The Test Oscillator is useful for tuning studio equipment and instruments, and can be inserted as both an instrument or effect plug-in. It operates in two modes, generating either a static frequency or a sine sweep.
In the first mode (default mode), it starts generating the test signal as soon as it is inserted. You can switch it off by bypassing it. In the second mode (activated by clicking the Sine Sweep button), Test Oscillator generates a user-defined frequency spectrum tone sweep—when triggered with the Trigger button.
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.
Needle Pulse is a single needle impulse waveform.
If the Sine Sweep button is active, the fixed oscillator settings in the Waveform section are disabled.
