Hi Mac. It takes the length of the song at tempo to play and record to audio. The procedure is:

1. Click Audio Menu
2. Click Render Midi to Audio
3. Click (Re)-Render to Wav file. (For me using the SD2 and Edirol UA-4FX)

The are options in this window to select as you choose such as stereo file, 2-bar ending, etc..

I've never used the Audio Menu to select this in the past since it was accessed by clicking the .Wav button. That's changed now, but old dum dum (me) didn't figure it out right away.
