You mean, like the string runs that are in the DVD (full) libraries?
There must be some reason the full libraries have their value...
Additionally, using various articulations, including PERF TRILL, with the speed parameter, makes for some very realistic run figures. And do this with multiple libraries and instruments for realism, and also constrain start/end of the existing runs, you can do some great work.
But I guess you need the full library for that.
