The OddMeter metronome

This metronome can click very complex rhythms. In addition to the usual 4/4, 3/4, 2/2 etc. it can also play 9, 11, 13, etc. grouped however you want. As an example, 9-beat can be grouped either 3+2+2+2 or 2+2+3+2 depending on the piece of music.

I created it after a frustrated search for a metronome that could handle the song Sofias flykt (Spotify) by Maria Kalaniemi, which we played in my world music band Morfis (Spotify).

Sofias flykt has a theme with period 29/8 that the arranger Elias Castegren wrote as 7/8 + 7/8 + 7/8 + 8/8, which the rhythms section also plays. In contrast, the melody is more natural to feel as 4/4 + 13/16, grouped as 𝅘𝅥 𝅘𝅥 𝅘𝅥 𝅘𝅥 | 𝅘𝅥𝅮 𝅘𝅥𝅮𝅭 𝅘𝅥 𝅘𝅥, that is a straight 4 and a shortened four. Entering such things is easy in OddMeter.

The metronome can also handle everything else I've thrown at it, whether it's math metal, fusion, folk music, or tricky rhythm exercises. What it cannot do however is polyrhythms, like 11 over 7, but there are other tools that can do that (e.g. Done Snap Polyrhythm Metronome).
