Ketron GP1 - Digital Piano with NSR Technology

Ketron GP1 is an instrument that sets the standards in the world of portable digital pianos. Thanks to advanced note‑by‑note sampling, it delivers a sound that delights with its naturalness and depth. This model is designed for musicians who do not want to compromise on the quality of an acoustic piano while still valuing portability. Its compact dimensions and relatively low weight make the GP1 an ideal companion for both live performances and home studio sessions. It is not just an instrument, but a complete workstation with a rich array of features.

Product Features

The main advantage of the model is a fully weighted 88‑key keyboard that faithfully reproduces the feel of an acoustic piano. The device supports 128‑voice polyphony, eliminating the risk of note drop‑outs during dynamic playing. The 32‑voice set covers a wide range of tones, from classic piano, through electric instruments, to organs and strings. The key technology is NSR (Natural String Resonance), which in specific piano voices simulates the physical vibration of strings, adding authenticity to the sound. The EFX effects section allows quick adjustment of tone color to the acoustic environment.

Professional Possibilities for Your Creativity

Choosing the Ketron GP1 gives you a tool that does not limit your musical imagination. NSR technology is not just a marketing slogan but a real difference in sound. When you activate the sustain pedal on the Classic Grand or Bright Grand voices, you hear a natural resonant response that in other digital pianos is only mathematically simulated. This makes even long chords sound rich and spacious. The DSP effects section with 16 selector positions gives you full control over the sound space. You can choose between Chorus, Phaser, Flanger, Delay or Tremolo, and even add overdrive to your solo parts. The ability to switch between Dual and Split modes allows you to play two different instruments simultaneously, which is indispensable during solo performances where one musician must replace the entire band. Transposing the pitch (Transposer) by +/- 24 semitones lets you quickly adapt to a vocalist without changing fingering. All these functions are intuitively controlled from the front panel, which is crucial in a dynamic stage situation.
