I know the topic was here already, but there are some things I like to bring on top again (driven by some recent digital recordings), in order to hopefully start a fruitful discussion about that again. Background: The thing is, one can by listening of a recording very often detect whether it is coming from a real piano or a digital piano. However, if it comes from a digital piano it is not so that it is difficult to check whether the file was from real playing or not - instead it is impossible. Because it is no acoustical difference whether the take is recorded as midi file and played back through the same keyboard (or other sources) to record it as audio file or recorded directly as audio file. If it is recorded as midi file it is an pretty easy thing to manipulate indefinitely. In fact it is very easy to remove flaws, play it back faster or make a run smooth, or change dynamics. One can get a flawless masterpiece by editing, and this I consider as a dangerous temptation, because it is easy. A recording based on a midi file is what I would call a fake if it is not clearly mentioned as a recording produced that way. Since midi based recordings are not allowed here, to fully right, nobody who likes to have his digital recordings hosted here, will acknowledge that. That's a problem, isnt' it? To make it clear - I will not accuse the honesty digital piano submitters here, however! On the other side also audio takes from a real piano can be manipulated, e.g. they can be cutted. But at least the pianist shows that he/she was able to play it once in the manner it is played back, even if it was not in a row a complete piece. Professional recordings are also often produced in that manner, so it seems. However midi based recordings are by far more vulnerable for manipulation, I think. Proposal: My suggestion is that in future, only acoustical recordings from a real piano are allowed here. The most of recordings submitted are real piano recordings anyway. The rules are of course up to Robert in first rank, but let me please state this proposal. What with those who don't have a real piano: So there is only a problem with the small percentage of submitters who don't have an acoustic piano and have only a digital one. It may be different in different countries - but at least in Germany there is always a school in the near, or a church or an assembly room with a grand or at least an upright piano. I know from own experience, that at least if one proposes to spent a tuning, one gets open doors for using it. And - larger rooms or churches or school auditoriums are often much better from the acoustics as at home. Also, during nights they are very quiet. So hopefully, this would solve the problem with recording on a real piano. What remains is the need for a recording equipment. I think there are easy to use and affordable mp3 recorders which deliver sufficient quality. What do you think about that?
