This is an issue no matter what song i'm working on. The sustain in playback will only sometimes trigger. Especially at the beginning of a song it almost never does the first time.
If i restart the song a couple times, it will work, but my problem is it will NEVER work when exporting a song. It will have no sustain for a bar or two and then the sustain appears again at certain trigger points.
I've tried adjusting the sustain line at multiple places at the beginning of the song and no matter what it always comes in and the same spot. Never right at the beginning.
