Hi Andrew,

One tip would be that you would not necessarily need to fade out the  
first cue while you're fading up the second.  You could just fade up  
one on top of the other, and then send a stop to the first when it's  
no longer visible.  This cuts down on some work, with the same visual  
result.

Could you send me your workspace off list for me to try on my own  
MacBook Pro?  That way we can have the same reference point.

Best,
Chris
