This sounds like a wonderful instrument and uses wonderful, ground-breaking technology. I fear its market is really limited to those relative few who will take the time and spend the money to seek it out, then develop it fully to their own needs.
To be really successful on a large scale, Wersi will most likely have to work on the OOTB package so there is more appeal to a vast market of users, not just the technophobes (and I use this term in a complimentary manner!) Then, they will have to find a way to market and distribute it worldwide.
It seems to me there are some similarities to the Ketron situation, where there is an excellent product that reaches a limited segment of the market.
Hope this makes sense. Go Wersi! Keep up the good work! I am past the point of wanting to make this kind of investment of time and money, but the long-term future of arrangers may well be in the balance, as we grey-beards die off and gracefully exit the market.
