Oscillator Controls
Internal tone signals are generated by Summa’s oscillator which can be controlled from the oscillator setup area.
To access this, tap
OSCILLATOR in the Show menu.
Summa has one internal oscillator which is controlled using the two rotary controls towards the bottom of the window:
level and frequency. You can set the oscillator to generate a fixed tone at the specified frequency, or a stepped 20 Hz
to 20 kHz tone sweep.
Different tone sources can be set for each path width (mono, stereo and 5.1) using the internal and external tone
source buttons. Selecting
INTERNAL uses Summa’s internal oscillator as the tone source for that path width, whereas
selecting EXTERNAL uses the feed that is currently patched to Summa’s external tone input. Each leg of a stereo or
5.1 tone source can be muted individually.
