[ INST ] Tune parameter
In firmware version 1.20, the minimum frequency value for the Main/Sub/Xtra timbre layers was changed from 20Hz to
16Hz (C0), and the maximum frequency value was changed from 10,000Hz to 12,544Hz (G9). These instruments also now
conform to a Note-Pitch/Cent display, where one semitone interval = 100 cents.
When editing the instrument tuning parameters for the Main (MainTune), Sub (SubTune) and Extra (XtraTune) timbre
layers, it is possible switch the parameter display between frequency and Note-Pitch/Cent modes by pressing the left and
right buttons either side of the LCD display.
When frequency values (Hz) are displayed during editing, the frequency value can be adjusted in semitone intervals by
rotating the encoder wheel. Fine adjustments in 1 Hz steps can be made by simultaneously pushing in and rotating the
encoder wheel.
When either the minimum frequency value of 16Hz or maximum value of 12,544Hz is reached when rotating the encoder
wheel, the adjustment then continues by passing through octaves of the note A (…220Hz, 440Hz, 880Hz…).
When a particular frequency value is not desired, please adjust the value in 1Hz steps to obtain the desired frequency
value.
When Note-Pitch/Cent values are displayed during editing, the Note-Pitch is adjusted in semitone steps by rotating the
encoder, whereas the Cent value (/+00) is adjusted in 1 Cent steps by simultaneously pushing in and rotating the encoder.
The range of cent values is from -50 to +49. The table below shows the cent value ranges for the musical note A4, the note
G#4 a semitone below, and the note A#4 a semitone above.

Please note that the conversion from Hz to Note-Pitch/Cent is exact but the conversion from Note-Pitch/Cent to Hz is not
always exact because of value rounding.
For example, in the system the note C4 [C4/+00] is accurately calculated to be 261.625563Hz. However, when converting
from Note-Pitch/Cent mode to frequency mode, this value is rounded down to 262Hz. This corresponds to a +2 cent
tolerance for the note C4.
In earlier firmware versions, it was only possible to adjust the tuning in Note-Pitch values for the Main timbre layer
(MainTune). Following the release of firmware version 1.20, it became possible to adjust the tuning of the Main, Sub
and Extra timbre layers (MainTune, SubTune, XtraTune) using Note-Pitch/Cent values in semitone steps (100 cents). When
editing, If there are timbre layers that you do not wish to change, it is advised that you use the frequency (Hz) mode for
tuning.
