Ketron GP1 Classic Grand with Stand

The GP1 Classic Grand represents the state of the art of portable digital pianos in terms of sound quality, weight and dimensions.
It has a new and sophisticated sound generation, obtained thanks to a meticulous note-by-note sampling technique and on different dynamic levels, of one of the most famous digital Concert Grand Pianos available on the international market. It is compact and light, making it ideal for Recording Studios, for live performances, for teaching and for use at home. In addition to the sounds of the Grand Piano, the GP1 also has Electric Piano, Vintage, Strings, Pad and Organ sounds, which can be managed in both Split and in Dual Layer mode.
A professional effects processor provides the right settings and the various colours of sound that are suitable for every type of musical requirement.



NSR stands for Natural String Resonance; it is a special technological device used in some Voices of the GP1 (Classic Grand and Bright Grand) for an even more realistic reproduction of the natural resonance of chords and of the sound board of the grand piano. Unlike many other digital pianos, which exploit physical or virtual models to recreate it artificially, the resonance is absolutely natural on the GP1.
You only need to play a few high notes of the Classic Grand and the Bright Grand with the sustain pedal enabled to appreciate this important feature.


The GP1 has 32 different VOICES, which can be accessed directly from the front panel of the instrument.

GP1 Voices

Thanks to the DUAL/SPLIT mode, you can select two different voices simultaneously, to be played over the whole keyboard or in Split mode; in this way, you can assign a sound to the left part of the keyboard and one to the right part.

The GP1 has a powerful EFX section with 16 effects that can be activated via a 16-position switch unit on the front panel of the instrument.


Some of these 16 effects are already assigned to the Voices and set automatically when the GP1 is switched on.
The EFX Value potentiometer is used to control the range of the base effect used in the Voice, modifying its speed, intensity or other parameters on a case-to-case basis.

Keyboard 88 keys weighted.
Polyphony 128 notes.
