I am happily using Note Performer for my string quartets and it does a mighty fine job in general. But I find it a bit artificial for the string sounds in very slow passages. Hence I was looking at Halion bundled with Dorico. After exploring a bit I used the Solo Violin samples etc, but I have to say the quartet ends up sounding like a harmonium. It’s pretty terrible - I feel that can’t be right.
Consequently I either need to know what sort of stupidities I may be doing and what to look out for, or what a really good solo string quartet instrument library is to use with Dorico. I am after a very realistic quartet sound.
