This instrument tuner is accurate, fast and easy to use. Virtually all instruments
can be tuned with it. Also the possibility to check the tuning of instruments like
the accordion or button box can come in very handy. Instruments with a
beating sound like the accordion or button box can be checked without opening them.
So it is very easy to check if it is getting time to (let somebody) tune your
The instrument tuner runs on a pc or laptop with a Windows operating system. The
instrument tuner works with internal as well as with external microphones.
Please take some time to read this manual. This will certainly save you a lot of
time later on. If you find things missing, in error or unclear please send me an
1. Select the microphone.
You can do this by clicking on the 'menu' button and selecting 'settings'.
After this you can select the microphone from the list. If the instrument
tuner does not receive any microphone signal then this 'settings' screen
will pop up automatically. Check in the upper screen of the instrument tuner
if the selected microphone produces a signal.
2. Adjust the microphone's sensitivity.
You can do this by clicking on the 'Windows Microphone Settings' button in
the 'settings' screen. A Windows screen will be opened where you can adjust
your microphone's sensitivity (volume). Select the microphone you want to use
and adjust its volume. The Instrument Tuner's sound level gauge should go up
to three quarters of the scale while tuning a tone.
3. Start tuning.
Play the tone that you want to tune, and watch the bottom gauge to view the
deviation. The deviation of the tone is also given as a number in the “Cent 1” screen.
The trial version of the Instrument Tuner runs on every pc or laptop that conforms
to the system requirements as stated in this manual. You may install the trial
version of the Instrument Tuner on multiple computers and send it to your friends.
The trial version supports 1 out of every 3 tones of the scale. The other 2 tones
cannot be tuned. It is the intention that this is enough to test the Instrument Tuner.
The functions “transpose” and “quadra flat tuning” are not supported by the trial
version, all other functions are supported.

Which instruments can be tuned with this instrument tuner?
Virtually all instruments are supported by this instrument tuner. Think of: Guitar,
violin, flute, human voice or crank organ. Also instruments tuned with
beating like the accordion and the button box are supported. For these instruments
a special feature is present that can measure the amount of beating.
The instrument tuner is easy to use. There are a number of advanced features,
like the graphs, but these are not necessary for the tuning process. Also the
settings are kept to a minimum. All complicated things are configured automatically
as much as possible.
This sound level gauge displays the sound level of the measured tone. As soon as
the Instrument Tuner selects a tone to tune (the red bar) the sound level of this
tone is displayed. The sound level that is displayed here depends on the sensitivity
of the microphone that is configured in Windows. This gauge is not used for the
This screen displays the strength of the tones measured by the microphone.
From left to right the strengths of the B1 up to the C8 are displayed using bars.
The higher the strength of the tone, the higher the displayed bar. If multiple
tones are measured then multiple bars will be displayed. In this screen possible
overtones can be observed. The instrument tuner selects the tone that will be
tuned automatically from the tones that are displayed here. The selected tone is
indicated by a red bar. This screen is not used for the tuning process.
This screen displays the frequency spectrum of the note to be tuned. If an
instrument is tuned with beating like an accordion or button box, then the
tone actually is built up out of two tones that are produced by two reeds.
One tone has a pitch that is a little bit higher than the other's. The accuracy
of this screen is high enough to display these two tones as two independent
peaks. This means that you can actually see the beating of the tone! The further
the two peaks are apart, the faster the beating. The instrument tuner determines
the closest tone from the scale and indicates it with a vertical green line in
the middle of the screen. The measured peaks are indicated by vertical blue lines.
If a tone is tuned then its frequency should be the same as that of the tone from
the scale. In case of a single tone, the highest point of the peak should fall
on the green line. If the peak is on the right side of the green line then the
pitch is too high and if the peak is on the left side of the green line then the
pitch is too low. Due to the high accuracy of the instrument tuner it is not
necessary that the peak falls on the green line exactly. A small deviation can
not be detected by the human ear. The text in the lower left corner of this
screen ('1 tone' or '2 tones') indicates whether the instrument tuner searches
for one or two peaks. The text in the lower right corner ('Medi' or 'High')
indicates the precision that the tuner is working in. This screen gives valuable
information for the tuning process, but is not necessary.
