Sorry for my delayed follow up. I've been ... well ... editing drums and creating tens of thousands of soundbites.

The good news is that I have not had the problem appear again. I've adopted a new practice of editing 10 bars or so (with on average 8 edits per bar), making sure my transitions are clean, merging, then deleting the unused soundbites, all the while saving project backups along the way. There may be some unnecessary steps in there, but knock wood, it's working fine now, and I can continue on with my absurd multitrack drum editing technique.
Hi mess,mess wrote: DP has ALWAYS stored SB edit data (start and end points, time stamps) in the parent audio file. This is true of all file formats (PT regions, etc). The sequence is storing all of the sequence specific data related to SB placement (what track, loops, fades, etc).
This makes a world of sense. As I posted earlier in this thread, even if I import audio files into a new DP project with the original project unavailable (either on another unmounted drive or simply deleted), the "child" soundbites appear in the new project for many (all?) of the previous edits made in prior projects / sessions ("sessions" for work done in PT ... ugh!).
Hi daniel,daniel.sneed wrote: BTW what's the actual size of the the DP file itself?
The DP project file with the approximately 30,000 soundbites is about 50 MB. I've been keeping my projects from the last week at fewer soundbites per the above, and they all seem to be staying below 30 MB.
Cheers,
Erik
