Standard required for computer rendition

[Mal-2]

Simply put, I have questions regarding the performance standard required for a computer-rendered performance to be acceptable. I'm not talking about something produced with sound fonts and a sequencer, I mean mid- to high-end virtual instruments, Cubase, and much hand-massaging of individual parts (often down to specifying vibrato and intonation as pitch bends -- I aim for something approximating 5-limit Just Intonation when it makes sense to do so).

I have no problem offering examples of what I would like to post (along with the scores of my original arrangements, not just rendered performances):

• The Planets (sax sextet with percussion - possibly insanely difficult because of range and circular breathing requirements)
• Pictures At An Exhibition (sax sextet, no percussion)
• Night on Bald Mountain (sax sextet with percussion, no extraordinary technique requirements, totally playable)
• Champagne Galop (brass quintet)

I also have renders posted for which I have not produced scores because I needed recordings, not scores. However, since I initially did them in notation software (as I almost always do), making usable scores and parts is merely tedious, not so much difficult. I won't bother if told that my recordings are not good enough to go up here, since those would be the "reference recordings".

• Toccata and Fugue in D Minor (brass quartet, difficult but playable)
• The Fifth Symphony of Beethoven, and the first movement of the Sixth, for 17-piece wind ensemble (not even particularly difficult).
• The "Nimrod" Variation from Elgar's "Enigma Variations", for 13-piece wind ensemble (woodwind quartet + sax quartet + brass quartet + timpani)
