Korg GM-1 Group Metronome, 2 Piece

Full Description

Synchronised tempo for seamless group practice

The GM-1 revolutionises group rehearsals by enabling synchronisation across multiple devices. Infrared communication ensures every member hears the exact same tempo, no matter their position. This feature is especially useful for marching bands, dance teams, or ensembles practising across a larger area. Once synced, the settings remain intact until powered off, making it easy to pick up where you left off. No more struggling to stay in time—just set it and go.

Whether performing choreography or complex musical pieces, the GM-1 keeps everyone perfectly in rhythm, even when moving or spaced apart.

Compact, secure, and ready for movement

Designed for active rehearsals, the GM-1 fits snugly and securely in your ear with three earpiece size options and a dual-point attachment system. The rotating earpiece adapts to left or right ear use, and the ear clip keeps it firmly in place even during vigorous movement. This thoughtful design ensures the GM-1 remains comfortable and reliable, allowing you to focus entirely on your practice.

Its earphone-style build is ideal for practices requiring freedom of movement, such as marching routines or intricate dance rehearsals.

Customisable rhythms and intuitive control

With tempo settings ranging from 30–252 BPM, the GM-1 accommodates a variety of musical styles. It supports complex rhythms, including duplets, triplets, and quadruplets, along with time signatures from zero to nine beats. Customise the metronome’s click pitch to suit your environment or instrument, ensuring you never miss a beat. Adjustments are quick and easy thanks to the jog switch, which lets you change tempo, rhythm, and volume without removing the device from your ear. An LCD display on the inner body provides clear feedback, so you’re always in control.

Durable and efficient for long sessions

The GM-1 is engineered for endurance, offering up to 100 hours of continuous use on a single coin-type lithium battery. Its lightweight and compact form factor makes it easy to carry and comfortable to wear for extended periods. The battery compartment is designed for quick and hassle-free replacements, so you can stay focused on your music without interruptions. If you’re rehearsing intensively or performing regularly, the GM-1’s durability ensures it can keep up with your schedule.
