6 Click the Latency Detection (Ping) button if you want to detect and compensate for any delay
between the selected output and input.
When you start playback, the signals of any channel strips routed to the aux channel chosen in
step 3 are processed by the external eects unit.
Test Oscillator
Test Oscillator is useful for tuning studio equipment and instruments and can be inserted as both
an instrument or eect plug-in. It operates in two modes, generating either a static frequency or
a sine sweep.
In the rst mode, which is the default mode, it starts generating the test signal as soon as it is
inserted. You can switch it o by bypassing it. In the second mode, which is activated by clicking
the Sine Sweep button, Test Oscillator generates a user-dened frequency spectrum tone sweep
when triggered with the Trigger button.
Test Oscillator parameters
•
Waveform buttons: Select the waveform to use for test tone generation. The Square Wave and
Needle Pulse waveforms are available as either aliased or anti-aliased versions—the latter
when used in conjunction with the Anti Aliased button; the Needle Pulse waveform is a single
needle impulse waveform.
Note: The Waveform buttons are disabled when the Sine Sweep button is turned on.
•
Frequency knob and eld: Rotate to set the frequency of the oscillator (the default is 1 kHz).
•
Sine Sweep button: Turn on to generate a sine wave sweep of the frequency spectrum you set
with the Start Freq and End Freq elds.
•
Time eld: Drag to set the duration of the sine wave sweep.
•
Start Freq(uency) and End Freq(uency) elds: Drag to set the oscillator frequency for the
beginning and end of the sine sweep.
•
Sweep Mode pop-up menu (Extended Parameters area): Choose a type of sweep curve—Linear
or Logarithmic.
•
Trigger button: Turn on to start the sine sweep.
•
Trigger pop-up menu: Choose the sine sweep mode:
•
Single: Triggers the sweep once.
•
Continuous: Triggers the sweep indenitely.
•
Level slider and eld: Drag to set the overall output level.
