lost a clip after an undo/redo

[soybalm]

I lost a short punch that I did. I punched in a mono vocal track while the playlist view was selected on the track. There was an existing take on the second lane. I was punching in the first lane which was the most recent take. We listened to the clip back and it sounded fine but I wanted to undo to A/B the older take and the new punch as I often do. After the undo, it wouldn't redo to get my punch back. I just had the singer punch the line in again but it was weird to immediately lose that clip. The clip list on the right didn't have the new clip as far as I could tell. It was just gone. Although I didn't check Windows Explorer. Maybe I accidentally hit a key that made it permanently erase but I think not. It happened so fast.

If you clicked undo(Ctrl-Z) right after the record pass, you undid the actual recording(which is destructive and cannot be "redo" restored). A better solution would have been to use the trimmer tool to drag the old region across the new one(leaving a little of the old one showing if possible). That way, you could either drag the edge back with the trimmer tool, or hit Ctrl-z to undo the drag edit, instead of undoing the recording. Sometimes I will duplicate a playlist before I do punch-in overdubs. Yes, I've been stung by that one myself

That's probably what I did. I'm glad to know this. I thought undo only destroyed the clip but the file was still somewhere on the drive. I'll have to remember that. I used to like logic where it would always ask me if I wanted to delete the file permanently. I could switch off the nag. Nuendo would always ask you when you closed if you wanted to delete unsaved audio. That kept the sessions lean.
Thanks!

I just experimented a bit. The file still exist on the hard drive even if you undo/redo playover etc. as long as you are making a fresh track, not a punch.It just gets orphaned. However if you punch, listen, undo, LISTEN, you can't redo unlike a regular recording. If you don't LISTEN to the original file you will get your punched in clip back.

I'm sure there is more to it. I should read up more on this.
