There is a programme from neuraton called Audioscore. I have the lite version which I really haven't used as it's only monophonic and doesn't record from a keyboard. I'm more of a pencil and paper at the piano type and then into Sibelius for my scores.
According to the website, the ultimate version of audioscore can transcribe from a keyboard and produce a notated score. It's fairly pricey but there is a trial you can download to see if it's what you are looking for.
Here is the link. All the best.
