Can you make a design doc for how you plan to move the built-in EQs into the effect framework? ie where processing will move, any issues with existing CO / skin compatibility, etc. I'm very sensitive to EQ quality and while ours aren't The Best, they work nicely and previous changes have caused problems. So I want to be really sure we know what we're doing when we start rewriting such a core part of the engine.
