I'm Canadian now living in the US, and an amateur violin player, both traditional and classical. Professionally, I'm an engineer (EE,ME) and computer programmer but have also studied business (MBA). After much research, the unique basis of instrument tone and playability has been discovered and mastered. It is none of the suppositions that have been made in the past, but rather a kind of soliton surface acoustic wave that has gone unnoticed. By configuring this, ANY violin can be transformed to have Old Italian tone and playability.
