This happens to me off and on, and I can’t seem to get rid of it. Today it appears in a way where Wavelab (10.0.50) skips small sections when it approaches the end of the clip (last 3-4 seconds or so) + it cuts off the end of the clip about one second too early. I’ve been using multiple plugins on the clip, and as soon as I remove Ext FX, the problem goes away. The problem remains also when Ext FX is my only plugin on the clip. When I render the clip, it doesn’t skip around BUT it chops off the ending. This is extremely problematic, obviously.
Also, sometimes the timing of the audio and visual waveform representation is dead on, and sometimes it’s way off, like one full second.
I’ve been trying to detect Latency on Ext FX, changing buffer size up and down, all with no effect.
System is: Wavelab Pro 10.0.50.
