The Kurzweil SP7 – Stage Piano
Bringing the amazing sound quality and features of our SP series within reach of more musicians than ever before.


Authentic Timbre Synthesis Technology

The SP7 is designed upon our new synthesis platform A.T.S.T. and marks a new era in Kurzweil technology. Built around our custom semiconductor, A.T.S.T. features high fidelity audio, streamlined sound programming and boasts near seamless velocity layer transitions.

256 Voices of Polyphony!

Serious polyphony to power your most demanding performances!

2 GB of Factory Sounds!

The SP7 offers 512 multi presets organized into 13 categories and features our German “D” 9 ft. Concert Grand derived from the K2700.

Piano Focussed

Fueled by the German 9′ grand piano samples found in our flagship K2700 workstation, the SP7 A.T.S.T. engine provides significant advances in realism through support of higher resolution audio, smooth velocity transitions and a 2x oversampling filter.

Details Matter

The SP7 pianos are further enhanced by the use of both string and pedal resonance modeling, envelope/velocity controlled key-off samples as well as half-damper* pedaling, together delivering a heightened piano performance experience (* half-damper pedal sold separately).

A Multitude of FX

21 effect algorithms are available to enhance the SP7 rich sound, including reverb, BPM-synced delay, chorus, flange, compression, various distortion types, rotary speaker, tremolo, wah-wah and eq.


88-Note Hammer-Action Keyboard

Discover the SP7 fully-weighted hammer-action, ideally balanced for feel and playability, serving a variety of playing styles. Choose between two chassis color options: black and white.

16-Zone Multi Controller Mode

The SP7 offers 16 performance zones for creating your own sonic split/layer combinations along with a host of customizable controllers.

Hybrid Arpeggiators

The SP7 Hybrid-Arpeggiator combines both a step-sequencer and note-arpeggiator. This original twist on the classic arpeggiator design is capable of generating endless possible musical phrases.

Stay in Tune and Harmonize

Auto-stabilize the pitch of the mic input as well as adjust the signal’s vibrato and legato qualities. Further process your vocals and automatically generate up to 4-part harmonies in real-time as well generate as vocoder-like effects.


Color Touch Display

Navigate the SP7 via its elegant 480 x 282 pixel, high resolution, 4.3″ color LCD touch screen.

USB Audio Interface

The 2-in-2 out 24 bit/48 kHz audio interface easily connects to your Mac/PC via USB. Mix with the various effects on the SP7 to create new sounds. Loopback functionality further expands the production capabilities.

Take Control

Express yourself and enhance your performances using the SP7’s programmable pitch/mod joystick, 8 knobs, 8 buttons, 2 switch pedal inputs and continuous control pedal input. Customize the colors of the various front panel knobs and buttons to suit your style and application.

Easy Access Transpose Controls
