Topic: Inquire to pianoteq developer about a K2 piano.
I like a K2 piano that is introduced in 5 versions. By the way, there is that find newly using these days. Bass part feels that is not natural if although differs according to situation, change sets and hears sound by headphone. (--- that something seems to crumble...) Curiously, do not feel well by speaker. What is cause of this phenomenon?
