Feature:
The most useful features on this synth are the presence of so many, many sounds. That is the main reason I bought it. Also, the synthesizer capability is a main reason. I like to have control over sounds, like to adjust them to my needs, and then store them in a user memory. The possibility of connection a pc with the To Host cable is a fantastic function! Many manufacturers seem to be developing this Keyboard-PC interface function, and would very much encourage their efforts. The least useful thing would be the Memory Card; if I play live, I make sure I store my sounds in a user memory, and for all other playing situations I use my computer. There is actually nothing more I can wish for on this synth... It's so complete!

Quality:
The product is made of good material, doesn't feel cheap, has a solid look and feel. They have sliders instead of knobs which in my opinion are better because knobs may easily break off while turning them. Rolands always have been very reliable, and are excellent choices for playing live, at home, or in a studio. It seems this baby will surely last a 15 years if properly handled.

Value:
This product gives you the most value for your money. The most sounds, expandable functionality, PC connection, etc. Everything about this is worth it.

Desirability:
I is a fantastic product to own, not only for it's professional look and feel, but mainly for the endless sea of available sounds.

Sound:
I think the sound has a professional touch with many elements from the JV-1080 and JV-2080 modules. The sound quality is very good. It has a lot of usable sounds that can be used in all sorts of music styles. The sound responds really good when playing. Many sounds are good usable in writing my songs. Because of their large quantity I often use the Patch Category Finder to quickly find a specific sound. Sounds are very well adjustable. It's a synthesizer ! It has a lot of options to adjust sounds that can be achieved by scrolling through the menus. It is a good thing that they have the assignable sliders to immediately adjust a sound while playing live for example, and it is also possible to save your customed sound in a user memory. All these things are so practical. Really a must in today's versatile music instruments.

Support:
I haven't had to deal with Roland's customer support, so no comment about that. I rate them a 6. Not bad, not good.

Overall:
I expect to be satisfied at least 5 years with it. For now I can discover the many sounds and fiddle with them. It is a great thing that it can be expanded with 2 expansionboards. A thing that will keep it fun for a long time.

I just buy it last week. It has very good feature. The keys are great. my only problem is i'm not good in technicalities because this is my first time to have a keyboard synthesizer but I played some. Like Yamaha and Technics. For just a week I can do what i want not like the other keyboards maybe because this is my first time playing a great keyboard. One problem is the user manual. I think the manual is for advance user. I can manage some of it but I really need help for those who are experienced.

It is the best synth ever built...
I owned an xp50 then an xp60 and this one is way over both of them.The sounds are excellent and thousands of them,It sounds pro at a tiny price.You will love the orchestral board it is amazing,so is the session and the techno.It is pro,you must buy it.

I've owned my XP-30 for almost 2 years now, and have been impressed with it from day one. It interacts easily with popular applications and is an absolute breeze to set up and start playing with. The sample editor is weak and a great many of the patches are useless, but the vast majority of them will suffice for any style of music. An additional two expansion bays on top of the three built-in cards makes this the absolute best bang for the buck for those getting started.

it sounds great, it plays great
editing is easy, the expansion boards rules,
the strings & drumkits i just love them can't live without them :)
man,it's a roland what you expect.

no one metioned the size .. for me its compact .. a friend of mine recently bought another brand digital piano .. but when he heard this XP30 .. he was very impressed.The only thing he thought it needed was 88 keys.
I only really use it for computer music with a copy of Evolution Sound studio as my sequencer .. & it works a treat.Its more flexible than my old SY35 in the midi dept.The keys feel nice & i think i will probably keep it for a while.Its got a lot of usable sounds.
Oh .. one last thing.The sliders are recordable too.This makes it ideal for those "tangerine dream " tracks. F A B

I've just got mine, as a synth without a sequencer its fantastic. The sounds are spectacular and if you're a nut on techicalities you'll be impressed, but if you're someone who just likes to make music wit hflawlesss sounds and ease of use you won't find anything as good in this price reange, a sequencer would be good, but this stands alone as an actual instument.

Great sounds and lots of them! The only bad thing is the manual, I use it mostly for sequencing (with a computer) and there was plenty of trail and error in the beginning. But you just can't beat this great sounds + nice keyboard action + low price-combination.

It needs more analog outputs (only has one stereo pair) Some great sounds for every taste. Good solid build, no worries at gigs. Its easy to navagate quickly (with a bit of practice, so many sounds!)

Exelent product

The only thing lacking is an onboard sequencer. Other than that there are some great sounds--and lots of them--all for around a thousand bucks. This is a solid keyboard and a great deal.
