So if this is feasible to market, how about one special string lib such as leg violins with 100 velocities?
The reason why the Vienna Imperial is possible is, iirc, that there exists a piano that can be actuated by a computer with very high precision, otherwise it would not be possible to record 100 distinguished layers. To do this with a violin, you have to find a way to achieve something similar. I never heard of a computer actuated violin...
