It's rather difficult to write a 1000 character (required) critique for a simple one sound VST but I liked these strings so much that I'm going to try.
I found this sound pleasantly full bodied. Also the notes come up to full strength very quickly, which was important for a fast paced song I'm tweaking that has strings in the lower octaves.
Occasionally I like to just improv on the keyboard for ideas and this is my number one pick for a sound to do so with.
As a one sound VST, there really isn't an interface, and of course it's a "one trick pony" and that's fine. It doesn't need a manual. It doesn't have nor need any presets. I haven't needed customer support. Is it a good value for the money? Time is also Money, and with that said, it's still a great value for the time/money. It has been perfectly stable.
Rach's Prelude in C# minor sounds very good on it. Messing around in C# sounds real good in general. The high pitched notes sound very smooth as opposed to piercing.
