Audio Export, Bounce several tracks in one instance?

I am trying to accomplish some mastering techniques, but in order to do this I need to have to convert these files from midi to wav format. However I have to individually solo each channel. Is there a way to select individual channels and export them to their separate wav files all in one instance?

I know you can group channels but that only works with wav or mp3s I believe. Any thoughts?

I have just registered tape it but I don’t understand how to use it.
