Kurzweil is well known for producing professional-level keyboards with stellar sound quality, and as the successor to their bestselling SP76, the SP4-7 76-Key Stage Piano has a lot to live up to. Fortunately, it delivers. It packs superior sound pallet and customizable effects into a lightweight, compact instrument that’s perfect for any gigging musician.

Slim Fit

At 3.4” high, 11.4” deep, and 43.6” wide, the SP4-7 is an elegantly slender stage piano with a conveniently small footprint that allows it to fit on any stage or in any vehicle. Furthermore, at just 24 lbs., its incredibly light weight makes it easy to load in, saving your strength for the show.

Playability

As a stage keyboard, it’s important that the SP4-7 not only have a solid feel, but also be playable for the entire length of any set. Its semi-weighted keyboard is the perfect mix, giving musicians a solid feel in its resistance while keeping the keys light enough that fatigue doesn’t hinder the performance.

The easily-customized splits and layers bring even more appeal to its live playability. Up to four internal or external MIDI control zones can be created, each with customizable key ranges.

Accessible Sound Banks

The SP4-7 offers convenient access to all of its features using a simple layout that makes it easy to control every aspect of your play. Its 128 factory sounds are accessible through two banks, each with eight groups, and each group has eight presets. Its setups are laid out in the same way, with one bank holding its 64 factory-set splits and layers, and the other ready for customized setups of your own.

Control Your Sound

The sound customization features are all contained in one section of the layout, making it easy to alter all five parameters. Dozens of high-quality effects chains, including smooth delays, deep distortion, pristine reverbs, and real amp simulations all map their most relevant parameters to the function selector button and a single knob. It’s easy to alter your sound on the fly, and it’s much more convenient than having to remember various slider settings.

Broad Range

The 128 world-class factory sounds that are included with the SP4-7 are a featured selection of voices from their PC3 line, and they include a good balance of instruments with plenty of piano and electric piano sounds. There’s a good variety of orchestral sounds as well, and more voices of all kinds are downloadable from Kurzweil’s website.

Exceptional Voice

Kurzweil is famous the world over for its incredible sounds. The rich textures of the piano voices stand well on their own, but have the power for huge sound that can accompany even the heaviest material. The electric pianos are also exceptionally emulated, the analog synths reflect some of the most acclaimed sounds of the instrument’s history, and the clavs feature an incredible level of detail that help them perfectly recreate the feel of the instruments they represent.

Conclusion

The Kurzweil SP4-7 is a professional-level stage piano with powerful potential at an affordable price. Kurzweil is known far and wide for impeccably deep and detailed sound characteristics, and the included effects bring even more character and sophistication to every voice. It’s an ideal option for the gigging musician with the flexibility to make it a great writing instrument, and anyone considering a new investment in their career should certainly give this stage piano a look.

    This keyboard worked for a little over a year for me. Then it randomly started to cut the sound on and off and made buzzing noises. No more Kurzweil for me.

    I downsized from a heavier keyboard to this one and couldn’t be happier. I am pleased I can carry this to gigs easily and all in one trip from the car. I like the sound and feel of these keys. It’s super versatile with midi and usb ports, stereo and headphone lines, and sustain and cc pedal jacks. I wish it was easier to program though, you have to stay calm, lol. Once that’s done though it is easy to get patches and splits when you’re performing. Overall I would recommend this to anyone that needs a lightweight good quality keyboard.

    This is the only brand on the market that doesn’t have a line for the hobbyist. I believe that says something about the quality of this brand. I love the sound of the piano and the fact that there are many additional sounds loaded in this piano. I particularly love the strings sounds.

    This is for a pro only; it’s too expensive and has too many features to make it practical for an absolute beginner. But if you are serious about your craft you cannot go wrong with this piano. I love that it has the split layer and that it is easy to split. I usually program 4 or so sounds for one hand. The only downside is that I had a small issue last month and it took me a while to locate a qualified repairman.
