i mean when i bounce to clip and save the project like that.
if i reopen the project, i can't undo it anymore. 
is there a way to get back to the original one in the futur? ty

Once you save, you've frozen a project in that state. "Save As" before bouncing, and you can recover the individual tracks. Even if you go through several different versions, you can always return to the one you "saved as," copy the tracks, and paste them into the latest version.
 
You can also just duplicate the tracks you want to bounce, then archive/hide them until you're sure you don't need them any more.

If I'm thinking correctly, the bounced clip generates a new file in your Audio directory for this Project (or your global Audio directory, if not using per-project Audio directories). If you can cross-reference the previous audio file, you could possibly re-import that original audio file into the project, or replace the bounced clip with it.

Yes, bounce generates a new file, but the original one will persist in the audio folder only if the project was saved at some point before the bounce.

thats a point it should be improved :) ty guys

It's pretty much SOP for any application that content created and then changed in the same session without being saved in between will not be recoverable in the next session. I don't see a problem.
 
The beauty of digital audio processing is that pretty much everything can be done non-destructively. It's generally not necessary to bounce anything until later in the project (if ever) at which point you should have saved several times along the way (preferably as separate versions), and have all your raw audio files preserved even if they're no longer linked to the project because they've been replaced by a bounce.

Same thing with word processors...when you click on save it saves the existing manuscript, not the one that existed before you started editing.

I'm guessing that the OP thinks that bouncing to clips is non-destructive. In a way he is right, since the original audio file is retained and can be retrieved, as Brconflict has pointed out.
 
But that's assuming that he is bouncing audio. He may be bouncing midi clips.

I agree it's not commonplace, however optionally saving undo history with Sonar projects could be a great enhancement providing it's implemented correctly (maybe saving undo history as a totally separate file), I don't see this being impossible to develop.

Yes! All wave clips are saved in the projects Audio folder... if you can figure out which ones they are, which is not all that hard to do unless you have a zillion of them.
 
When that happens I will save the project as "projectX.cwp" and then freeze everything and save again as "projectX.frozen.cwp.
