it sounds very clean, but honestly i prefer filters with more vibe.
to me, in the analog world, the best filter is definitely the Moog filter.
in the digital world, while it's old and probably full of aliasing, the Nord Lead filter is still unmatched. Even the fxpansion DCAM synths filter sucks compared to it.
i've attached a sample of my Moog filter pedal. the exemple is a bit extreme, you don't put your filter in self oscillation all the time, but it has soooo much color / vibe.
now i'm perfectly fine with "the drop". i wouldn't do a dj set running audio through a pair of moogerfoogers ! there's definitely some overdrive in that circuit.
someone will say "get the UAD moog filter". nope. it sounds nothing like the real deal.
Looking forward to this one, the early sound demos sound very cool! Which other circuits/filter types are you planning on emulating? Will there be a dry/wet mix control in there somewhere?
Yes the cutoff is being controlled via midi and I've not implemented my dynamic smoothing algorithm yet, it's just got a dumb fixed frequency low pass filter on the incoming midi which is why you can hear some rounded steps. The cutoff is being updated at audio rate, which you can clearly hear on the envelope follower example, and I'll post some FM examples soon as well.

I have the UAD moog multimode. Do you mind posting unprocessed .wav file?

The main point The Drop is that is it clean when swept out of band, so you can use it on an entire mix with loads of drive and hear no change unless you sweep the filter into action.
I've generated a 4 pole Cascade example with the output driven which seems to be the kind of sound you prefer. I've not done a moog model yet, the Cascade is more like a Prophet-5 or Jupiter-8 in that it has 4 ota's cascaded instead of the 4 differential transistors in the Moog ladder.
(edit: I've also added a second example where I have increased the resonance from 120% to 150% to get it to scream a bit more in a painful kind of way)
Thanks to Hugo of Goldbaby for the input 808 drum loop, check out his excellent sample packs here: http://www.goldbaby.co.nz/

I've just finished initial coding on a Cascade filter, which is the same structure as used in a Prophet-5, Jupiter-8, and loads of other classic synths. I am going to look into doing some more structures as well, but it depends on cpu use and how clean they are when swept out of band to determine if they make the cut or not.
All the filters at this stage need fine tuning and for me to add self noise and other important characteristics of analog filters. These at the moment are "perfect" circuit models and will sound more detailed and interesting in the final product.
Yes there will be a mix control and power switches for both the low and highpass filter to save cpu if you only want one of them.
It may have come to my attention that you were responsible for the filters in Nerve.
I thank you dearly for great sounding extremely usable filters. I dig them a lot and the resonance is amazing on those... fantastic for bringing up harmonics!
So you can imagine that I'm stoked to use this one...
Again thank you and Steve for bringing and implementing such an easy great sounding way to filtering drums.
Yes I've given Steve some filter code around 8 years ago for use in Lucifer and he has used them in some other plugins as well. I'm not sure exactly which filter he uses in LFO tool, but I also coded the variable slope envelope algorithm that he uses in LFO tool. The filters in The Drop are on a completely different level to all those I have previously coded
if it will nail the Shermann sound I'll buy it straight away.
I'm not doing a model of a Sherman Filterbank, and I don't think the schematic is in the public domain anyway, so I doubt very much my plugin will sound like one. In fact I've never heard another analog filter sound like a Filterbank either, unless perhaps you can point me towards something that does and has a schematic in the public domain?
The next product from Cytomic is called "The Drop" and it's an analog modelled resonant filter plugin. I've finally got some audio examples of the first few filter types which you can check out here:

That was exactly my point. The already excellent sounding filters in Nerve get a lot of use... so I can imagine a dedicated plugin like this coming from you will be fantastic!
Looking out really close for this! Sounds really good when compared to my Ebbe und Flut. It has different colors but the quality is there!

I have been doing some investigations into moog ladders and have come up with some interesting results. You are right that it is completely different to other filter types and has very cool drive and interaction going on. I've found that if you drive the input the control current setting the cutoff frequency gets swamped, so you get modulation of the cutoff frequency by the incoming audio. I have confirmed this with a friends little phatty, and also a full circuit model in simetrix, as well as my own circuit model. The little phatty, and I'm pretty sure any other moog filter with an external input, has an input stage clipper that prevents this modulation from being too large, and so the drive you are hearing is I think largely due to that input stage being saturated, not the output stage as I previously guessed, so please ignore that previous audio example I did where I drove the output.
I'll post some audio examples when I get a chance, but I've got to reformat my hard drive since it got corrupted (I'm pretty sure by MacDisk when dual booting into windows 7), so I'm going through the pain of a full reformat and restore. I have everything backed up, so not a biggy, just takes time.
Here are the plots to show you what I mean, the first one is my model, the second one the simetrix circuit simulation packages model. The input signal is a 200 hz sin wave that decays away with time, and the filter is set to around 2khz and self oscillation, both signals are shown together on each plot.
The little phatty, and I'm pretty sure any other moog filter with an external input, has an input stage clipper that prevents this modulation from being too large, and so the drive you are hearing is I think largely due to that input stage being saturated, not the output stage as I previously guessed, so please ignore that previous audio example I did where I drove the output.
Take a look at the Moog Rogue schematic. The input goes into an op-amp stage with no clipping (i.e. any clipping would be at the power supply rails) and straight into the filter. The sound of this filter distorting is quite different than pre-filter distortion.
A sonic example, of my Rogue going into a simple looper (skip the first 15 seconds - I need to edit things):
The Moog Rogue is famous for its overdrive, which works exactly as you describe in that it is close to filter FM. In the above example, I would have had both the oscillator levels all the way up, and maybe a bit of noise at times. The intermodulation distortion between the oscillator frequencies is strong enough that setting the oscillators to a fifth produces a power-chord sound.
My guess is that many of the older and simpler Moogs, such as the Minimoog and Prodigy, have similar overdrive behavior to the Rogue. The Micromoog/Multimoog kept the oscillator levels to the filter in a more linear range, and IIRC the Memorymoog used a 3080 OTA in front of the filter which would have clipped the signal pre-filter.
I don't know what is going on in the Little Phatty, but the Moogerfooger pedals I have seem to rely on the LM13600 (or LM13700 - I haven't looked in there in a while) dual OTAs to adjust levels by CV. Which makes for a very powerful pedal, but if the signals are distorting pre-ladder input, it may change the sound away from the "classic" Moog filter overdrive.
I've been working hard on The Drop, specifically the envelopes and lfos, and it is about time I shared another audio example to give people an idea of what to expect. I haven't decided on the final parameters, but in this example I've got an lfo that varies smoothly from triangle to saw, and each edge has independent control over exponential curve shape, which gives a wide variety of useful modulation shapes. The sawlike input signal is actually another copy of The Drop outputting its lfo as audio:
