Polyphonic pitch detection

Dear Community!

I am looking for a MaxMSP object or any tool which reliably detects pitches of polyphonic music in real-time - particularly played on an acoustic piano - and sends the MIDI code to MaxMSP. Unfortunately, I am using Windows. Therefore, neither antescofo~ nor transcribe~ are available to me, and Melodyne doesn’t work in real-time.
Is there any hope for me to get any tool working on a Windows PC??? Or are there any other solutions? If someone could compile for instance transcribe~ for Windows, I would be happy to pay for this work!
