In spite of all criticism, I took up the challenge and "fabricated" a Prelude for Piano and Violin.
I don't have the Strad yet and used to GPO Strad instead. The piano is the Steinberg Grand2. And I did this in three hours after one hour of preparing the score fit for Garritan. Originally this is a Prelude for solo piano.
Prelude for Piano and GPO Stradivari
As I am not having any other more complicated scores for violin I have to do with my own composition (1988).
