There is nothing like a real piano, this is so important in our western music that is impossible to be completely satisfied with synths or samplers.
But we have some standard in electronic music with "not so real" piano emulations that have become familiar and fashion with musician and listeners, think of Roland U20/220 and P330, Korg M1, all Kurzweil, some EMAX and AKAY s1000 etc. Now MDA sets a new standard, i have recognized it in some late dance hits. It sounds so good, surprisingly for it's 1,2 meg (in mac), that i have completely dropped my big, hundreds meg, halion/akay pianos. As in all good real istruments emulation the samples are not the only aspect to care, the fundamental thing is to reproduce the dynamic response and the articulation of the source and MDApiano has got them. The user interface could be more nice and clear, but i do not care too much, with these few controls it is easy to learn. MDApiano could be a great value also if MDA decides to sell it instead of giving it free!!!
