Best tool to synthesize jazz band from piano score?

[unix1980]

I'd like to take piano sheet music and score and synthesize it to sound like a jazz band (horns, drums, etc.). What is the best tool to accomplish this? IOW, the input is piano sheet music (which I expect to re-enter manually, not via MIDI), and the output is an audio track that sounds as close to a real jazz band as possible. Does Ubuntustudio have the tools I need?

Thanks!
