There is something odd with the BandPass LP/HP filter in MXXX as it is letting through frequencies that should be removed by a bandpass. Looking in plugin doctor confirms the same.
This only happens when Bandpass is used in conjunction with other effects. When used on itself it works properly.
Here, bypassed all other effects in the chain and you can see the Lowpass 24 @ 20Hz having some problems... This is audible as well, and I can't get a clean LP filter working out of it in the patch.

When moving frequency of the LP up this happens, you can also see the HP filter has a similar problem.

When doing the same with a normal EQ, similar results come out.

Again, this is visible in the audio processing as well in Ableton, the sound is NOT high passed going through the MXXX instance even with a HP filter at the start of the patch, it makes a notch filter (somehow). The same happens using a LP filter at the opposite side.
I'm absolutely puzzled why this is happening because when using the filter on its own, no such issues come forward as can be seen here:

When I noticed this in my patch when testing it, I though that perhaps one of the other effects is doing something odd... but the issue remains even when everything is bypassed. So there must be something in the background that is not behaving as it should. There are no other effects in this patch, just those which are visible on the screen. I can share you the patch in case you wish to see what's going on.
Hopefully not getting tired of me![:D]( "Very Happy")

Ok I give up, I'm just tired of this really. I removed every single piece of multiparameter, GUI, effect, everything(!) from this particular MXXX patch. I completely brought it to the INIT state, then dropped a BandPass into this now EMPTY instance, and it does this:

Is this instance just broken somehow?! Can that happen? When I load a new patch (like above) the BandPass LP/HP work as they should, but not in this patch?! I spend nearly 12 hours making a whole effect with its own GUI and everything and the patch just breaks, somehow? I can't believe it, I don't want to redo this![:(]( "Sad")
