kmetronome 1.0.0-3 (amd64 binary) in ubuntu focal

 KMetronome is a MIDI based metronome using the ALSA sequencer.
 .
 The intended audience are musicians and music students. Like the solid, real
 metronomes it is a tool to keep the rhythm while playing musical instruments.
 .
 It uses MIDI for sound generation instead of digital audio, allowing low CPU
 usage and very accurate timing thanks to the ALSA sequencer
