Under the 'Learn More' tab on feedback supression:
"The feedback analyzer can be set to one of three modes, depending on how aggressively the analysis will seek out potential feedback frequencies"
There seems to be two modes, not three? Universal and Vocal - yes?
Also... the FBS mode set in a SETUP does not seem to be saved after a re-start, even as a 'Scene'. Is there a way to select, say, 'Universal' mode as the default. Presently 'Vocal' seems to be the default setting.
