I am not sure how to set the velocity of individual notes on wind instruments when working with midi tracks. The problem is most noticeable to me in the sound of a trumpet. I do not get a really nice trumpet sound. I know the mod wheel does the dynamics, but I'm not quite sure what the key velocity does and how it affects the overall sound of wind instruments. All this becomes crucial to me when I try to record mod wheel and foot pedal movements in real time. If I solo the instrument (say trumpet) and overdub mod wheel and foot pedal movements, I get a sound coming from my mixing board that is so soft that I can hardly hear any changes when I move the mod wheel. If I raise all the key velocities to 100% then I can hear the trumpet but I can't hear the mod wheel crescendos and decrescendos. But, when I play it back the mod wheel is too high for most of the track and the volume is past the O Db mark.
What am I missing?
