KORG / GM-1 Group Metronome 4-Pack Manufacturer Outlet Item

Share the same tempo and hone your sense of rhythm. An earbud-style metronome you can practice with even while moving. Recommended for group practice in marching bands, dance teams, and similar groups.

A super-compact metronome that fits in one ear like an earbud, allowing multiple users to practice while each hears a synchronized tempo. Ideal for group practice in marching bands, dance teams, and other activities involving movement. Features canal-type earpieces that fit snugly in the ear, ensuring the metronome sound is clearly heard without being drowned out by ambient noise.

●Features
〇A metronome enabling tempo synchronization across multiple units, ideal for group practice.
Synchronize tempo by connecting units via infrared communication. Once synchronized, setting the same tempo ensures two units sound at the same timing (synchronization resets when power is turned off). This means that even if you repeat the synchronization setting from the master unit to a slave unit, and then from a slave unit to a grandchild unit, as long as the tempo settings are matched, all units will sound at the same timing as the master unit, making it easy to synchronize three or more units.

With a standard metronome, group practice requires everyone to gather within close proximity to hear the tempo of that single unit. However, with synchronization settings + tempo settings, units operate at the same tempo regardless of distance between them, allowing each person to practice while maintaining a comfortable spacing.

It also features a memory backup function that automatically retains the last settings used. This allows you to resume practicing individual exercises right from the moment you turn it on (*).

〇 Designed to be worn directly in the ear, making it ideal for practicing instruments that involve movement.

Because it's worn in the ear, it can be used in situations involving movement, such as marching bands or dance teams. It comes with S, M, and L sized earpieces to ensure a secure fit, allowing you to choose your preferred size. The part attaching the earpiece features a rotating mechanism to align with the orientation of the ear canal on either side. Furthermore, the ear clip grips the earlobe from below, securing it firmly at two points where it contacts the ear, allowing you to practice with confidence.

〇 Canal-type design delivers metronome sound directly for clear audibility.

Features earplug-type earpieces inserted into the ear canal for high sealing. This ensures easy audibility of the metronome sound while minimizing sound leakage to the outside, allowing use without disrupting quiet environments with clicks.

〇Extensive beat and rhythm variations, including support for irregular time signatures.
The tempo setting range is broad, from 30 to 252 beats per minute. Furthermore, it offers a wide variety of settings: beats can be set to 0.9 time, and rhythms include quarter notes, duplets, triplets, triplets with the middle beat omitted, triplets with the last beat omitted, quadruplets, quadruplets with the middle beat omitted, and quadruplets with the last beat omitted. This covers practice for a wide range of musical pieces.

〇Intuitive tempo setting via jog switch.
Equipped with a jog switch on the side of the body, allowing easy setting changes while worn on the ear. The jog switch can be used not only for tempo setting but also for adjusting beat, rhythm, and volume, delivering compact yet highly intuitive operation. An LCD display inside the body shows the current settings.
〇Energy-saving design enabling approximately 100 hours of continuous use.
Despite its ultra-compact size, it runs for approximately 100 hours on a coin-type lithium battery. The battery can be easily replaced by opening and closing the outer cover on the body.
〇Memory backup function automatically retains the last used settings.
