Disklavier

I have been using Van Basco's software for 5 years or so. Great, free
product. I just bought a new mac desktop and would like to play my
midi files on it, rather than the pc. Apparently Van Basco does not
have a player for Mac. I have not been able to find one using Google
but I believe that there must be something comparable to Van Basco's,
even if is not free.  Anyone running on a Mac out there????

Thanks in advance.
