40 BPM Metronome

40 BPM (Beats per Minute) Metronome I designed this metronome series to emulate the behavior of mechanical metronomes as accurately as possible. Mechanical metronomes got some advantages over digital ones. The pendulum movement gives the musicians visual clues about the tempo which can be very useful, especially for slow tempos. Unfortunately, the timing of mechanical metronomes is often not very good at slow tempos resulting in uneven beats. Moreover, the loudness of mechanical metronomes is insufficient for drums practice and you can’t plug headphones on them.
