for precise pitch accuracy, versatile functionality, and with careful attention
paid even to the movement of the needle, the OT-120M Orchestral Tuner allows ideal
tuning under any conditions, with an incredibly broad tuning spectrum that covers
the pitch ranges of all instruments.
The OT-120M is the newest model in Korg's lineup of tuners whose precision and
functionality has made them the choice of musicians around the world. The OT-120M
features a dual display with both a VU-style meter for accurate pitch indication
and an LCD screen for excellent visibility.
with its advanced functionality, operation is simple, with intuitively understandable
switches and dial. It provides a wide range of pitches and a variety of tuning
methods, including a Sound Back mode that lets you check the pitch both by eye
and ear. Housed in a compact package, the OT-120M orchestral tuner provides all
the functionality you need for everything from transposing instruments to historical
Featuring a dual display with a VU-style meter for accurate pitch indication plus
an LCD screen
The dual display of the OT-120M provides a VU-style meter to guarantee high-precision
tuning as well as an LCD screen that shows not just the correct pitch, but also
the sound output level, calibration, key or temperament, and much more at a glance.
Its broad range (A0-C8) provides instant coverage for all notes and ranges of
wind, string, and keyboard instruments. The response of the needle to an input
sound can be adjusted over three levels, from quick response for rapid tuning
to slow response for careful tuning. Calibration can be adjusted over an exceptionally
wide range to support any concert pitch.
Versatile tuning methods include Auto/Manual modes and Sound Back mode
You can choose from two tuning modes: Auto mode in which the pitch of a single
note played on your instrument is detected automatically, or Manual mode in which
the desired pitch can be specified in detail. A reference tone can be sounded,
allowing two or more musicians to tune simultaneously. The sound output level
can be adjusted in two levels, covering situations ranging from small studios
addition, Sound Back mode detects the pitch that is input via the included contact
mic to the input jack, and sounds the closest reference pitch from the built-in
speaker. Since the meter also operates, you can verify the pitch by both eye and
ear, which allows you to hone your sense of pitch and to tune more accurately.
The built-in mic is ideal for pitch measurement of any acoustic instrument.
for transposing instruments and historical temperaments
As a convenience for transposing instruments, twelve keys including both sharps
and flats are supported. The Multi Temperament function provides eight frequently-used
historical temperaments, making the OT-120M the ideal choice for use with specific
classical and other tunings.

in very noisy situations, such as band rooms and with rotten
brats yelling :-) Most online stores do not sell the meter this way.

with the OT-120M
tuning with this meter, observe the following:
The instruction manual which comes with the meter may fail to tell you that the
default tuning is Equal Temperament. Be sure to have nothing showing in the upper
right corner of the digital display. This will then be Equal Temperament. The
other eight tunings are not very useful for the novice, so leave them alone unless
you know what they are for. Be sure to read the instructions and do not lose them
so you can refer to them for the abbreviations of the classic tuning temperaments.
tune "F" to "F" over middle "C". Be sure to learn
in the CD instructions, Appendix One, how to check your
temperament in "F" to "F" in the middle of the keyboard by
using Thirds and Sixths. This way you can tell if you got each note right.
3. After tuning
"F" to "F" in the middle of the keyboard, duplicate this octave
all the way to the bass end and then the treble end as in the CD instructions
in Appendix One.
"Stretch" is not included in this meter, so
you will need to do the stretch in this way. When you reach "C" of the
low end of the second from the last octave in the treble, begin to raise each
note slightly. At first, only 2 to 4 cents sharp will do. As you approach the
middle of the second from top octave, raise the needle to show about 6 to 7 cents
sharp. Taper the rest of the tuning, from the middle of the second from top octave
to the last notes until the last notes are about 15 to 20 cents sharp on most
pianos. You can go a little higher on spinets and consoles which go out of tune
