I'm using the EXS24 regular timpani and, though I only just now had some success in producing a drum roll cresc. I can't seem to refine how I draw the note velocity mode line which goes every which way using the pencil tool. If I try to use the crescendo window and I select the notes and set it to 1-127 for example, it sets all the notes of the roll to 127 with no change. I don't get what I'm doing wrong. I also tried using the timpani crescendo sample but that doesn't seem to work at all.
