Currently, you can select a staff and by the right and left arrow on the direction pad step through the part note by note by rest - etc... It would be wonderful to select multiple staffs or full score and do the same thing, and have the pitches sustain no matter what articulation or duration. This is for verifying the "right" notes. Currently the only way to do this is to alter the playback tempo to very slowly. You still don't have the option of stopping on a single chord.
