CUEMIX FX

In Min/Max mode, Min and Max set the lowest and

highest displayed frequencies (in Hertz).

Vertical controls (amplitude axis)

The Ve r t ic a l controls (Figure 10-7) operate

similarly to the Horizontal controls, except that

they conﬁgure the y-axis (amplitude).

In Zoom/Offset mode, Zoom sets the display zoom

from 1x to 100x, and Pos sets the center amplitude

of the graph.

In Min/Max mode, Min and Max set the smallest

and largest displayed amplitude.

Spectrogram controls

The Floor control (Figure 10-5) sets the amplitude

threshold for the spectrogram display, from -144

dB up to 1 dB.

The Alpha control (Figure 10-5) sets the opacity of

the spectrogram information displayed in the

graph, from 100% (fully visible) down to 0% (fully

hidden).

OSCILLOSCOPE

The Oscilloscope (Figure 10-10) graphs the

amplitude of an audio signal over time.

Amplitude is displayed on the y-axis and time is

displayed on the x-axis. A thick white vertical line

marks where time equals zero; a thick white

horizontal line marks where amplitude equals zero

(Figure 10-10, below).

Level meters are displayed to the right of the graph.

One or two meters are shown, depending on the

current view mode (see “View controls”).

Opening the oscilloscope

Each MOTU audio interface has its own

oscilloscope. To open an oscilloscope, choose the

Oscilloscope item from the Devices menu under the

desired interface (Figure 10-6).

Choosing a channel to display

The oscilloscope follows the currently chosen

Scope channels (Figure 10-1 on page 52).
