I think it will take some time before you use this mighty new machine of yours to the full in your improvisation. You could probably afford to cut loose and risk expanding your range of touch because this new piano can certainly handle it.
Of interest to me was the sudden limping 3/4 phrase, which I would have felt an urge to work to death, and further on there was a very attractive sequence of chords under a romantic melody which I would have liked to hear again. Overall interesting though.
