To the two Christians:
And, of course, you can:
File> Export > Track
Either way of exporting will "bounce" each individual track with its plugin processing independently between the start and end markers WITHOUT volume fader or pan settings. This assumes that you'll be mixing at a later point in the production. This only works if all sound making synths are soft (internal).
The Bounce function in the FIle menu will bounce all or selected tracks (depending whether they are soloed or muted) with their volume fader, pan setting AND automation and combine them into a single audio file. Offline will only bounce the internal stuff. Realtime will bounce internal and external sound sources.
Freezing creates a temporary 32 bit (floating point) internal audio file for each frozen track with its plugin processing to free up CPU. This works only in the current project and on the frozen track/s.
Sending tracks to a bus and then recording that bus on an audio track is another way to bounce a track, or, permanently submix a group of tracks with their individual processing, pan and volume fader info. This is useful if you want to have that combined track as on another audio track on the arrange page. This is also useful to internalize external sound sources and have them "in" the arrange as audio tracks enabling them to be frozen or "exported". Whew...so many options!
