I have found a deterministic crash scenario in Cubase 6.0.4 (64bit) on W7 (64bit). The crash always occurs when you have a quadro output bus and you open the export audio mixdown dialog where you had set the MP3 output format earlier. Here are the reproduction steps:
- Open a new project and create a stereo output bus in VST Connections.
- Open the Export Audio Mixdown dialog and change the output format to MP3, then close the dialog (you actually don’t need to export anything).
- Go to VST Connections, drop the stereo output bus and create a quadro output bus. Set this quadro output bus as the main output bus.
- Now try to open the Export Audio Mixdown dialog again.
=> Cubase crashes.
This crash is obviously caused by the fact that the MP3 encoder is not compatible with the quadro channel setting. However, Cubase should be prepared for this situation.
