Propellerhead's "Radical Piano" RE is a hybrid modeled and sampled, but it's nowhere near the quality of Pianoteq. One thing I do like is that you can route audio in the piano to excite the strings for an interesting effect (or for more realistic scenarios like a piano in the same room as a jazz band, the instruments would excite corresponding strings etc). It would be interesting for the Pianoteq RE to do a similar function, or other features that would take advantage of what Reason is capable of.

Anyone else have any thoughts?
