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.
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.
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.
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.
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.
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.
