RDM  It works just fine, provided you aren't in the widgets window (F12). When viewing the widgets page, the metronome is affected by other widgets for some reason, and doesn't play in time. This would be very high on my list of fixes.

DAVEED  Glad it's free. Now all I have to do is figure out how to delete it.

Suggestions:

1. Make one that plays in time.

2. Include all tempos, not just traditional skips. I need 102, not 100 or 104.

CHOD  Simple and does what it says. I find it a lot less annoying than some other metronomes I've used... and everyone knows singers and piano players need metronomes.
