You can try some router rules. For instance, the following set does:
1. for notes with velocity < 40, vel. is set to 40
2. for notes with vel between 40 and 100, it is not changed
3. for notes with vel > 100, it is set to 100

router_begin note
router_par2 0 39 0 40
router_begin note
router_par2 40 100 1 0
router_begin note
router_par2 101 127 0 100