This screen displays the note value of the measured tone. The note value is displayed
as a large character in the middle of the screen. To the top right side of the
character is sharp (#) can be shown. To the bottom right side of the character the
octave is shown as a number. In the upper right corner of this screen the frequency
of the A4 is displayed. Normally this is 440 Hz, but this value can be adjusted with
the slider at the right side of the Instrument Tuner. In the upper left corner the
frequency that the selected tone should have is displayed. In the lower left corner i
s displayed if and how much the Instrument Tuner transpones. The 'quadra flat tuning'
setting is displayed in the lower right corner.
This screen displays the deviation of the measured tone with respect to the
closest tone in the scale. The display ranges from 50 Cents too low to 50 Cents
too high. The blue line indicates the value of the measured tone. The measured
tone is tuned when the blue line is in the middle (on the green zero-line) of the
gauge. A small deviation (+/- 2 Cents) is permitted because this can not be
detected by the human ear. If the blue line is on the left side of the middle
then the tone is too low and if the blue line is on the right side of the middle
then the tone is too high. The number in the small screen “Cent 1” shows the
deviation of the tone in Cents.
If an instrument is tuned with beating, like the accordion or button box, then a
tone actually is build up out of two tones that are produced by two reeds. To be
able to measure these two tones, the Instrument Tuner must be configured for
“2 tones” and “high quality”. This can be configured with the two buttons “Tones”
and “Quality” on the bottom of the Instrument Tuner. Default, the Instrument Tuner
is configured for 1 tone. The instrument tuner will not be able to measure the
beating than! As soon as “2 tones” is configured, two blue lines will appear.
These lines indicate the pitches of the two tones. The distance between the two
blue lines indicates the amount of beating. The number in the small screen “Beating”
now indicates the distance between the two blue lines. So this number indicates
the amount of beating. The higher the number, the faster the beating. The desired
amount of beating depends on the pitch of the tone and is displayed in the small
screen “Desired”. The desired amount of beating for the C4 and the C6 is configurable
in the settings screen. The calculated desired beatings of the tones in between are
equally divided between these two configured beatings. During the tuning process the
values in the small screens “Beating” and “Desired” should become the same.
The precision of the Instrument Tuner can be set to high or medi (medium) with the
button 'Quality' on the bottom of the Instrument Tuner. The Instrument Tuner will
be slower in high precision. The medium precision will mostly be sufficient for tuning
single tones. For tuning two beating tones, high precision is necessary.
With the slider on the right side of the Instrument Tuner you can tune your
instrument in another pitch than the standard A=440Hz. With this slider you
can set the A frequency between 430Hz and 450Hz with 1Hz steps. All other keys
will change evenly. The current pitch (frequency) of the A is displayed in the
top of the screen that displays the note value.
With the 'trans' button on the bottom of the Instrument Tuner you can tune your
instrument in another key than the standard C. With this button you can transpose
to another key. The key that the C is currently transposed to is displayed in the
bottom of the screen that displays the note value.
Each time the 'flat' button is pressed, the number of b's will increase in the
bottom of the screen that displays the note value. This way it is possible to
tune 1 to 4 tones above the displayed note value. If the capo is used then it
is not necessary to remove it. Press multiple times on the 'flat' button depending
on the capo's position.
The deviation of a tone with respect to the closest tone in the scale is indicated
in Cent. 100 Cent is the distance between a tone in the scale and the next. If the
tone to be tuned has a deviation of 50 Cent then its pitch is between two tones
of the scale.
The instrument tuner configures its settings automatically as much as possible. This
way the instrument tuner is easy to use. So the number of settings is kept to a minimum.
By pressing on the button 'Menu' and selecting “Settings” the microphone to be used can
be selected and the desired beating can be configured. If the microphone does not work
right away then it is possible that your Windows settings are not configured as they should.
The Windows screen, where you can change the microphone settings, can be shown by clicking
on the 'Windows Microphone Settings' button.
