I've been using MediaCenter since version 8.
I have my system/subwoofer adjusted to be good for about 95% of my albums. That 5% is not good. Some albums just have too much low frequency content, that it is un-listenable with my current settings.
Yes I can use the parametric equalizer to fix the sound for those albums, but it's a manual thing to turn it on and off and make the adjustments. The fixed equalizer can help sometime, but the set points are not always right.
I've been using the AudoEQ plug-in and it uses the fixed equalizer, so it can help but not perfect. And while the controls seem to indicate that presets can be saved, I have no idea how to do it, or if there is a bug in the code.
I've explored Zones, but they will not auto switch zones in PlayingNow.
So again I suggest that MC allow parametric equalizer settings to be saved by name, and then applied on a track by track basis. That would allow us to fine tune a badly mixed album and have the settings be automatically applied from PlayingNow, switching automatically track by track as configured.
