Logic Pro/add instrument/click on track to select EZKeys/[very limited keyboards] browser& making sure FOLLOW SONG IS OFF/find the type of song/drag & drop into Logic/click on type of instrument I want to change it to [I 0="chose" 1="ESs24"]/clicked on Library in left corner/clicked on Piano/Clicked on type of piano. Supposedly that should take care of it. But I still here the EZKeys electric piano mixed with the grand piano on the same track.
