I'd love the metronome to work without playing or recording

I'd love the metronome to work without playing or recording at all, so that when we are building a project, we can figure out the tempo before starting,  to hear it sonically, and to be able to adjust the tempo until it's just right!
 
Nothing fancy, just press play, and it plays until you press stop!

You might like this technique that I use for setting tempo to something I've been practicing and am ready to record:
 
- Disable Stop at Project End in Track View Options if it isn't already so you can run the transport in an empty project.
- Start playback with no click sounding, count off 2-4 measures in your head, and stop the transport on what should be the next downbeat.
- Shift+M to open Set Measure/Beat At Now, and enter that measure and beat (e.g. measure 5, beat 1).
- SONAR will reset the initial tempo to make the specified beat fall on the absolute Now time where you stopped the transport.
- Note that Set Measure will also insert a tempo change of the same value at the time you set. If you're going to be changing the initial tempo later, you'll want to delete that one.

Glad you liked it.
 
I Google keywords against site:forum.cakewalk.com to find things. If you have an idea who posted something or you know you posted in the thread, you can include usernames. Pretty much everything ever posted is still available which can make it difficult to narrow things down with common words like tempo and metronome.  This one might have been tricky to find if you didn't remember that 'brundlefly' posted it, and that it involved using 'Set Measure/Beat', or that a lot of the threads were about 'tap tempo'.
 
All the guys around here that seem to have minds like the proverbial steel trap are just masters of 'the Google'. 

I think that's a great idea! I usually just enable click on play and mess around till I find what I want, but I like this a lot!

Thanks for all the replies guys!
