I have no idea how many of those midi sounds were created by Yamaha or any other manufacturer, though lately, some are samples of the actual instrument that have been digitized.

This is the best I have been able to come up with - not perfect by any means, but I got a lot of accolades from really good musicians on another forum I frequent. Baker Street

All the best,

Gary cool
