What do the symbols mean at the beginning of realtracks and styles, eg ~~ _

Roy

Yes, cryptic, I agree.

If the name of a RealTracks style begins with a tilde (~) this indicates that it could be changed to a different RealTracks style at a higher tempo (provided you have allowed this in settings). Who would ever be able to remember these obscure codes?

I recall I asked for this to be explained years ago as in in-line explanation, but it never got off the ground.

OK, I think I also found the meaning of '~~'

The double Tilde means that the RealTrack being used is a substitute based on the tempo.

But everyone knew that already though (well, everyone except me...)
