logic pro with tyros 5 instruments

[gio]

hello to everyone

i have my tyros 5 hooked up to logic pro x.  i want to use voices like the legacy tutti and other sounds,

but everytime i turn off the keyboard and logic pro x , and load the arrangement,  all sounds default to piano..

i have read on another forum that i have to change the msb/lsb to get the voices which i have no idea at all

any help will do. thanks so much
