Timpani I uses medium mallets. Timpani II uses soft mallets. Nothing subtle about that.
We'll see about that shortly, Bill, after I download, activate, install, and preview the Synchron Percussion II library. I trust Paul implicitly, so I'm inclined to believe that he and you are correct in that regard.
Still, however, as a quantitative and empirical methods geek, it's all about the ears. I just hope that they still work well enough to perceive and appreciate the difference.
best regards,
