Well it is like this…
1-In the beginning there was one big audio file.
2-I started cutting the file with cubase.
3-Some segments I bounced (Right Click-> Audio-> Bounce Selection) which gave me more audio files inside the Audio Folder.
4-Some segments I processed using Plugins (Right Click-> Plugins) and/or Process (Right Click-> Process) which gave me a more files inside the Edits Folder
5-Later on this track had a bunch of edits and bounced stuff and it all sounded very nice and without errors or Cubase crashes.
6-Rendering the whole track was no problem, and I proceded to “consolidate” the project and get rid of all the edits and make 1 track either by bouncing or anything and here came the problems…
I couldn’t “Bounce Selection” of all the edits together because I got that error. Since I couldn’t do that I wanted to check what was wrong but I had no info.
I wanted to see if I could “Freeze” the edits but I couldn’t find the option in the menu so I checked the manual in order to fine “Freeze Edits” (Page 255 of the Operating Manual in English) and it wasn’t where it was supposed to be inside Cubase.
Also, Offline processing history showed nothing.
It seems to me that Cubase thought everything was fine but I still got that message.
1-Internal Summing worked perfectly.
2-Batch Rendering that one track worked perfectly.
3-Solo-ing track and rendering the project worked perfectly but with all the added effects of the project.
I don’t like workarounds but I ended up using number 2 and manually and blindly cleaning up my project folder because Cubase couldn’t tell me what was wrong. I want that one hour of my life back Steinberg!
