Not sure what a ‘resonant phase rotator’ does exactly, but if you can be bothered chaining 98 modules together, you can patch the smear filter yourself! 
There are a few all-pas filters in the library, I have a patch using KRT J where I put about 20 in series and pinged them for a kind of DIY physical modelling.
I had to patch some feedback too to get it to resonate.

I don’t know much about the technology, but they both sound superb and inspiring in use. I could post a few videos.
Yeah I watched one on Smear a while ago, and it does sound good. Might have a go at emulating it very roughly in VCV at some point.
Venom Recurse helps a lot with long allpass chains. Does add a few samples latency, but in this scenario that usually isn’t a problem.

Yes, assuming your all pass filter is polyphonic

wow sounds really good
If I understood it correctly, I believe GroupDelay by Ambivalent Instruments does the same as Smoothie Audio’s SMEAR. (Though with less poles)

I tried GroupDelay actually, and couldn’t quite get it to do what I wanted. Even with feedback, there wasn’t enough resonance. I haven’t tried chaining loads together in series though, might be worth a go.
kind of off-topic but if you ping GroupDelay, with the right settings it makes a pretty sweet kick sound. The waveform will have some insane dc offset but that can be fixed by running it through something like Airwindows’ InfraSonic.

Yes! I was going to post this too. I tried a gate from the MIDI-CV module just to mess around, then processed it through VCV Gates to use the rising edge. I thought it was a pretty good kick!
What I found surprising is that chaining a few together in series doesn’t improve the sound, you get more resonance but lose the transient, so you’re not getting that nice ping at the start.
I also tried this with the VCV Phaser, because that’s basically a polyphonic 12-stage all-pass filter, isn’t it? A few of them together made a horrible distorted squeal, not what I was expecting at all.
I should really know the technical reason for why this is, but I haven’t worked it out yet….

If you keep the res at 0 it doesn’t blow up. But yeah, if you increase resonance in a chain of them, the signal level builds up over the chain and eventually hits some kinda non linearity. Probably a safety clipper, it sounds like. Can make some pretty gnarly sounds too, but very far from those nice clean pings…

Yes, resonance can quickly get out of control when chained. I typically only apply resonance to the last stage when chaining multiple resonant effects.
This is true internally for my Venom Multimode Filter. It has many slope options from 12dB/Octave to 96dB/Octave. Internally it is simply a chained series of 12dB/Octave (2 pole) state variable filters. The resonance is only applied to the last stage in the series.
Thanks, how would you patch that? (assuming you’re using feedback for resonance, maybe I’ve misunderstood)
I’m wondering how that 98-pole filter is configured internally now!
Well for the 16 pole (96 db/Octave) filter, there are 8 stages of filter, 2 poles each. The resonance value for the filter is only applied to the last (8th) 2 pole stage.
Edit - sorry. I hadn’t really looked at SMEAR until now. I didn’t realize that was what you were referring to.
Yep, I would need to have a long hard think about how to emulate that one!
Run out of brain bandwidth after work today, so it’s not happening for a while.
