## What is SUS4 Metronome?

A click from 20 to 300 BPM that can also play 3 against 4.
Subdivisions, swing and clave grooves, and a left and right ear split for accent work.
Fully on-device: no cloud, no account.

Tap in the tempo or dial it. Pick a subdivision, turn on a polyrhythm and give each voice a different sound. Set a tempo ramp and it speeds up as you drill.

• 20 to 300 BPM, with tap tempo
• Subdivisions, swing and clave grooves
• Polyrhythms: two voices, one in each ear if you like
• Automatic tempo ramps for speed practice
• A library of click sounds
• Apple Watch app

For drummers, guitarists working up a fast passage, and anyone practicing odd groupings.

Pro, or SUS4 All-Access across the whole range, adds polyrhythms, the ear split and tempo ramps.

Made in the UK by working musicians.
