If you are interested in a modular metronome, RTMix has a metronome whose meter and tempo can be continuously adjusted in the performance settings via preset script file, as well as utilizing real-time (MIDI) triggers. It can also show groupings of beats as a separate "rows of beats". For more info and screenshots see: (docs) http://meowing.ccm.uc.edu/~ico/RTMix-doc/ (metro screenshots -- the window/LED's are resizable, although that is not obvious from the given screenshots) http://meowing.ccm.uc.edu/~ico/RTMix-doc/3.html#3.6.4 (and finally more general screenshots) http://meowing.ccm.uc.edu/~ico/RTMix-doc/7.html#7.3 Note: RTMix does not generate beat sound by default, but it can be programmed to do so via script file. It's primary means of showcasing beats is via visual "led" displays.
