Yes, I've midi-edited these. Although I've played all the WTC over the years (started piano at 5, and I'm 67 now), it would be disingenuous of me to pretend that I'm doing anything other than producing, by hook or crook, a recording that satisfies me personally, and in my case, that definitely rules out the live home recording approach. With the advent of Yamaha's most recent piano player systems, more and more high end recording studios are using the technology. It is cheaper, easier, and way more precise than editing with multiple takes and audio splicing. This represents a sea-change in the industry. We all know that unless explicitly denied ALL modern classical recordings are edited, some quite heavily. Now pianists have the option of editing their performances using MIDI. I'm told that it's ALREADY the norm in many classical piano recording studios. Remember, we're not talking about "MIDI" in the usual sense, but a Steinway D, typically, equipped with the latest piano replaying technology, which is now so completely accurate that the original performance cannot be in any way distinguished from the replayed performance. The original and the replay are for all intents and purposes identical. Therefore, it is obvious that using MIDI to "correct" errors a studio recording is a much cheaper and more accurate way to do post performance editing. I don't know for a fact whether the technology has, at this point, trespassed the sphere of classical piano recordings. But there's no way of knowing, really, unless someone "confesses," so to speak.So, from my point of view, we have essentially 2 types of recording: LIVE recordings which are truly "authentic" in the sense that the pianist is using his hands and fingers and NOTHING ELSE; and NON-LIVE recordings, where not only are minor technical mistakes corrected but also entire conceptions of a piece can be fundamentally altered. The latter has always been the case, I think, even with the relatively innocent technique of audio splicing. Take Hewitt's WTC (there are 2 recordings); I've heard Hewitt play the entire cycle twice, and the live performances are completely unlike her studio recordings. That's not a bad thing at all. It's just to say that retakes and editing, big or small, can fundamentally alter an interpretation. For some listeners this distinction matters. For others it does not. The MIDI edited or audio spliced/multiple retake studio recording attempts to get the listener as close as possible to what the pianist IDEALLY thinks a good interpretation should consist of. We are peering into the performer's mind, not necessarily into the operation of her hands and fingers! (Hands and fingers alone may not convey the performer's concept of the piece.) The concert hall is (or certainly CAN be) something very different, calling attention arguably to audience/artist communication and spontaneity, not to a perfected conception of the music. Gould famously argued that the former--the interpretation in the performer's mind perfected by heavy editing if necessary--was what mattered. The drama of live performance was not his bag. BOTH live and recorded/edited are equally valid and interesting from my standpoint. Covid has been a real downer for me, because I live for live classical concerts. My point is that as far as studio recordings are concerned, I think we have to acknowledge that the game is changing. I wouldn't be at all surprised if ALL studio recordings of classical repertoire eventually succumb to ex post facto MIDI editing. When that happens, for better or worse, the floodgates will open. The sharp distinction that pianists (especially classically trained pianists) like to draw between a) music that is made with the hands and fingers and b) music that is made sitting in front of a computer monitor may become perilously weak.
Midi or any sequencing is not an improvement over real recordings, you tried to convince us years ago of that. Shall we debate it again? Round... what would it be... like 5. Juxtapose a sequenced recording to a real one and we will see how much superior 100% unedited human playing with fingers only on a real piano keyboard is.
