Ian I think its much bigger world wide then you might expect.
Possibly, Donny, but in my region, arranger keyboards were/are very popular, and Ketron (of any model) was barely a blip on the radar, and most people have never heard of it, despite the world becoming increasingly smaller due to the Internet.
If using an arranger keyboard (without backup, especially)is a pro musician's main means of income, one would have to be daft to be using an instrument with little or no support.
It's not just hardware/software reliability either...anyone can have an accident by bumping or dropping an instrument, or have a drink spilled on it.
Bachus,cars like Peugeot and Renault were tried here in Canada (especially in Quebec) but poor dealer service (and inadequate rust resistance preparation...plus dreadful depreciation) had a severe effect on their place in the market.
Why would inadequate or very rare support regarding an arranger keyboard be any different?
