Feature:
There aren't as many features as a workstation or something, but for a stage piano/midi controller, the features are very good. The ribbons are awesome as a midi controller, much more fun to use than a wheel.

Quality:
This keyboard is extremely durable and incredibly well made. I've heard of plenty of people who have spilled liquids in their SP88s and dropped them and not had any problems. The casing is made of metal, so I think it will last a very long time.

Value:
This is a VERY good buy and a better board than almost anything in its price range.

Desirability:
The stylish purple casing is very attractive and sleek, though that's really about it as far as the aesthetic appeal goes. The screen isn't that incredible, but it works well, and that's the important thing.

Sound:
Most people would probably buy a stage piano for the piano sounds, and if that's what you want, that's what you get. There's not an incredible amount of variety, but the piano sounds are fantastic and the other sounds are pretty good too.

Ease of Use:
The SP88 is very intuitive and very easy to play out of the box. The manual is well-written, so if you have any problems, you'll be able to figure them out quickly.

Support:
I haven't had to deal with customer support since I haven't had any real problems with the keyboard, but based on the strength of the manual, I'd assume that they're doing a good job helping their customers.

Overall:
Overall, this is a fantastic light-weight stage piano and the best in its class. I plan on keeping this for a long time and don't foresee any problems with it. I would highly recommend this keyboard to anyone looking for a good semi-weighted stage piano or midi controller. The durability is incredible, so if you want to travel with your keyboard, that ought to cement this keyboard as your best option. The purple casing is very cool and the piano sounds are very good. You have no reason to not buy one of these at this price, so g ahead and get one now!

Feature:
It comes with the pedal (among with the dc.) It so cool to have it comming with the pedal! (and its a good black thick pedal). Now besides the accesories that may include, I dont think features are the strong of any dig.piano, i mean what could you possibly expect? to sample? to sequence? to fly directly to the stage? But I do have a features critic on this product, and it is about those fancy-wannabe ribbons. They seem just a waiste of about 10 cm of the width! well saying this may be a little too much since they do work on midi controlling, but it wouldnt hurt them too much either if they would aloud all of the organs and (why not) the eps to be affected by the ribbons! or to make one of the ribbons change the tune! like any regular ribbon.

Quality:
Sturdy as a tank. And I like to add I really like the feel of the keys, it is a very little bit light compared to a pianos´feel but its very well made,the lower section is heavier than the upper, nice detail!

Value:
I believe its a good inversion for the quality, but for my personal economy it was not cheap at all!

Desirability:
Big, heavy sturdy and black. Its investor on a stage, good presence.

Sound:
Beatifully mellower than a korg´s, vivaciously brighter than a yamaha´s and just much realistic than a roland´s, the piano sound in this product is the best one I´ve herd in the digital piano world. Of couse, there are better sounds in more advanced dig.pianos but these are much more expensive, so I am writing my comparision between the products of the same level (or the product´s competence, if you like) I personally heared and played identical products of casio, yamaha, alesis, roland,gem and korg, but when I heard the kurz piano I said "this is the one, this works for me!" Is a real gig mosnter! and that explains it about all. I´ve never did a recording, thought, I imagine is at least as good as it is live. As a negative point I would say I would like if the "grand piano" were more sensitive, it has a low expressioness, the "stage piano" on the other hand is very sensitive but is not as thick as the grand piano, so some chords just dont stay sounding for much long. Other point is about the other sound but piano. The one or two ep´s and one or two rhodes are good, the rest is not very usable. And i find only one organ to be of use,but would it hurt them to make all the organs and ep´s sensitive? (some are not :( ). The strings are usable (when i say usable i mean they are not superb, or a sound revelation to the ears, but they are not lame either), and we know strings can be lame! The pads are nice too. But I personally were never insterested in many features or sounds but a good decent piano, and boy this baby has one! One piano on stage. I give a 10, because my paramethers are the products you could get by the same price and in terms of a piano sound this is the best!

Ease of Use:
Really simple and graphic interface when passing to one sound to another, sence each couple of sound has his own button (couple because they come two sounds per button, just press again and get the other spund). General basic settings, such as transposing,changing the tune or the sensitivity or adding much or less level of reverb is not very complicated. -Now I really want to add this obvservation, i didnt know if it belongs here or in "features", I think here is ok. I read somewhere the word "lightweight" as one of this piano´s good things. L I E !!! BIG FAT LIE! This got to be THE most heavy dig.piano of all! The manual says 30 lbs, I dont know were they come up with that number because this baby weights at lest the double!-

Support:
I never needed support. Only once I asked about the ribbons by email because I thought they dindt work and they answered me just hours later.

Overall:
Weak points of this piano are the weight (little too heavy!) the unpractical ribbons, the grand piano that´s not very sensitive and the ep´s and organs that are almost lame and not usable. But it is light enough to carry (for a couple of minutes,lol) and there are some others patches that sound good, especially the strings and pads. Again the strong of this product are the piano sounds, which are lovely! Obviously no one (should) expect to get a real piano sound from any digital product, but this is more than close enough! The "stage piano" is my favourite, I would like to be as thick as the "grand piano" but the diference is bearly considerable. I wolus like it too if the decay were more slow, if the sound kept sounding a bit longer, especially in piano or pianissimo play, that CAN be accomplished with the "warm piano" but since its some kind of mix of a piano with some ep it doesnt have the clarity of a piano patch, but it sounds great anyway. In overall, the great piano sound overcomes any flaw on this product, since its the main feature and it is the best among his competitors.

