As promised in an earlier post, here are some threads I know of that discuss and show some examples of using the MIDI Logic Editor in Cubase:
Here’s one that discusses the editor in general…with some screen shots showing a few tricks, as well as some of its strengths and weaknesses.
Here’s one that discusses inserting CC1 events to automate some general dynamic entries with an orchestra library that uses CC1 instead of ‘key velocity’. I.E. It’d take all day to enter this sort of stuff by hand…but with a little script you can throw it in a few seconds. It also gives some hints on using mouse tools in the key-editors.
