VSTValidator™
VSTValidator™ Key Features:
- The plugin is designed for violin, viola, cello, and double-bass;

VSTValidator™ reviews a midi track, indicates instrumentation mistakes, and provides simple but effective hints. The user experience has been made extremely simple and user-friendly.
Just choose an instrument, click the check Instrumentation button, and get the matrix view where Feasible events are colored green, Inconvenient events are colored yellow, and Impossible events are colored red.
The matrix view below indicates an issue on 3rd and 4th beats. By selecting the midi event in red, you will see the error details including the hint.

Hint: Try C2 and G3 instead
