Metronome is a free metronome for Mac OS X.
Most functions (start/stop, change tempo &etc) use only one key to facilitate one-handed operation.
A unique Accelerator - begin a difficult piece slowly and gradually speed up by any rate to any maximum tempo
A Tempo Finder - use any key to tap a tempo and put it into the metronome
Save favourite settings for easy re-loading.
What is new in this release:
Metronome now begins as soon as you tell it to play, rather than waiting for one iteration of the time period specified as the bpm. Fixed a bug where bar counting during acceleration became erratic. Fixed a mysterious bug where the acceleration rate in the Accelerator Panel wouldn't let you enter a negative value to allow you to de-accelerate. Fixed a bug where users on pre-Leopard Mac OS X would see a useless 'Set Volume' button on the Countdown timer's window. Volume control over individual sounds used in Metronome is not supported on pre-Leopard systems.
