Product Description

Product Description

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.

See larger image.

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.

5.0 out of 5 stars Compact and well built tuner-metronome., September 1, 2005

By	A. maxon (eastern tn) - See all my reviews (REAL NAME)

This review is from: Korg TM-40 Large Display Digital Tuner and Metronome (Electronics)

This tuner/metronome is very well built and has a 12 note refrence. It works very well with my violin and I carry it with me to class and when I practice. The metronome has a loud beat. The tuner is loud so you can hear it over what you are playing. It has a large screen and is very easy to use. I recommend this to anyone that plays a string instrument.

5.0 out of 5 stars Not the best tuner or metronome, but perhaps the best for the price., November 11, 2006

By	Mark Gilbert (Atlanta, GA) - See all my reviews (REAL NAME)

This review is from: Korg TM-40 Large Display Digital Tuner and Metronome (Electronics)

I've always had difficulty finding tuners with adequate response, and this one was actually a downgrade from the OT-12 (my favourite pocket-sized tuner), but it surprised me by working better than any previous combined metronome-tuner while not costing much more. The response rate is not adjustable, but sits at about a medium (there has to be at least a second of sustenance, but not more than two if you're steady). The precision is about as good as most will ever need, although it's dubiously delineated between -3 and +3 cents. The rest of the spectrum to fifty is clear-cut (it is fully digital, for better or for worse). The accuracy is also as good as could be asked for at its price-range, but not great - you may want to let it cycle a couple times for the more troublesome notes or if you're of the end-inward school of tuning. There are no temperament settings, but very few musicians will miss that option. There is an input for contact mics, though the impedance choice is commodity. There is a mono-out as well, if memory serves (as opposed to stereo - monochannel is standard). Overall, the tuner is better than any budget-priced combination product I've ever seen (esp. the increasingly popular but rarely satisfactory Sabine MetroTune).

The metronome function is likewise fairly good. 7 beat options and some standard subdivision patterns, the usually discrete-option tempo selection (hence, precision not the most flexible, but not worse than similar combination products). Accuracy is fair enough but not great. It fits the r10 error rating given by the factory, as opposed to the r15/r18 of the very cheapest units or the excellent r2/r1 of purposeful objects like the Dr. Beat. Experienced musicians may wish to trust their instincts after getting the right idea from the metronome. The error is scalar, it will be less troublesome at lower tempos. The state of affairs in small and cheap timing devices is surprisingly bad, but this is certainly not the worst (for that, see Sabine, again).

Unlike most similar products that I've seen, the two primary functions can be used simultaneously (tuner and metronome). I don't use this aspect much but some customers might really like that (esp. instruments that will draw a faster response from the tuning function).

I cannot yet attest to the average battery life of the thing, except to say that it's at least not bad.

4.0 out of 5 stars Sensitive mic, February 24, 2006

By	Ich liebe cello (Seattle area) - See all my reviews

This review is from: Korg TM-40 Large Display Digital Tuner and Metronome (Electronics)

This tuner has been a wonderful aid in tuning our violins and cellos. I've found the mic to be too sensitive in our setting as it picks up my young children's voices while I'm trying to tune an instrument. I will be purchasing the pick-up mic accessory in hopes that it will insulate against the background noise. If you are able to tune your instrument in private, then this should not be a problem for you. Also, the tiny flip-out stand doesn't seem to provide adequate support when placed vertically on uneven surfaces like, say various surfaces of a cluttered piano. However, the pick-up mic should eliminate the need to position the tuner optimally in front of the instrument. This is less likely to be a legitimate drawback of the tuner design itself, and more likely to be one of my way of using it. In any event, I cannot imagine not using an electronic tuner for these or any other reason. It is truly a gift for those who play strings.
