How to get playback of cres and decres over multiple measures
I've looked through the bazillion posts on hairpins and the handbook, and I'm lost. My hairpins always instantly go from one dynamic marking to another during playback. I've tried changing velocity, multiple hidden crescendos and decrescendos, checking and unchecking single note dynamics, etc. etc. but the best I can do is step-wise markings to get something reasonably close to what I want. During playback, the sound always goes right to the next dynamic marking on the next played note regardless of how many measures I want the dynamic change to actually be.
Edit: added an example: bar 9. goes from mf to ff in one note when played back.
