Sorry for the multiple edits
After thinking this thru you may be right; the ACW doesn't actually move MIDI events.
There is a newer feature for a 'Click track' that may help. It allows auto-aligning tracks to a separate click track .. I haven't dabbled much with this but know others have had success with it

From Manual

Align Music to Click Track
This feature attempts to align a track of music that was recorded in free time to a click track. It tries to take a free time track and make adjustments to the times of the events so that the music becomes a standard track that can be synced to a metronome.
You can now easily record a click track along with any audio and/or MIDI, and then have RealBand automatically line up everything with tempo and time signature changes. This can have many useful applications. For example, if you recorded a strumming guitar in free time, RealBand can line it up to the grid so you can add loops, RealDrums, or RealTracks. Or, if you have just purchased a song from iTunes, you can have it line up to the grid in RealBand to make it easier for you to learn. Or, if you have recorded MIDI (not to a click track), and you can have that MIDI line up to the grid without affecting the actual performance.
