Polypulser

A metronome for practising and performing.

Built by musicians and tested by musicians.

Set a tempo, choose how many beats a bar has, and give every beat its own accent and rhythm. Play polyrhythms, and keep your songs in setlists.

Arrange Beats in Lines

Lay out a bar the way you count it.

  1. Touch and hold a beat until it lifts.
  2. Drag it to another line, or onto New Line above or below.
  3. Let go. Every line can have a different number of beats, like 1 + 3 + 3 for a bar of 7.

The circular arrow in the corner brings back the automatic layout. Lines are saved with the song and stay the same in full screen.

Polyrhythms, Two Ways

Up to 8 lines, each with 1 to 16 notes spread evenly across one bar of 4/4, and each with its own sound. Switch with the Sequential | Parallel control at the top of the Poly screen.

Sequential

The lines take turns. Each plays for one bar, from top to bottom, then it starts again at the top. Untick a line to mute it while it keeps its turn.

Parallel

The lines you tick play at the same time, so you hear them against each other, like three against four.

Find the Golden Ratio

In full screen, optional grid lines mark three points in the bar, so you can see which notes fall closest to the golden ratio.

  • ½The half bar
  • φThe golden ratio, 0.618 of the bar
  • ⅔The shuffle point

In the picture, the ninth of 13 notes lands almost exactly on φ: it starts 8/13 of the way through the bar, about 0.615.

Every Beat, Your Way

Made for musicians who count in more than fours.

Four Accent Levels

Tap a beat to move it through Accent, Secondary Accent, Normal and Silent. The ^ and > marks tell the levels apart without relying on colour.

A Rhythm for Every Beat

Quarters, eighths and every combination of sixteenth notes and rests, written with dotted notes where possible. Eighth triplets too, and all 64 sixteenth-note triplet rhythms. The picker stays open so you can try them while it plays.

Bars Up to 32 Beats

Choose 1 to 32 quarter-note beats per bar. Show only the beats, as large as possible, full screen in portrait or landscape.

Watch Remote

Start and stop the metronome from your Apple Watch or Wear OS watch and switch songs of the active setlist. Turn the crown, or the bezel, to step through the songs. Your phone keeps playing the clicks.

Setlists

Save a setup as a song, put songs in order and keep a setlist for every band or gig. Share a setlist from the share menu, for example by message or email.

Sounds and Feel

Ten sound sets, from digital clicks to toms and cymbals, and tap tempo up to 1200 BPM. An optional pendulum and screen flash on the Basic screen, and it can play over your music or backing tracks.
