No they are manually created because they can be deleted. As I understand, the track's "actual" trsnsients (created by Audiosnap) cannot be deleted, just disabled.
Yes that's correct.
But these manually-created notes appear simply when enabling the audio-transient filter within a track. No manual-intervention otherwise. At least in my projects I've had to work around it. It's truly an annoyance, not a show-stopper. 5 minutes of work around (or less depending on the amount generated), and you're golden.
What sort of material is it? I've never seen it but I have a very set routine and most of my use is on live drums, mainly extracting timing from improvised recordings plus tidying up here and there and the odd bit of drum replacement.
I discovered that to get the best out of audiosnap material such as that is best trimmed, bounced and then the clip map checked. Any none relevant noise at the front of the clip such as studio chit chat, generally confuses audiosnap.
I haven't used it extensively on much else other than moving the odd bits of bass, guitar etc around
