Yeah, it just takes the time - I've spent too much perhaps, but it makes it easy to find some problems very quickly. And you're welcome for the time, pass it on to someone else in the forumIn 5 minutes you did what takes me an hour of RTFM's and googling
I save after anything significant. I add a new (incremental) number to the name. Don't wait too long - your backups folder of the current project can have back ups with corruption if you don't catch it right away. I might lay down drums, then add bass, naming the project "whatever name" 02 add bass. Adding guitar would be "whatever name" 03 add guitar. If I do overdubs on the guitar I'll save that under a new number with "gtr dubs" added to the name. I guess I'm really trying to encourage to save under a new name OFTEN.I do have a habit of saving a copy with a slightly different name after doing a lot of work.
I don't know what your dynamic range is, but make sure you're in 24 bit for audio recording... and, you may get away with some clipping on the tracks - use your ears if in doubt.I am afraid I'm getting obsessed with the individual channel strip peaks-any lower on those faders and there will be no sound at all
