I have recently encountered a problem (after a long time running Cubase without this problem)
When processing a piece of audio offline (using the “plug-ins” option) - for example a reverb with a long tail - I get piece of audio that looks ok (the waveform) but the audio fizzles out and cuts off about a second and a half into it (not as shown on the waveform - which is about 7-10 seconds long).
I have tried to restart my computer and open an empty project but the problem persists.
I also had a couple of cubase crashes (blaming my cubase.exe) when playing around with the offline processing in my original (heavy) project.
if I do a “bounce selection” on the “processed and cutoff” audio part (with the good waveform) - I get a new audio part with a cutoff waveform (which correlates to how it actually sounds)
