I recorded a drum solo to demo Glimmer Metronome, a Ruby-based metronome
GUI app that supports different beat counts, click sounds, and tempos,
including tap-based tempo calculation. It was built with Glimmer DSL for
SWT using JRuby to help me with my drumming practice. Glimmer Metronome
just received a new update in version 1.1.4 that adds menus and keyboard
shortcuts, thus becoming more user-friendly when using via the keyboard
alone.
