How it works
Metronome 11/16: the number counts sixteenth notes, eleven to a bar, so 240 is quarter note = 60. The clicks fall 2+2+3+2+2, which Wikipedia's article on Bulgarian folk dance gives as the rhythm of the kopanitsa.

Start
Tap the pad, or press Space. Clicks one, three, five, eight and ten are raised, with one the highest. Tap again and it stops.
Change the tempo
Tap the number under the pad and type a sixteenth-note tempo, or go up and down with minus and plus. For a quarter-note mark type four times its figure, to 1000 at most.
Questions and answers
How do you count 11/16?
Quick, quick, slow, quick, quick: five beats, each beginning on a raised click, the slow one three sixteenth notes long and the rest two. Wikipedia's article on Bulgarian folk dance says dancers often talk of quick and slow rather than a steady one, two, three.
Why is the kopanitsa written in 11/16 and not 11/8?
It is written both ways. The Bulgarian folk dance article lists it in 11/16 and calls the choice of 8 or 16 a notational convenience that follows regional practice and the speed of the tune. Wikipedia's Kopanitsa article opens with 11/8.
Do musicians play 11/16 as dancers count it?
Not always. Wikipedia's Bulgarian folk dance article says a tune may be played with its main accent on note one and lesser ones on five and eight, which its list writes 4+3+4. All three are raised clicks on this pad, so the bar still fits.
Which dances are in 11/16?
Kopanitsa and gankino horo, Bulgarian line dances, and by Wikipedia's Kopanitsa article similar dances under other names in North Macedonia and Serbia. In western Thrace, it adds, an 11/16 dance is often called krivo, which means crooked or uneven.
Why can't I hear the metronome?
The click may be going somewhere you are not listening: to Bluetooth headphones, or nowhere at all if the phone's ring switch is on silent or its volume is at zero. The eleven dots still step through the bar, five of them larger.
