Unable to control volume levels

I cannot get Halion to control volume in my scores. There is no difference between P and MF and F, even though the score is marked, and crescendos and decrescendos are used. Anyone know what’s going on here?

Thanks,

What program are you using for your scores?

HALion should respond to velocity and midi cc messages. You need to set up your dynamics markings to alter the velocity or midi cc. Otherwise they are just visual markings and have no effect on playback.
