Hi Steffan,
Is the issue with the release (or just overlap?) on some notes down to you or the player/samples? Because your phrasing is so different to the recording, I am assuming that it was an interpretive decision on your part, or perhaps you used a different edition to the recording!
Sadly though, for me, whatever samples ( or interpretation) you used for the allegro theme at around 1'08", they do not supply the clarity required for the music and as a result, are quite off-putting. The sustain was uneven in places and as mentioned above, the overlap in places was too noticeable and not really acceptable from a listening point of view. The timbre too was an issue for me, especially for a classical piece.
Sorry I couldn't be more positive on this but accept that you are re-learning to a certain extent too. My own personal jury is out on Synchron at present and am waiting for a definitive demo that'll make me take the plunge. I've heard good shorts and pizz, but that is only half the story.....
