El SP4-7 representa una de las pocas opciones que hay en el mercado de teclados compactos de 76 teclas semi-contrapesadas.
Si bien los sonidos tienen ya una cierta edad, en mezcla resultan bien.
VENTAJAS:
-Con 76 teclas se puede tocar prácticamente cualquier partitura para piano y con una anchura de 110 cm (gracias a la situación de las ruedas de pitch y modulación encima) es posible situarlo en espacios reducidos.
-La pulsación es muy agradable con sensación de contrapeso, pero ligero. No como algunos teclados que presentándose como "semi-weighted", tan solo tienen un muelle de mayor dureza que la de los típicos "syntes".
-La construcción es de un acabado profesional metálico.
-Opción de situar hasta 4 sonidos "layered".
-Se pueden fácilmente cargar sonidos del PC3.
-Grandes capacidades midi cómo controlador.
-El precio actual resulta muy atractivo para un teclado profesional de estas características.
La compra a través de Amazon Premium, cómo siempre ha sido excelente y representa una garantía cómo no he encontrado en ningún otro vendedor.

3.0 de un máximo de 5 estrellas Got one year of good service out of it... 30 de septiembre de 2011

The SP4-7 is just 24lbs, in a truly compact design. Nevertheless, it offers 76 semi-weighted, full sized keys that feel very responsive. 128 available sounds, with another 128 user banks, are carefully chosen and programmed to power through a bar, club date or wedding gig. It's simple and easy to use, with split or layer on the fly. Instant access to the pre-programmed, customized effects for each sound sample.

What's not so great? Compared to competing keyboards like the Korg Krome or Yamaha MOX, there just aren't nearly as many sound choices. Though the sounds are "borrowed" from Kurzweil's flagship PC3 series, they're compressed, dithered versions so the smaller processor and system software of the SP4 can handle them. This stripping down shows mostly in acoustic sounds like piano and guitar; they seem dated and less nuanced compared to what's offered by major manufacturers these days. Yes, there are instant controls for effects and timbre, but for many sounds they are about as basic as they come. Two or three sliders that might control individual volume for split and layer would also have been welcome.

The worst two problems with this keyboard are: Obsolescence and Reliability. Kurzweil has already begun selling its PC3LE series, a lighter, less involved version of the PC3 line, effectively overshadowing the audio appeal of this model.
A little more than a year after I bought the Kurzweil, out of nowhere, my SP4-7 began having serious electrical problems. Lights and display were on, but the sound would stop and start, right on stage, accompanied by sizzling and buzzing noises. Took it twice to a repair shop, they're still not sure what's wrong with it--might be a microscopic short in the circuit board or a crack in the keyboard bed somewhere. I traded the SP4-7 in two weeks ago for a Roland Jupiter 50.

The SP-4 gets an A for ease of use, overall sound, great feeling keyboard bed and portability, a C- for lack of more modern design and obvious shortcuts, and D for reliability.

4.0 de un máximo de 5 estrellas Nice sequel to the SP76 and superior to the SP2. 10 de enero de 2011
Por Samuel C. - Publicado en Amazon.com

[3/17/16): I'm sure I've worn out a dozen piano cases in my lifetime. Since I'm so lightweight-conscious, I usually go for the canvas bags, and few are good for more than 20-25 jobs before they began to tear apart. So I finally invested 3 times more in the Nord Red Bag that's made for a keyboard with similar dimensions to the Kurz SP4-76. It's a snug but perfect fit (room for only a adapter, pedal and spare cable), and it's proven indestructible (knock on wood). For anyone who hopes to be able to carry this piano over their shoulder or in their left hand, I give a hearty endorsement to the Nord "cloth-like" piano case. It almost makes me want to try out one or two of their instruments.]

This is the most recent addition to the Kurzweil family. I've owned practically all of them (some stolen or broken, most sold in exchange for something better--from weight and size to the number and quality of sounds to more readable instruction manuals (dream on). The Japanese-made K1000 (circa 1990) remains my favorite, but I can no longer find one that's "fit and ready." Which brings us to the SP4:

Pros:

1. The size and weight are just right for the traveling (and tiring) week-end warrior--sufficiently compact to fit across the smallest car's back seat (thanks in part to the placement of the modulation and pitch-variation wheels above, rather than at the left end of, the keyboard).

