It delivers a soft, muted, and warm tone tailored for delicate, expressive, and cinematic playing. The preset softens the attack of the hammers, replacing the standard bright sound with a smooth, velvety timbre.

Someone said: Pianoteq's Sombre preset trade an upfront sonic character for close, personal warmth. This makes the preset feel like you are sitting alone with the instrument in a quiet room.
Unfortunately, I have a heavy playing style and struggle to play softly.  Still, I hope my demonstration/test, using various chords, provides a good taste of the 'Sombre' preset.
