There is a DMGAudio EQ with a Butterworth option coming soon, yes.

Not yet 100% sure that the changes will make their way back into EQuality (would likely break control schema/sessions. Not keen on that).

How about a filters only plug-in with:

UAD Cambridge:

Low Cut / High Cut Filters
Four types of responses are provided: Coincident Pole, Bessel, Butterworth, and Elliptic. The numbers represent the filter order, i.e. Bessel 4 is a fourth-order filter. Each offers a different sound. The responses are more gentle on filters with lower numbers, and get steeper and more aggressive as the numbers increase. The coincident-pole filters are first-order filters cascaded in series and offer gentle slopes. Bessel filters are popular because of their smooth phase characteristic with decent rejection. Butterworth filters offer even stronger rejection. The Elliptic setting is about as "brick wall" as you can get. Generally speaking, more phase shifting occurs as the response gets steeper.

SSL X-EQ:

Critical: 'Critical Damped' filters simulate a chain of passive analogue RC (for high-cut) and CR (for low-cut) stages fixing a behaviour similar to a series of RC elements in vintage analogue equipment.

Bessel: Linear phase behaviour leads to no overshoot or ringing resulting from a sudden transition between signal levels. The drawback is a sluggish roll-off rate.

Gaussian: No ringing or overshoot in the time domain, but slow roll-off in the frequency domain.

Butterworth: Characterised by having a maximally flat magnitude response, ie. no amplitude ripple in the passband.

Chebychev: Characterised by having an equiripple magnitude response, meaning the magnitude increases and decreases regularly from DC to the cutoff frequency.

Wave Arts TrackPlug:

TrackPlug's brickwall filters are implemented using 10th order elliptical filters, with at least 90 dB of stopband attenuation and less than 0.1 dB of passband ripple.

That would be a really good plugin to have

DMG needs a good freebie, no? I use cleansweep quite a bit, but it only has the one type/slope. Maybe Dave could have mercy on us and roll all or at least some of the above plus some of his magic into some cleverly named filter plug-in? Oh, and add resonance where possible (think VOG). Please? Of course any other developers would be welcome to give it a shot. I have a good idea who would win, so why not skip the race and go straight to the finish line? (or maybe it could at least be for people who already have equality and/or equick)

Our next EQ will be killer; but there will never be an advantage to waiting - existing customers are always looked after, so there will be a preferential upgrade path for them. It won't replace EQuality - it will be it's big brother and it will cost more.

EQuick is what it's designed to be - a small, quick EQ for fast mix corrections where EQuality seems like overkill. It won't evolve much past where it is, because it doesn't need to. I wouldn't use it on my end chain (whilst I have EQuality), but it's great for sorting little issues out here and there.

Sorry KO, I didn't mean to leave your out of the praise, flattery and overt favor currying (or is that curry flavoring?).

EQuality's big brother ??????

OK now you got my attention ! lol (You had it anyway but you know what I mean)

EQuantity on the way then :D
