A great lesson and practice tool, the Korg TM-40 offers both tuner and metronome functions that can be used simultaneously or independently. A large LCD-type needle delivers both the accuracy of an LCD and excellent visibility of a needle indicator. The metronome tuner also has LED indicators that show pitch deviation or blink to indicate the tempo.

With a detection range of C1 (32.70 Hz) - C8 (4186.01 Hz), 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. A built-in high-sensitivity microphone allows acoustic instruments such as a guitar or ukulele to be tuned easily and accurately, and the separately available CM-100L contact microphone can be used to send the vibrations directly to the metronome tuner for even greater precision.

In addition to its visual tuning guidefunctionality, you can use the TM-40's built-in speaker to produce a tuning reference pitch (Sound Out)--convenient for tuning by ear and useful for ear training. The TM-40's Calibration setting is adjustable in a range of 410~480 Hz to accommodate a variety of tuning standards. The calibration can be adjusted in 1 Hz steps, letting you accurately tune to any song or key. Memory backup is also provided so that the Calibration and Sound Out settings are remembered even when the power is turned off.

The metronome function of the TM-40 features a Beat Mode, which lets you choose a preset tempo and time signature, while Tap mode lets you specify your own tempo. And with a large integrated speaker, the TM-40 produces a clear and distinct metronome sound. The TM-40 also includes 13 rhythm variations for practicing a wide range of styles.

The metronome section of this portable metronome offers convenient functions for practicing a variety of music--covering 0-7 beats per measure as well as doublets, triplets, triplets with center beats omitted, quadruplets, and quadruplets with center beats omitted. 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.

* Even if the pitch is within the range of detection, the TM-40 may be unable to detect the pitch if the sound contains numerous overtones (such as the low and high notes on an acoustic piano) or if the instrument has a rapid decay.
