Back when I was learning how to read a score, meaning to play each written note in the violin, I made a small windows app that displays a random sequence of notes in the 1st and 2nd positions.
You can make it quicker or slower, and it also shows you after a few seconds the name of the note and the string in which it should be played in the given position.
The goal is to keep playing the notes until you can do it quickly enough to play a musical piece at its correct tempo. It aides you in memorizing the basic behaviors of playing in the violin.
Download and unzip from here (for Windows only). No need to install, just run the executable keeping the folder structure.
