Called Roland support and they pointed out that the program numbers are from 0 - 56 for the rhythm sets in PR-H.
Roland forgot to provide the information on which program number is for which rhythm set in their manual, at least we couldn't find it.
I tried all 57 to find them and here is the program change numbers needed to call up all 9 sets, for anyone who is interested.
0 = STANDARD
8 = ROOM
16 = POWER
24 = ELECTRIC
25 = ANALOG
32 = JAZZ
40 = BRUSH
48 = ORCHSTRA
56 = SFX
