Yeah it's mostly Orkester and the Reason soundbank key-switch instruments. I'm trying to convince my mother into getting me the Miroslav Gold bundle for Christmas, which is on sale for $99 right now. Fingers crossed! I can't wait to have better sounds. I am aware of sound fonts but I really just want Miroslav.
One huge problem I ran into with the strings is there are so many piercing frequencies from the stock sounds that I had to cut that it made the strings weak and thin. Tried to compensate by rolling off a lot of highs.
