I am in the UK, and I bought a Ketron product because I believed it was the best instrument to work with for live performances.
I have raised several questions with Ketron concerning problems I had using their product, but as others have said, there is no response from Ketron, and I am left to struggle on to find my own solutions.
I still have faith that Ketron is a great company, and able to manufacture the sort of products that live performers will be able to benefit from. However, Ketron must wake up to the fact that issues are arising, and if the company does not address them then somewhere down the line they will lose sales.
