Newbie question here, I suspect this is some mode I've gotten myself into with the tracks, as the fades, track edits, et al, were working just fine earlier in my mix, but now none of the tracks respond audibly--to be clear, the basic audio plays back, it just ignores the fade/edit info--even though I can see the changes taking place on the screen. I've made some Melodyne edits, and some of the tracks are also showing a Render button in Event FX, not sure if that's also a factor. Hoping someone with more experience can offer advice.
Thanks!
