From the developer: "A metronome program that uses the computer's MIDI hardware (sound card) to play its sound. This program is very configurable. You can define any length measure up to 1000 beats with any beat emphasis you choose. More than fifty percussion instruments are available, and up to nine can be used at a time in a given measure definition. You can save and load your settings under as many presets as you like. All this and more in a tiny little download of only 18K."
