Merging two projects. - SOLVED

Not that I know of. You have already described the method by copy and pasting tracks. You can't import tempo changes either as far as I know.

Short of what you've already explained I do not think there is a way to do it easily.

If you saved out each track of project 2 as a track template as that will preserve all your plugin and synth settings.

Then open those track templates in Project one. Of course you'll have to adjust where on the timeline all the track templates are and move them accordingly if you want to place that data after project one on the timeline. If that's not the case then your template tracks will just be added to the catalog of tracks you have in project one. Eg Project one has tracks 1 to 20 and you add 15 tracks from project two which would be tracks 21 to 35 occupying the same range in the timeline.

Bet your head hurts now.

Thanks - Track templates, that seems to make sense, at least for getting the VSTs across. I will play around with that later.

I don't think Track Templates contain any note/midi data, so these would have to be copied separately once all the synths & tracks are set up.
 
This being the case, it would make sense to 1) do a separate bounce to clip for all the midi tracks in Project 1 so they are all 1 contiguous clip, 2) slip edit the left hand side of each one so that it starts at 01:01:000, 3) with both projects open drag/copy each one to Project 2 to wherever you've set the Now Time in Project 2. I'd make sure Snap to Grid is ON and set to Measure so they'll all line up perfectly.
 
What about your buss structure in P1? Do you want to replicate this in P2 or use the existing P2 structure?
Automation?
Meter/Key changes?
Tempo changes?
 
This is potentially quite a lengthy job.

Fortunatly the project was still in an early stage so there were no busses set up or any automation. The drums were just REX audio loops in the project I wanted to copy, which is very unusual for me, usually it will be Superior or BFD with several busses and a lot of effects, (mostly pro-channel).

A font of knowledge is this forum. A bit of lateral thinking form Mudgel was all it needed!

Yep.
 
In track view, just hit View > Tile in Columns for a side by side view of them both
 
Just make sure that under Preferences > File > Advanced you have "Allow Only One Project at a Time UNchecked

So I can open Sonar twice (I realize I must change setting in pref's), and just drag clips to & fro?

You don't even need to open SONAR twice, you can have two projects within a single instance. Just don't maximize the windows if you want to see them both at once. I definitely recommend a dual monitor setup and stretching SONAR across it for this!
