It's also worth mentioning that room tone doesn't suddenly disappear in digital black like it does in case of a "roomy" sample (... which is why noise sticks out like a sore thumb).
Dietz, could you possibly explain that in different words? I don't quite follow. Are you just saying that room tone keeps going after the sample stops ringing?
In any case, I can honestly say that I haven't been bothered by samples since I used a Sequential Prophet 2002 (128K of memory, sounds loaded from one side of a floppy disc) - and then the studio's 2" tape noise drowned it out.
