And by “real”, I mean an EQ, like what you have on a mixer: frequency, Q and Gain … it’s dead necessary for mastering … could be just a simple single-band EQ, that would do nicely, since you can just create any number of instances if you need additional bands.
The EQ filters in the “Filter2” effect are no use - you don’t even have a gain control, and they don’t sound like EQs at all, even if by some remote technical definition they might be. (for example, the -15 and -6 dB EQ filter types sound more like they ADD something than filter something OUT) … frankly the EQ filter types all sound trashy, except perhaps the “PeakingEQ”, but it still doesn’t have a gain control, so it’s not really useful even though it sound pretty good.
Also, the way that the cutoff fader parameter range is rigged, it’s almost impossible to finetune the cutoff for bass frequencies.
And then of course there’s the “EQ 5” and “EQ 10”, which are the best choice for practical EQ’ing at the moment, but they’re not good for the kind of EQ’ing you need for everyday mastering, since you can’t control the center frequencies or Qs of the bands … you don’t see graphic equalizers used in studios for mastering either
