I’m just re-visiting a Suite for Wind Band that I wrote in 2006. I penned it in Sibelius 5 and have never heard a live performance. I downloaded ‘Note Performer’ demo a few days ago and apart from a few things I’ll have to tidy up (mainly percussion parts) Note Performer is doing a pretty good job of interpreting the Dorico score I did sometime when Dorico Version 1 first appeared. I think the crux to the question ‘Note Performer or sample libraries’ ultimately depends on what you’re working towards. If it’s a pitching job for a film or TV ad, I’ve found that directors and producers are people with limited musical imaginations where soundtracks are involved. It only needs the instrumentation to be off, and they won’t be able to hear the great melody you’ve assigned to the heroine and hear the canonic treatment of it just as she saves the day. They might just hear a naff synth sound. You might have been better leaving the idea just as a piano track and telling them it will be scored for orchestra. If you get the gig, depending on the ‘readies’, you might be able to employ an assistant to do the orchestral mock-ups, before recording it with live players. I think we’re some way off being able to reproduce even 50% of what’s doable in a DAW, simply because mixing and placing of instruments in a sound-field is as much a part of the whole thing as the notes and the genre.
