Cool bit of kit! I like it.
The Roland AIRA Compact J6 Chord Synth is a little box of magic for anyone who loves crafting synth sounds without needing a full-sized keyboard (but you CAN connect one via MIDI if you want to of course). It takes the power of Roland’s legendary synths and squeezes it into something you can toss in a backpack. Right out of the box, though small, it feels solid. Small but not flimsy, with buttons that have a satisfying click and a layout that makes sense even if you are just messing around for the first time. The built-in chord sequencer is where this thing really shines. You do not have to be a theory expert to create lush, evolving progressions. Just pick a key, choose a chord type, and let the J6 do its thing. Sound-wise, it delivers a classic Roland warmth and depth. The Juno-inspired synth engine brings fat basses, dreamy pads, and plucky leads that sit beautifully in a mix. It is not just about playing chords either. You can tweak filters, modulation, and effects to sculpt your sound and add movement. There is even a built-in arpeggiator that adds instant groove to anything you play. The battery life is decent, and it plays well with other gear thanks to MIDI and sync options. Whether you are jamming on the go, laying down ideas in a DAW (as I often do), or integrating it into a live setup, it fits in effortlessly. If there is a downside, it is that the small interface can feel a little cramped when making deeper edits, but I suppose that is to be expected with a compact unit like this. Overall, the J6 is a fun and inspiring little synth that packs a serious punch. Whether you are a beginner looking for an easy way into synthesis or a pro wanting a tiny portable tool for quick ideas, this one is a winner.

Excellent modern pocket sized take on a classic synth.
Having had a Roland SH09 since new (yes I’m old) I am constantly astounded by the synths available today for not much money.The fact that I can stick this in a coat pocket with some headphones and create music anywhere is frankly amazing.The sounds are terrific and the controls are easy to grasp(especially if you have basic grasp of how synths work-but it’s just as much fun just twiddling knobs).The only danger with theses modern synths is the price -it’s too easy to justify buying another!

First step into DAWless
I was initially looking for a drum machine, but took a chance on a sampler instead. It’s very portable, very powerful, and very fun. takes a while to learn, maybe a month with purposeful practice. The built in battery and the IO are great, means I can play around with it away from a computer then record into Ableton when I want to refine a little tune.

It’s a good device, but not really suitable for beginners. I went with the Akai MPK Mini 4
I’d be happy to say something good or bad, but I’m not a professional. It’s clearly a high-quality synthesizer from a well-known brand. However, I wouldn’t choose it as a first synthesizer, as it’s quite specific. I bought the Akai MPK IV instead — that’s something a beginner should really start with.

Wow
I love this J6 from Roland. It is so portable you can literally be creative anywhere with a set of headphones and a good 3-4 hour internal battery life. The controls are very easy to use and work out before reading the instructions. For somebody who isn't very musically talented this device makes me sound like a music legend. So easy to create chord progressions with plenty of space to save your own progression. There are some useful chord progressions already programmed in which really get your creativity going. Switch of the chords function and you have a keyboard to create a tune. The arpegiator and its vast range of styles only adds another creative twist. What I really love is that I can plug it into my computer and the functionality of the J6 transfers straight to your DAW though MIDI so any sample can be used with this devices functionality. Even better, it will also work as an audio input so you can use the built in sounds along with all the adjustable to put some legendary sounds into your production. Love it!

Nice portable mini sequencer
Part of Roland's range of mini synths, the J-6 is primarily a 64 step sequencer capable of single note and chord sequences. Comes with 64 built in synth sound pre-sets, small LED display screen, 64 programmable patterns (inc. some demo patterns). The sound can be tweaked with filters, delay and reverb. Power comes from the built-in Lithium rechargeable battery or through the USB port (charging/data lead is included). Can easily be linked to the other Aira compacts in the range (T-8 drum machine, E-4 voice tweaker and S-1 synth) via 3.5mm TRS MIDI sockets, or to a computer (works with Ableton Live etc). The unit also has an extensive pre-programmed set of chords as well as style and variation settings that can be used in your sequences. Note: Headphones/ear buds or an amp is required to hear any sounds and the full manual has to be downloaded from the Roland Website (highly advisable). I think this little synth is great fun, either solo or when used with other Aira compact units and it is small enough to be taken anywhere.

Very robotic sounding
Fun to play with but it is just a gimmick and doesn’t negate the need for an autotune plugin if you’re as bad a singing in tune as I am.

A 606 and a 303 for a decent price
Good, slightly tweakable Roland drum sounds, but sadly not that many. Just 606 type sounds with additional clap. 303 acid bass sounds as you would expect. Has decent effects, but no song mode. Maximum 32 step sequences. Knobs are a bit fiddly, but Thonk sell trimmer toppers that can make them a bit taller and fatter. Some functions require menu diving. Side chain compression and effects don’t work on external audio in, unfortunately. It is rechargeable so it doesn’t eat batteries. A bit expensive at original price but good value now at around £150.

I brought this for a present for a musician. They are really impressed with the product and made so many songs and tracks from it

エフェクトも充実しているし、MIDIでのコントロールだけでなく、Sync信号にも対応しているし、なかなかいい音が出せます。 また、オリジナルのシーケンスを64個も記憶していつでも呼び出せるので、いろいろなパターンを切り替えながらならせるのが楽しいです。 少し残念なのは、モニター用のスピーカーが内蔵されていないため、外付けもしくはヘッドホンが必須なところですね。温室が少々悪くても手軽に音を出せる方が絶対に楽しいです。 あと、オッシュレータにディチューンをかけられないのもちょっと残念。まあ、ここはコーラスで代用すればなんとかなるにはなるのですが、やはり限界があるので、ディチューンは欲しかったです。 でも総合的にみて とてもコンパクトで楽しめる1台だと思います。

Great sounding device. i use it for quick chord patterns to use under video work

Trés bel appareil, demande un poil de prise en main quand même…mais avec 1h de lecture de mode d'emploi on est dedans. Le reste s’apprend petit à petit je pense. Et pour les fonction plus complexe cela demande encore plus de temps… logique MAis en 2h on peut créer des boucles vraiment intéressantes, et l'echantillonage est hyper rigolo. Je l'ai acheter pour un enfant de 8 ans… c'est un peu jeune… mais il prend plaisir. C4est un process a 2 avec un adulte dans ce cas. Les effets sont aussi trés intéressant et donne une dimension infini et intuitive qui marche bien avec les enfants.