The only downfall is the overall sustain isn't long enough, even when using a sustain pedal. The hugh upside is it only weighs 30lbs. and has incredible onboard sounds. This unit is perfect for the begginer as well as the stage pro who uses various midi sound modules and effects!! Believe me, I have had many keyboards such as: Roland and Yamaha, and for the price, weight and overall performance I, and you, can't beat the Kurzweil SP 88 or the 88x. Enjoy!!

Reliable, reasonably simple, and with sounds to die for, mix this with a decent sound module, and you have the perfect live line up. The piano sounds are studio-worthy, even if the others (strings, Eps, and organs) are only OK. The action is a little loud for quiet home tickling, but it's on stage where this incredible beauty comes alive.

When I started looking for a new midi controller, I had a few different keyboards to choose from. After checking out the "nothing but midi" boards like FATAR, I decided to give the SP88 a try. Knowing that it was the same sound bank as my MicroPiano made me a bit hesitant, but all that changed once I had my hands on the semi-weighted 88 key axe. I am real happy with this purchase. The sounds are sharp, the keyboard response is great, and I can easily move from internal sounds to my Voce Micro B2 sounds with one click (32 presets for internal/32 for midi). If you're looking for a great piano/controller at a great price, then you owe it to yourself to check out the Kurzweil SP88. You won't be sorry!

Feature:
Great piano sounds, lame tonewheel organ and electric piano sounds. Very light action.

Quality:
The keyboard itself has performed flawlessly on tons of gigs. However, I feel that Kurzweil should provide a more substantial power supply. The included one, which has an extremely thin, brittle cord, started to short out in a memorial service and nearly lost me $200.00!

Value:
Very inexpensive, nice sounding keyboard.

Desirability:
About as "Sexy" as a good fingernail clipper, but it does the job.

Sound:
I use it almost exclusively for the piano sound. And I am very happy with that. There have been a few occasions when I would like to have a Rhodes or B3 sound, and it's best to stay away from those on this instrument.

Overall:
Very inexpensive, lightweight, good sounding keyboard. if you're a real piano player you won't like the action, far too springy and light. But if you have to play background music in a hotel, tyou can schlep your entire rig in one trip.

Feature:
The included sustain pedal is nice. It has good control of pedal and other MIDI controls but could definately be embellished upon.

Quality:
The teeny LCD screen has some weird film on it.

Value:
I use this as a MIDI controller for a seperate rack-mount sound system and it works great. Its lightweight and easy to transport which is what I bought it for--and what I received!

Desirability:
I bought it because it is sleeker and more professional looking than other lightweight MIDI controllers.

Sound:
The samples are terrible. This, thankfully, is not what I bought or use the keyboard for.

For the price, an 88 key controller WITH Kurzweil pianos & organs? Yeah!!!
Sounds are great, good dynamic range on the keys.

I have 2 issues with this unit.
1) The color of the text on the panel. Kurzweil, what were you thinking!? You CANNOT read it unless it's under a 100W+ bulb! It makes changes on stage very difficult.

2) The sandpaper texture of the ribbon controllers. This absolutely sucks. It's like trying to drag your finger across the top of a skateboard.

If you can tolerate that, you've got yourself a great unit at a low price.

Considering there are other products for controllers that have NO sounds at all, and cost the same and more..... you can't go wrong with the SP 88. It feels good and the 32 sounds on board are nice. My only wish were for it to be expandable and upgradeable. I guess I could always buy the PC rack module :) But it would have been nice to have more sounds on board.

Feature:
The ribbons in the place of modulation wheels is stupid and impractical, and only functions with 3 or 4 of the sounds on the thing.

Quality:
Seems to be put together well but I've only had it for a couple of months and haven't used it on any gigs.

Value:
You get what you pay for. Spend a bit more money and get something good. Don't waste your time with this.

Desirability:
blah

Sound:
I am very unimpressed with the sounds on this keyboard. The grand piano is mediocre and that is probably the best sound on the board. There isn't one usable electric piano sound out of the 10. My old Roland XP10 has better ones. In addition there are these stupid ribbons in the place of modulation wheels that serve almost no purpose, They only function with a few of the sounds and are awkward to use. Kurzweil told me that they are for midi applications, which would be great if I could get the midi to function.

Support:
I contacted kurzweil about the midi not functioning at all. They told me to run a cable from the in on the keyboard to the out on the keyboard, and if I got a signal then there was nothing wrong with their keyboard. That doesn't help me considering every other midi instrument i've plugged in to my computer works perfectly instantly, without any tweaking. So I would say they were pretty unhelpful. They did respond to my email quickly however.

Overall:
I'm going to get rid of this as fast as possible and buy a roland.