2. The number of sounds. 4 times as many presets as the SP76.

3. The ability to split and layer. Increasingly, I'm required to be the "bass player" on the job, a role not suited for the preceding SP76.

Cons:

1. No ability to layer a ride cymbal onto any of the bass sounds. This is the SP (i.e. player's, performer's) model as opposed to the PC line (great for the programmer or orchestrator). So what is Kurzweil thinking when they throw in vocal sounds (an embarrassment to play in public) and overlook the crucial (and actually useful) layered ride cymbal?

2. The usual Kurzweil learning curve (and be prepared for Kurzweil's tendency to come up with new operating systems and upgrades, some of them a challenge even for a dealer to download and install). The instruction manual is guaranteed to keep the neophyte up nights, whereas the previous SP76 was instantly playable. Immediately I wanted to dial up a touch response that was less soft and soggy than the factory setting. Try the sparse index--nothing under "touch," "sensitivity," "keys," not even "parameters" or "global" (which is where you'll find the adjustment). And from all indications, customer support is worse, not better.

Neutrals:

Supposedly the piano and other sounds are based on the new and "amazing" PC3. Frankly, the piano sounds of the PC1 and PC2 strike me as no less sterling than those of the PC3.

Previously, the Kurz SP76 was the handiest of all professional-level performer's keyboards, so small that I could carry it to a job strapped over a shoulder with an amp in one hand. Its limitation was the absence of any splits, making it necessary to have another keyboard or tone generator on the job for left-hand bass. Moreover, the keyboard was simply time-consuming and frustrating to MIDI with another device. The Kurzweil SP2 appeared to be the solution, but it frankly proved an unexciting instrument to play. Moreover, it's a rather cumbersome axe, twice as heavy as the SP76, and prone to misfire when set-ups are switched in the middle of a beat. Finally, I wasn't able to get a bright, ringing ride cymbal sound layered to the bass--a feature that has vanished or diminished since my K1000 from 20 years ago, when Kurzweils were still made in Japan (they were bought out by the giant Korean piano maker, Young Chang).

Except for the added cost (the SP76 would occasionally be as low as $500), the SP4-7 is far closer than any other current Kurzweil to the original SP76 in size and weight, and it offers the advantage of splits and layering, plus more and better sounds (e.g. vibes), and a full bank's worth of 128 presets (the SP2 had 64; the SP76, 32). Despite the inevitable difficulty of programming even Kurzweil's most basic keyboard, the additional preset sounds are a major improvement. That feature alone makes me wish I'd waited longer before trading in my previous SP76.

[It passed the first test--a 2-hour dance job, played after an hour or two of reading the instructions and saving several useful sounds. The vibes on this new SP model make me realize how much they were missed on the previous SP76. The next big test will be a job requiring that I split the keyboard and play acoustic/electric bass. A WARNING to those who haven't purchased a Kurzweil recently: I'm unable to get my 2 recent Kurzweils' audio jacks to accept a conventional, high-quality instrument cable (Monster) with monaural jacks. Only "balanced" (stereo, or TRS) cables "push" all the way in. As sturdy as they look, the CBI balanced cables sold by Amazon have been a disappointment--shorting out, stripping, etc. I hope the "economy" Hosa balanced cables remain in stock.]
would connect with my PC1 and PC4-76.]

If you are looking for a live performance keyboard that combines lightweight, 73 keys, quality piano and a broad range of other sounds, I haven't seen anything I like better, particularly in the price range. Only knock I have is that not all sounds have the same volume, which means you may need to adjust the volume setting during live performances in order to keep a consistent volume for your audience.

If you are looking for a good, lightweight case, the Nord 73 gig bag gits the Kurzweil like it was made for it - perfect glove fit and it's an excellent case.

It is super easy to split. I start the split for bass at D# below middle C and then I program about 5 different sounds for my right hand. The one problem that I've had is that it's difficult to find repair technicians. I recommend this keyboard for any professional who wants something very practical.
