George,

You are correct. It would be wise to create an AUTOLOAD file that will automatically load these new sounds from the HD whenever the keyboard is turned on. Both sounds (Grand100 & 200) need to be loaded for the new Program "NewGrand" Piano to work properly since they are panned to the RIGHT and LEFT.

We chose the option of having you the User determine whether or not you wanted to load these sounds because if you choose this option, your boot up time will be slightly longer than if you just wanted to work with the current sounds in ROM.

All the other exclusive SD1Plus voices will have to be loaded from the HD and these voices have been designed for optimal perfomance on the SD1Plus.

Thanks,

AJ
