i alwys found cubase a bit of a bitch to automate.... some VST would when others wouldnt, and God save us, if you ever wanted to automate the Waves plugs ins...

the only way i can think of it is to control your intrument with a midi controller and then you can save the automation within the midi track...

but as i said i never really figured it out properly.

piss easy in ableton tho
