The Logic Off Topic list

I hate it when I'm trying to record an idea and I have to set the 
tempo first.  It kills the whole inspiration.  I wish I could hit a 
button afew times to the tempo I'm hearing in my head.  Is this 
possible in Logic.  I used to have an old metronome that allowed you 
to hit a tap button that would find the tempo for you.

TIA,

Orson
