Product Description

Refine your skills as a musician with the help of the Korg TM50 Instrument Tuner and Metronome. The Korg TM50 tuner allows you to use the tuner and metronome simultaneously. Since this single unit is all you need for both pitch and rhythm training, it has become a favorite lesson tool for brass bands as well as many other types of musicians.

The TM50 tuner features a two-level backlight that enhances the visibility of the LCD display. It uses a needle-style LCD for excellent response, and even greater tuning accuracy. In a first for this series, the Korg TM50 provides the Sound Back function that allows the speaker to generate the reference tone that's closest to the input sound, giving you a great way to develop and refine your sense of accurate pitch. The TM50 is the perfect daily practice partner that will support your development as a performer.

Tuner delivers outstanding functionality
The Korg TM50 tuner features extremely fast response to audio input from wind and other instruments, and the redesigned meter display method allows the pitch to be accurately and instantly shown without any time lag. Wind players will no longer experience the problem of their pitch changing spontaneously before it can be displayed accurately; this ensures that you'll be able to develop stable and drift-free pitch.

The detection range is extremely wide, extending from C1 (32.70 Hz) to C8 (4186.01Hz) which covers the note ranges of wind, string, and most other types of instruments. Even potentially difficult instruments that have a low pitch and numerous overtones can be tuned accurately, thanks to Korg's proprietary high-precision technology. The built-in high-sensitivity mic also allows easy and accurate tuning of acoustic instruments such as guitar and ukulele; alternatively, you can use the separately sold CM-100L contact mic to send the vibrations directly to the TM50 tuner for even greater reliability.

Sound Out Function
In addition to visual tuning using the meter, you can use the Sound Out function to produce a reference tone from the internal speaker or headphones, and tune by ear with the Korg TM50 tuner. You can specify the reference tone in a three-octave range from C3 (130.81 Hz) to C6 (1046.50 Hz) which covers a wide variety of instruments.

The TM50 tuner can be used not only to detect and inform you of pitch discrepancies, but also as a tool that helps you develop the ability to hear and produce the correct pitch. That's why the TM50 provides the proprietary Sound Back function.* Detecting the pitch of your audio input, this function sounds the nearest reference tone from the speaker while the meter shows the pitch difference between your input and the reference tone.
*This function is available for input via the INPUT jack or when using earphones.

Marks indicate pure major/minor third intervals
When performing in a brass band or orchestra, incorrect pitch is particularly noticeable for harmonic intervals of a third, yet by slightly skewing the pitch of a major or minor third interval from the equal-tempered pitch, you can obtain a more pure-sounding harmony that satisfies the ear. The meter scale of the Korg TM50 provides marks that indicate pure major and minor thirds relative to a given pitch; simply by tuning. When the needle aligns with the appropriate mark*, you'll be able to produce beautiful harmony when playing in an ensemble.
*When tuning to a pure major or minor third, the note that should be adjusted will depend on the music you're playing.

Fifteen Rhythm Metronome
Fifteen types* of rhythms are built in, including time signature numerators from 0 through 9, duplets, triplets, triplets without the center beat, quadruplets, quadruplets without the center beats. The tempo can be freely set in the range of 30--252 beats per minute. Sophisticated rhythms such as triplets and quadruplets with the center beats omitted can be useful for a diverse variety of styles including classical, rock, and jazz. The volume can also be adjusted, so you'll be able to use the metronome in any situation.
*If you're using the tuner and metronome simultaneously, triplets, triplets omitting the middle beat, quadruplets, and quadruplets omitting the center beats will not be available.

Easy Tempo Settings
When setting the tempo of the TM50, you can choose either ‘pendulum steps’ where the tempo will increment or decrement in the same numerical steps as on a mechanical metronome, or ‘full steps’ which allows you to specify any tempo between 30 and 252 in one-step increments. In addition, you can also use the tap tempo input to specify the desired tempo simply by pressing a switch in time with the beat.

Large LCD with Backlight
The large LCD display of the Korg TM50 tuner has a backlight that lets you adjust the brightness in two levels. In conjunction with the LED guide at the top of the display, this ensures excellent visibility, even when you're performing on a dim stage or in an orchestra pit. The characters shown in the display are also larger for improved readability.

Even More Compact and Lightweight
The Korg TM50 is even more compact and lightweight than previous models, and also boasts longer battery life. Attention has been paid to every detail, even including the back cover, and a folding stand is provided for stability in a free-standing position. The battery cover is now unified with the main case, eliminating any possibility of loss.

Memory Backup and Auto Power-Off
Even when you turn off the power, the Korg TM50 tuner will remember the tempo, beat, rhythm, calibration, and reference tone settings that you've specified (these settings will be initialized when you replace the battery). The Auto Power-Off feature will automatically turn off the power if twenty minutes have elapsed without any sound being input to the tuner while the metronome is not running.

What is your opinion of this product?
This is an very accurate tuner, and the metronome make it a great package. It has two level of backlight and an integrated stand that makes tuning (when changing strings) easier. Also a phone jack for the metronome for a "click" track. Sized to fit into a gig bag.
