Imagine a keyboard with a choice for customers to choose for either semi weighted or a fully weighted keys. And with a choice for either the present 32 keys or 64 keys.
Think that a lot of people will like a Keystep with 64 weighted keys. Of course it will be a direct competitor to keyboard from other, for example the RD-64 by Roland. Keep the price at about €250,- and I think Arturia will sell lots of them.
The 32 keys of the Keystep are too cramped to play with two hands at the same time.
