Stam,

There would be a lot less arrangers and workstations produced by Yamaha, Roland and Korg. The total market including PC arrangers would be a lot bigger but mainly dominated by firms that don't produce keyboards now.

Yamaha and Roland are ready to get a new share of the market. They already make sound chips and software that can be used in PC based arrangers. They could sell that for use in PC arrangers made by other companies.
