Cubase Elements 6: MIDI Tempo Change (Linear Timebase)

I recorded a midi track freely but would now like to quantise it. Of course, notes are all over the place, so this doesn’t work. My goal then was to first change the tempo of the track, so things would match. I figured how to do this in C6, but Elements doesn’t seem to have the functions necessary. Or does it? Is there a way to do what I want? It seems that one of the big problems is that linear timebase only works for audio tracks in Elements?

Thank you!

Hm… was my question unclear? Or is it that everyone who has this kind of knowledge uses C6 and wouldn’t know about Elements?
