A great practice tool!

Offers both tuner and metronome functions simultaneously or independently. Its large LCD-type needle delivers both the accuracy of an LCD and the excellent visibility of a needle indicator. It also has LED indicators that show pitch deviation or blink to indicate the tempo, making the TM-40 a highly visual tool. Provides quick and accurate coverage of a wide spectrum of notes and pitches for wind, string, keyboard, and most other instruments

Excellent Functionality and a Wide Detection Range

With a detection range of C1 (32.70Hz) - C8 (4186.01Hz), the TM-40 provides quick and accurate coverage of a wide spectrum of notes and pitches for wind, string, keyboard, and most other instruments. Even low-pitched instruments with complex overtone structures are detected with the precision you expect from Korg. A built-in high-sensitivity mic allows acoustic instruments such as guitar and ukulele to be tuned easily and accurately.

Sound Out!

In addition to the visual tuning guide provided by the meter, you can use the Korg TM-40's built-in speaker to produce a tuning reference pitch (Sound Out). This is convenient for tuning by ear and is also useful for ear training. By pressing the Sound switch, you can select the reference pitch from A5 to B4 (usually used as the tuning standard for wind instruments). And by holding down the Sound switch, you can select a mode in which you step through chromatic pitches from C4 to C5 (one octave).

Adjustable Calibration

The TM-40's Calibration setting is adjustable in a range of 410-480Hz to accommodate a variety of tuning standards. The calibration can be adjusted in 1Hz steps, letting you accurately tune to any song or key. Memory backup is also provided so that the Calibration and Sound Out ("12 NOTES" or "ABb") settings are remembered even when the power is turned off.

Pure Major Third and Minor Third Interval Markings

When intervals of a third are played out of tune in the context of a brass band, orchestra, or other ensemble, it is particularly noticeable. But those intervals can be made to blend more pleasantly by slightly adjusting them (relative to the equal-tempered pitch) to a pure major or minor third. The Korg TM-40's meter scale provides markings to indicate pitches of a pure major and pure minor third relative to a selected pitch. By tuning your instrument so that the meter's indicator needle points to these markings, you can ensure beautiful harmonies when playing in an ensemble. This capability is very useful not only for wind instruments but also for vocal or a cappella practice.

The appropriate note to adjust when tuning to a pure major/minor third will depend on the music you are playing.

Metronome Section

The metronome section of the Korg TM-40 offers convenient functions for practicing a variety of music. Beat mode — choose from preset patterns. Beat mode lets you choose a preset tempo and time signature, and Tap mode lets you specify your own tempo. The compact TM-40's contains a large speaker that produces a clear and distinct metronome sound.

13 rhythm variations for practicing a wide range of styles. The TM-40 contains 13 types of rhythms that cover 0—7 beats per measure as well as doublets, triplets, triplets with center beats omitted, quadruplets, and quadruplets with center beats omitted. Tempo is easily adjustable in a range of 40—208BPM.

Sophisticated rhythms, such as triplets/quadruplets with center beats omitted, give you the flexibility to cover a wide range of styles from classical to rock and jazz. Since the volume is adjustable, the TM-40 can meet the needs of any situation, from private practice in a small room to sessions in a large studio.

When using the Tuner and Metronome functions simultaneously, triplets, triplets with center beats omitted, quadruplets, and quadruplets with center beats omitted are not available.

Tempo Adjustment Options

When you adjust the tempo setting, you can choose that the tempo value will increment or decrement either in "full-step" mode (steps of a single unit) or "pendulum-step" mode (steps of several units as on a mechanical metronome). Choose the mode that you prefer.

Set the Tempo with the Tap Function

The TM-40's Tap Tempo function lets you detect and set the desired tempo simply by pressing the Metronome mode START/STOP button at the desired timing in a range of 40—208 bpm. This makes it easy when practicing to a song that you don't know the tempo of, such as a recording on CD.

Memory Backup

With the Memory Backup feature, the Korg TM-40 remembers your Tempo, Beat, Calibration, and Reference Pitch settings even when powered-off.

Auto Power Off

After 20 minutes of no use, the Korg TM-40 Tuner Metronome will automatically turn off to extend battery life.
