Ummm Logical Editor:
Being a MIDI guitarist from the early 90's the LE was a must learn.
Here is my approach(es):
1-When using it stop thinking like an artist/musician etc
and start thinking more 'scientific'. (similar but not quite the same)
2-Don't go in 'cold'. Decide want you want to accomplish and use a preset
that steers in that direction. There are many in Cubase. Tweak from there.
3-Save your tweak as a preset. You might need it later and you might forget how you got there.
(happened to me a lot at first)
4-Using LE custom presets along with KeyC's can really speed the workflo'.
