Review: Even just playing a scale sounds awful as it will sound like you are slamming down on some of the keys ... - I was highly optimistic when I purchased this keyboard. I've now owned it for about six months, and I would have given it a 4 star rating initially but now its drawback has become a real pain: As other users have mentioned, the velocity pressure sensitivity varies wildly between keys. Do not purchase this if you are intending on recording melodic parts with any kind of expressive control. Even just playing a scale sounds awful as it will sound like you are slamming down on some of the keys and barely touching others. The software allows for some calibration, but even doing the MAXIMUM level of compensation for the sensitivity difference does not cut it. Now for the positive: besides this velocity problem, it looks amazing, feels amazing to play (drums are less of an issue velocity-wise) and at least has the illusion of being a quality piece of gear. The reason why I'm giving this unit 1 star is because it sells itself for the expressive freedom and versatility it has. If it were just another cheapo micro midi key unit I wouldn't hold it to this standard, but the reason why I paid twice as much for this as I could have for one of those was it's purported expressive "control." it's basically unusable in a serious way. If it weren't for that one issue I would have given it 5 stars, but by the looks of it the company has made no effort to fix or even respond to this issue.
Review: Melodies: Improved. Lights: Awesome. The future is now. - ...Im taking a quick break from playing, because I feel compelled to let producers / musicians know. The Future: This keyboard is revolutionary. Im the picky type about keybeds, the action & feel of the keys when Im playing synths. My midi boards must have very playable, expressive feel and high build quality. I dont like clanky, cheap, noisy distracting keys of most brands. Compositions: Very responsive playing, the layout allows for playing quicker, thus laying ideas down faster. 1st thing I noticed when playing on this, my melodies come out quicker and honestly better than before. Its a new and inspiring way of playing, its look, a refreshing change from centuries of traditional black and ivory. My theory is, the pad layout and velocity allow my brain to react quicker, like drum style, to where Im going next. It just feels so much quicker to get ideas out versus regular keys. Aesthetics: The lights are beautiful. In my dim studio, each note lights my fingertips with each touch, as if the pad light & sound are an extension of your hand. An amazing experience. Ive been playing keyboards since the digital 80s, the QuNexus has so much charm and fun factor in its aesthetics and ease of playability. Solo or chords, the compact size and pad layout didnt negatively effect my playing at all, it feels more like my brain, fingers and the pads are one. The build is solid, has a non-slip, no fingerprints, slightly rubber touch that feels right. Improvements: The octave shift key blinks when set - or +, at a rate that conflicts with the bpm of your song project. Not a big deal, its all mental, but can be distracting when youre locked into a session. Id like to see a 37 key version, to have more range playing bass solo with left, and chords/melodies on the right. I can do this on the 25, but I would like to go an octave deeper for the bass, but that's nothing but a quick midi nudge in my daw, done. Final Word: Great for travel or studio. USB, MIDI, CV, they left no electronic musician out of the loop, everyone can join in. Almost speechless about the emotional connection I feel when playing this. It feels futuristic, has a Tron / Blade Runner personality, like a tech toy, but its no gimmick. Playing on this feels awesome. Its an interactive playing performance Ive never felt before. I love it. I demo'd keys and playing feel of a few other compact boards @GC, but no dice. I decided to wait, and Im glad I did. The QuNexus arrival has changed my entire perspective, I honestly can't go back to full size synth keys after playing on this. Congrats Mr. McMillen & Co. This is the best compact midi keyboard.

## Questions & Answers

**Q: Can this keyboard show scales?**
A: It's not built in (say like the Komplete Kontrol keyboards).  The lights are addressable by software IIRC, so if you had software that could trigger the lights for a scale, that would work, but not nearly as convenient as a keyboard with that built in.

**Q: Has anyone actually used this with any android devices? if so, which? how was the experience? what apps did you use?  what adapter cable did you use?**
A: Hey Adam-Thanks for your interest in the QuNexus.I am not aware of it being used with Android.The manual doesn't really talk about Android at all.It Has instructions for Windows/OSX as well as iPads.That being said I'm sure it is possible one way or another just not well documented.Thanks!

**Q: chord**
A: It will play chords.  I don't think it has a limit on number of keys down, so you're limited by your synth's polyphone.It uses a micro usb cord to connect to USB on the left-hand side (along with some CV jacks, which I don't use), and the midi connection is on the right with a mini usb connection (To their midi breakout box) and another CV on the right.

**Q: What kind of warranty comes with this product?**
A: Warranty info is at the KMI website.

### ⭐⭐⭐⭐ Great portability, Great interactivity, could still be even better
*by J***T on April 30, 2014*

This is great controller for computer music instruments like drums, guitar, even flute and others. Works great with GarageBand. But as a pianist I cannot say it replaces a good hammer action keyboard for piano playing. Velocity sensitivity can be inconsistant. I was quite surprised when it arrived at how small it is. The pitch bend is used by rocking keys up and down, left and right would have felt more natural. The Roli Seaboard offers this, but it is much more expensive & less portable. Also, Garageband 10 supports the Logic Remote on iPad, which provides nearly just as good an experience, at zero cost. I find myself using the Logic Remote app more than this controller nowadays becuase it works to well with GarageBand. But this controller does provide a unique level of control with aftertouch & pitch bend etc. Great fun to play with, very portable, not so expensive, give it a try..
