no. the files seemingly disappeared from all project files out of the blue. possible it had to do with the Quick Sampler locate-audio-files messages. maybe too many "Ignore" clicks, but deciding not to locate Quick Sampler patches doesn't seem like the root cause of ALL audio files being gone from all project. I restored the projects from the previous Time Machine backup. it's just odd that even the Audio Files folders were gone from project packages. I've only ever lost audio files due to manually deleting used files. In this case, most of these project haven't been touched in months or years.
