Time has moved on since I originally wrote this, and I don't have the more recent versions of either program: so I can't guarantee that the process will still work. However it's worth a try because Cubase LE's mixing facilities are way ahead of Garageband's.
I was using using GarageBand and Cubase LE or LE4. GarageBand was better for me for recording the initial MIDI, using its own instruments plus QT Instruments and Sound Fonts; but Cubase had an on-screen mixer with fader automation, so that you could make and adjust your mix in realtime and it would remember the fader settings and movements.
The is the procedure I used:
- Record all the MIDI and any real instruments. Don't bother
with effects
and only do a rough mix so you can tell what's going on.
- When you're happy with the tracks, click the padlock icon
on all of
them to lock them. Press 'play' and wait while the machine locks the
tracks. Stop play and save the project.
- Quit GarageBand.
Find the project file. Right-click on it and choose 'Show package
contents'. Inside the project is a folder called 'Freeze Files'. Copy
all the files out of this into a new folder and place it where it is
convenient for Cubase to be able to access it.
- The files
have code names. You can't drag them into Cubase LE as they stand for
some reason (I think they are 32 bit so that might be why), but you can
with LE4. If you open each
in an audio editor such as Amadeus, identify them, and save them with
the track title you can then drag them into Cubase LE.
- Open a new Cubase project: you don't need to create any empty tracks. Drag the newly saved tracks into Cubase and they will appear there. Now you can add effects and have the advantage of the fader-based automated mixing.
It's all a little
complicated, but though you can do automated level changes in
GarageBand by 'drawing' in the automation track, it's fiddly and
becomes a nuisance if
you have a lot to do. With the faders you can do a decent mix, then
automate any changes quite easily and hear what's happening as you do
it.
