The violin and it's family have been around for a long time - do you think your device will be any improvement?
They are hard to play - the 10,000 hour rule works.
Without that investment in time, commitment ,training and enthusiasm, can you expect competant players to attempt the major string quartets of Beethoven, Mozart , Schubert etc or the gobsmackingly difficult and wonderful Sibelius concerto, or the Bach partita in Dminor - see Heifetz - using your device? And do it any better? or nearly as well?
Will major composers write concertos for it?
I doubt it.
to sum up - I think you're wasting your time.
sorry
