Product Description

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 (32.70 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 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, and the separately sold CM-100 contact mic can be used to send the vibrations directly to the tuner for even greater precision. Sound Out! In addition to the visual tuning guide provided by the meter, you can use the TM-40_s built-in speaker to produce a tuning reference pitch (Sound Out).

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

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

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

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.
