Would you like Yamaha to reissue the fabled CS-80?
You can actually write to them and leave your ideas.
It's a wonderful use of people power.
You will need to sign up to the yamahasynthforum.

I just joined and left a message on Yamaha's forum
The question they ask is do you want a analogue re-issue or a modern evolution?
I want both.
