Is it cheating? Of course! Any editing, alteration of the sound, tempo, etc is cheating . . . especially yourself. I know this probably sounds like something you were told about cheating in math class, but it's true. If you're a practicing musician you really should master your techniques the good old-fashioned way. Once you start on that road, where does it stop? First you speed it up a little, then edit a few parts together, then why not just program the sounds in, then just scan the music into a note-recognition software program and push play.
I think we all agree doing stuff like this is big-time cheating, and we would not tolerate it here (though it could be impossible to detect).
However, cutting out a couple of flubs, restarts, or page turns from an otherwise satisfactory recording, or adding reverb or equalizing, are perfectly acceptable IMNSVPHO. I believe many people do this here, and we know it's done in many professional recordings too.
"Honesty," in the applicable sense, however, means complying with the rules of the Society. For example, if you edit "heavily," as I have done on much of my WTC, then your bio should indicate that. Mine does; but many others don't. And it's very hard, indeed, impossible to PROVE what's going on.
That doesn't trouble me too much, however. Bad music is BAD no matter how it comes into being. Good music is GOOD, again, no matter how it comes into existence. Much of what appears at the Society is good, honest piano playing, with much to recommend it regardless of technical deficiencies. That sort of music is more important than concert-perfect or recording-perfect music (two entirely different species), because all great interpretation and composition rests on the efforts of thousands of journeyman and women pianists who, regardless of talent (an entirely subjective concept), practise, practise, and practise.
