CUEMIX FX

TUNER

The Tu n e r window is an accurate and easy to use

tuner.

Opening the Tuner

Each MOTU audio interface has its own Tuner

window. Choose the Tun e r item from the Devices

menu under the desired interface (Figure 9-6 on

page 57).

Choosing a channel to tune

The Tuner follows the currently chosen Scope

channels (Figure 9-1 on page 52).

In the Tuner window, the displayed channel pair is

shown in the lower left corner. Each channel has a

checkbox to enable or disable its input to the tuner.

Tuner controls

Detected frequency: fundamental frequency of the

incoming signal, in Hertz (Hz).

Detected note: note name and octave that

correspond to the detected fundamental

frequency.

Meter: representation of the pitch difference

between the detected note and the detected

fundamental frequency. The horizontal position of

the illuminated segments indicates how far the

detected frequency is from the detected note. The

number of illuminated segments indicates

uncertainty or inharmonicity in the signal; a

greater number of illuminated segments represents

greater uncertainty. The color of the segments

changes gradually from green (in tune) to yellow,

orange, and red (progressively further out of tune).

Meter value: difference between the detected note

and the detected frequency, in cents.

Arrows: the direction in which the detected

frequency needs to move to match the frequency of

the detected note. The color of the arrows changes

progressively in the same manner as the meter

segments. When the detected fundamental

frequency matches the detected note within

three cents, both arrows will be illuminated.

Reference frequency: sets the frequency reference

for the pitch A4, between 400 and 480 Hz. The

default frequency is 440 Hz. The reference

frequency can be adjusted by dragging on the bar

below the number, or by clicking the number and

typing a value. To reset the tuner to the default

frequency, double-click the slider, or click the

number, press the Delete key, and press Enter.

Tuning stereo signals

When tuning a stereo signal, the tuner analyzes the

sum of the two channels. If the channels are not

phase coherent, the tuner may not be able to

measure the frequency of the signal. To tune only

one channel of the channel pair, disable one of the

channels as described in “Choosing a channel to

tune”.

CONFIGURATIONS MENU

A conﬁguration is just like a hardware preset (a

“snapshot” of all settings in CueMix FX and

therefore the 4pre hardware itself), except that it

can be created and managed using the CueMix FX

software on your computer, completely

independently of the 4pre hardware. The

commands in the Conﬁgurations menu let you

create, save, load, import, export and otherwise

manage as many conﬁgurations as you wish.
