The SA and SA2 Voices are great but to get the most out of them you need to increase depth and velocity in the Voice Set Screen. The higher the setting the more articulation is sounded. You will need to find a setting to match your fingering. If the settings are too low ( below 68 for each ) it will be more difficult to get the articulations. These articulations add so much realism. Play with those settings until you find a combination that works for you.
