It was in the GLD at one point of firmware – but I don’t know wich, cause I never used it.
It’s a completly unnecessary feature, cause normaly you Use a Mic proper to your audiosource, and the GEQ is not for correcting, more for filtering unused (or feedback) frequencys and “styling” the sound (with all its con’s). So if you have the Idea to have an correcting EQ for every thinkable Mic, you have the wrong mic for you source.
Sorry: My Opinion.
As far as I know: There are no such preset EQ’s, but: Maybe the format of the library is close enough to the the new format, und you might be able to transport it by simply copy it via usb stick an replacing the EQlibrary into the avantis Folder on the stick. If that works, it might be a bit faster than rebuilding them manualy
