I also used to freeze/move as a quick and easy way to get audio from a synth. While it is not entirely as quick, if you have a split instrument track (or multiple individual outs from, say, Addictive Drums) you can actually record the audio by arming the audio track and recording. This gets you the same result. For single synth it's way slower but for AD2 with multiple outs I don't really mind it.
