What's GNU GTick?
GTick is a metronome application written for GNU/Linux and other UN*X-like operting systems supporting different meters (Even, 2/4, 3/4, 4/4 and more) and speeds ranging from 10 to 1000 bpm. It utilizes GTK+ and OSS (ALSA compatible). It is part of the GNU Project.
This program has been originally written by Alex Roberts, but since he didn't have the time to develop and maintain it further, I (Roland Stigge) took it over (initially to package it for Debian, but there were too many "upstream" issues, so I decided to maintain the whole package). Since then, the program has been mainly rewritten (new DSP core, GTK+2 port, added features).
