oops
To state, anything in this recording would be synthezised is sheer technical nonsens. Each single note you hear is recorded from a high quality real grand piano with such care, pianos rarly are recorded.
So what you hear is technically a recording as every other recording you are used to hear.
I only listened to the first one
So...fix this, and maybe this project can be interesting to listen to. Otherwise, perhaps this system of yours can only really work on pieces that demonstrate more of the percussive capabilities of the piano, as is more commonly found in the 20th/21st century repertoire.
If you are interested or not - is your own problem. I have interest enough for about 200 hits daily on my page and several of my recordings especially of romantic music has been already chosen as sound examples even from academic institiutions mainly occupied with music.
Meanwhile i can perhaps imagine a bit what you told about the first piece for someone who like you presumably dont know it, it's still a pity that you seem to judge for the most part (the other pieces) recordings you never heard. Allow me not having that much respect nor interest in this kind of musical judgement.
There is no need to know a specific piece when you know the musical genre very well. I have heard enough waltzes (more than enough, and certainly don't need Andre Rieu) to know that the first one does not sound like a waltz.Out of curiousity (so no, I'm not about to have a full-blown argument with you about what a waltz should be like - I just want to know what you think here), do tell me: do you really think it sounds like a waltz? If so (and I expect you to say it does), do tell me what makes it sound like a waltz.
