I got to thinking that the S-950 doesn't have the onboard voice creator program and I was right. That program no longer exists in the S950. However, and I suspect this will be the same in the T5. When you select any voice, lets say Grand Piano, and you are on the page of pianos, at the bottom of the display you'll see Voice Set, which actually stands for voice settings. Press the #6 button, and you are into a great program for changing every parameter of that selected voice, then have the option to save your settings to the Expansion/User area for voices. So the program did not go away, it's just in a different location and has all the same options.

Cheers,
