3.2 Resetting the device to factory settings
Operate as follows:
1. Switch off the device.
2. While keeping the buttons “Escape“, "Shift" and “Enter“ simultaneously pressed,
switch on the device.
Then follow the instructions on the display.
3.3 Tremolo tuning.
Supported by rapid exchange between two instrument programs.
To this end, you can use two consecutive instrument programs. Into the first instrument program
you will store a stretching for the deeper tones of the tremolo, the second on will contain the
stretching for the higher tones.
The special key switch to mode "CHOR" (See chapter 2.3.3.5)
In tune mode you quickly can change between the cent values of two consecutive instrument pro-
grams using the "special" keys.
3.4 PC data transmission
All settings that you've stored in the CTS-32-C you can save on a PC and store it back or transmit
it to another device.
To this end, you can install the software from the Internet ( http://www.tuninng-set.de ) or from the
enclosed CD. You also will find a detailed manual there.
4 Basic Information
4.1 Equal temperament
The standard tuning of the Tuning Set is the most frequently used equal temperament. The follow-
ing example shows exactly how it is conceived mathematically:
Target value: the concert pitch a' should be 440,00 Hertz
The frequency of the chromatic semitone steps are calculated accordingly:
b' = 440,00 Hz * 12 2 = 466,16 Hz 12 2 = 1,0594631
h' = 466,16 Hz * 12 2 = 493,88 Hz etc.
Target value: the concert pitch a' should be 442,00 Hertz
The result would be:
b' = 442,00 Hz * 12 2 = 468,28 Hz
h' = 468,28 Hz * 12 2 = 496,13 Hz etc.
4.2 The “cent” unit
The "cent" is a unit for frequency relations; a semitone step is divided geometrically into 100 parts.
The following calculation demonstrates how the “cent” unit is mathematically defined:
The frequency 440.00 Hertz are to be raised by 1 cent:
440.00 Hz * 1200 2 = 440,26 Hz
