About Korg GM-1

It's time to elevate your group practice sessions with the GM-1 Group Metronome, a compact, earphone-style metronome designed to synchronize tempo across multiple devices. Ideal for marching bands, dance teams, and any group rehearsals requiring movement, the GM-1 ensures everyone can practice in perfect harmony, regardless of their physical distance.

The GM-1 is a revolutionary tool that fits comfortably and securely in your ear, much like a standard earphone. Its canal-type earpiece delivers clear metronome sounds, even amidst ambient noise, allowing you to stay in tune with the rhythm. This innovative design also prevents sound leakage, ensuring a quiet environment remains undisturbed.

With the GM-1, synchronization is effortless. Using infrared communication, it connects with other GM-1 devices to align the tempo. Simply set the sync settings once, adjust the tempo on each device, and experience the magic of unified rhythm. Whether you're practicing as a large group or maintaining distance, the GM-1 ensures everyone can keep time with the same beat.

The GM-1 also boasts a memory backup function, automatically saving your previous settings. This feature allows you to pick up where you left off, starting your practice session as soon as you power on the device.

Designed for mobility, the GM-1 is the perfect companion for rehearsals requiring movement. It comes with S, M, and L-sized earpieces for a precise fit and features a rotating part that adjusts to the direction of your ear. An ear clip secures the device to your earlobe, providing stability during active rehearsals.

The GM-1 offers a wide range of tempo settings, from 30-252 beats per minute, and supports time signatures from zero to nine beats. It includes rhythm variations such as quarter notes, duplets, triplets, quadruplets, and more, all programmable to suit your musical needs. The device also allows you to change the click pitch in three stages, enabling you to select a pitch that complements your instrument and environment.

Operation is intuitive with the GM-1's jog switch, located on the side of the body. This feature allows you to adjust the tempo, beat, rhythm, and volume without removing the device from your ear. An LCD display on the inside of the body provides clear visibility of tempo and other settings.

Despite its compact size, the GM-1 offers approximately 100 hours of continuous operation with a coin-type lithium battery. The battery is easily replaceable, ensuring your practice sessions are never interrupted. Experience the power of synchronized rhythm with the GM-1 Group Metronome.
