Using Tune Mode
Tune Mode displays CH 1 and CH 2 frequencies either by number of cycles-per-second (Hz) or by
Note Name. Once in Tune mode, simply press the encoder to toggle between the two display
options.
NOTE : The input signal must be at least +2V in order for the pitch detector to work.
Hz Display
The top line displays the frequency (in Hz) of
the signal appearing at CH 1, and the second
line displays the frequency of the signal
appearing at CH 2.
Note Name Display
The top line shows CH 1, and the second line
shows CH 2.
Zeroscope displays the note name closest to
the incoming pitch, plus a vertical line
indicating how far the pitch is from that note
(from -45 to +45 cents).
A note is sharp if the vertical line is to the right
of the note name. For example, in this
illustration the vertical line is to the right of the note name for CH 2, indicating that CH 2 is playing a
C3 (“middle C”), but that the note is sharp.
A note is flat if the vertical line is to the left of the note name.
A note is perfectly in tune if a box surrounds the note name. In this illustration, the box around the
note name for CH 1 indicates that it’s playing a C1 note, and that it’s perfectly in tune.
