I have similar struggle. I have recorded several MIDI tracks in one project and when I wanted to export it to mp3 or wave, it basically did not save anything. MIDI tracks are not muted. When it finally saved something, it was only empty something without any suffix. I have no idea what to do, becuase I’ve watched several videos on youtube, read several tutorials but none of them is using Cubase AI Elements 10.5. So if u have any idea what should I do, I will appriciate it very much.
