The EQ III plug-in appears as three separate choices in the plug-in insert pop-up menu and in the AudioSuite menu:
The 1 Band EQ is available in TDM, RTAS, and AudioSuite formats.
The 1 Band EQ has its own window, with six selectable filter types.
The 7 Band EQ is available in TDM, RTAS, and AudioSuite formats. The 2–4 Band EQ is available in TDM and RTAS formats only.
The 7 Band EQ and the 2–4 Band EQ share the same window and identical controls, but with the 2–4 Band EQ, a limited number of the seven available bands can be active at the same time.
