Channel buttons: The currently
active input channel is highlighted.
Push the soft buttons below each
channel number to change inputs.
Measured Frequency: The
fundamental frequency of the
incoming signal.
Note Dif: Difference in Hz
between the incoming measured
frequency and its nearest note
frequency.
Nearest Note: The nearest note
name and frequency compared to
the incoming signal’s measured
frequency.
Next Note: The nearest note
in the chromatic scale to the
incoming signal’s measured
frequency.
Normalize: Push button 2-1
to turn ON/OFF normalization
processing of the input signal.
Used when the incoming signal
is signicantly less than 10V
peak-to-peak (e.g., +/-5V typical
oscillator signal).
The DATA’s Tuner program measures an incoming signal’s frequency and automatically displays the nearest note in the
chromatic scale, as well as calculates the difference in hertz from the nearest note. Any of the four input channels can be
selected for measurement, allowing for quick tuning of multiple signals (e.g., tuning four oscillators to make a chord).
Typical accuracy: +/- 0.01 Hz
Frequency range: 27.50 Hz - 4,068 Hz (spans notes A0 to B7)
Tuner - Display Overview
Normalization - Small Signals
Eurorack audio oscillators generally produce a 10V peak-to-peak (+/-5V) signal. If the input signal is signicantly less than this
(e.g., less than 6V peak-to-peak), engage the Tuner’s normalization function (button 2-1, top left) to maintain analysis of the
lesser signal. Note that normalization can effect measurement accuracy and is not recommended for use on signals > 2,200 Hz.
For measurement of high frequency, low amplitude signals, disengage the normalization function and boost the target signal
prior to input via an external gain amplier, buffered adder, or similar.
