Audio Export automation is only accurate (for lack of a better term) if Render in Real time is chosen. I'm not sure if this is related to the latest updates (.033 and .036) but I have just noticed this issue after installing them. I have an envelope, on a sub, which fades quickly to -INF on the last note of a song so that there is no audible reverb trail . The automation works perfectly during playback but, when I export an Entire Mix render of the file (not in real-time), there is still reverb audible at the end. If I render the file in real-time, the automation works as intended (a workaround, but not optimal). I originally had an envelope on just the Breverb plug in and noticed this. Alternatively, I tried automating Breverb2 (Pro Channel) in case this might be successful, but I had the same result. Finally, I tried putting a volume envelope on the sub. Also, the same result (which really surprised me, lol!). Not sure what's happening here.
