Although the Modern D is a solid sampled piano, and I use it, the sound is quite flat, not to mention the high notes that don't sound the best. No matter how much you add reverb to it in an attempt to liven it up, nothing significant changes. Many other sampled pianos sound better but have other drawbacks. On the other hand, Pianoteq has its own stamp of sound, it is a playful digital piano, on the recordings you can clearly hear that it has a richer sound than the Modern D piano and it has a dimension in terms of sound depth. Not a recording of an acoustic piano but a modeled expression of it. As such it is better to play and technically closer to an acoustic piano. Personally, I don't mind its sound character, and some models individually please the ears more than others, regardless of the similarities in tone character. If it's modeled, it's no less piano than sampled. It is impossible to draw a black and white conclusion, persuasion is futile. Like paper and the keyboard endures all kinds of typing and words, so it's the same here. I like to think that it's about everyone's desire to somehow grow their digital piano into an acoustic one. Until then, I'll use whatever comes to hand depending on how I feel that day and how my ears are in the mood.
