I assume that all your tracks are audio tracks? If you don’t have channel batch export in cubase elements, than you’ll have to do it like this:
- Bounce all the tracks, so they have same exact starting point (for example, all tracks/files start at bar 1). You do this by selecting range with range selector tool for all your tracks in a project and than use bounce selection in audio menu. Make sure, that snap to grid is selected, so your selected range will be snapped to bar.
- Now use backup project command in file menu, create new folder on your disk, tick “remove unused files” and “freeze edits” and back up your project to a new folder.
- Now find this folder on a disk, go into sub-folder “Audio” and there you will find all the bounced audio files with the same starting point. Pack those into zip file en send them to mixing engineer.
Also make sure, that all the tracks are properly named (do this before bouncing, since file names will gate track names). The worst thing for a mixing engineer are weirdly named tracks/files. Also you have to be aware, that all those bounced tracks are pure clean recordings, without any vst effects (if you used any in your project). If you want your effects to be integrated into bounced files, than you’ll have to export one by one via export mixdown in your cubase elements, unfortunately.
Hope this helps
