I like more custom control. And one of the DAWs I use, Gig Performer from Deskew, doesn't automatically incorporate the LED feedback on this keyboard.

Overall, this is a buy and I highly recommend this keyboard. It was a steal back when I purchased in March 2019, and even now the price is a little higher, it's still a great value. Durable, reliable, customizable. Good on Alesis for the quality product.

This keyboard has so many features I was looking for for the type of music I create. Its a solid build, doesn't feel cheap and plasticky, has a fair amount of weight to it. The only qualm I can think of is that the knobs could be infinite knobs so you wouldn't have to go back and forth finding where your parameter is before controlling it. Setup on Logic Pro is time consuming but once it's done it works flawlessly. I think that is more an issue with Logic than with the keyboard in particular. If you're looking for a good controller with pads, knobs, semi weighted keys and a ton of totally assignable buttons you absolutely won't be disappointed!
