My tip for the day - learn to use Tempo and Dynamic lanes in Dorico. They will bring the music to life more than buying a “better” sample library.
I have a large collection of Vienna Symphony instruments. VSL is considered to be one of the best libraries but I’ve pretty much stopped using it. The reason is that, to get a good performance, you have to programme in the idiomatic playing styles of every instrument. That takes too long and my objective is to finish an arrangement and produce rehearsal material. NotePerformer lets me do that incredibly quickly and, though it’s nowhere as good as handcrafted VSL, I get no more money for a VSL version than for one created with NotePerformer.
If I’m sending a mock-up to a big pro orchestra, of course I’ll spend the time on all the detailed programming required but I’ve just finished arranging music for a concert performance and the MD and cast were delighted with the rehearsal material I’d sent - thanks to NotePerformer.
