- D2 Music From-To tempo transition [param1=Transition time, param2=Starting tempo, param3=Ending tempo]
- F0 Stop music
- F1 Stop sound effects (this will not affect operation 0x30)
Please Note
All transitions use the formula Transition_time (in seconds) = param1 / 60
The pan (audio L/R balance) values range from 0 to 127, where 0 is fully left, 64 is centre, and 127 is fully right.
The maximum game volume is 127.
The tempo value ranges from 0 to 64 (0x40). The normal tempo is 0.
It should also be noted that there is very likely no difference between operations 0x20 to 0x27. They all likely have the exact same outcome in FF7.
