Authentic Timbre Synthesis Technology

The SP7 Grand 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 Gigabytes of Factory Sounds!

The SP7 Grand 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 Grand 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 Grand 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 Grand’s 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 TP/110 key action, featuring the latest technology from Fatar, the world’s leading piano-keybed manufacturer. The action is ideally balanced for feel and playability, serving a variety of playing styles.


16-Zone Multi Controller Mode

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


Hybrid Arpeggiators

The SP7 Grand 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.
