Thank you for taking the time to compile this list and test all the modules 
Yeah, the S&H section needs separate input voltages to produce different values. If I change that, I’ll get back to you

@Bloodbat: Different is not necessarily less useful, and since the module was modelled based on hardware, I wouldn’t make any changes just because it does not fit here. And the Utilities module by Audible Instruments also shows similar behavior.
In the example below, 9 different S&H modules (+ the 2 modules with same values across channels; bottom row) are compared. Each is slightly different in operation, all yield fixed random numbers in polyphony channels.

WALK (Bogaudio)
WALK (Bogaudio) responds to polyphonic inputs, which results in up to 16 different random functions.
Polyphony is gauged from one of the 4 input ports (rate, offset, scale or jump), depending on a setting in the context menu.

Poly Gate Modifier (Count Modula)
A polyphonic signal to the CV input of Poly Gate Modifier (Count Modula) modifies the individual gate length in up to 16 different channels.

Ah yep, I use that a lot, and Caudal as well. If we’re including modules that can be made polyphonic by sticking poly signals in, you can also do this with the VCV fundamental LFO / WT LFO (using the FM input) and probably loads of other stuff I haven’t tried too. One of my favourite tricks!
I may have to start a separate thread on poly effects modules!
The VCV LFOs are a good addition, will add.
Finding more would be welcome!
You are right, what is missing in this thread is modules specifically targeting polyphonic audio processing, is this what you are referring to with ‘effects’? It would probably include mixers and some of the panning/stereo effects you mentioned earlier.
I could add another category (Polyphonic Audio Processing Effects) with subs here if you want to suggest modules.
Also, one more could be added with Polyphonic Audio Oscillators, although these may be too obvious to find by a search in the library and there may be a lot, so I would not go down this path at this point in time.
You are right, however adding polyphony deviates from hardware anyway 
@Bloodbat nothing wrong with deviating from hardware, that’s the biggest advantage for software modular!
@Alphagem-O yep, audio processing modules are what I was referring to. I’m not sure about a category for VCOs, the majority seem to be polyphonic these days but I think it would make sense to do a separate thread for poly effects and keep this one for utilities?

Yes, even though it turned out that we went way past the ‘utilities’, this also made this thread and the list quite big already.
So, a separate thread and list with polyphonic audio effects might be good. Focus of the new list should be on audio processing, also trying to prevent confusion if a module can process audio as well as CV signals.
And it is probably less useful to list every polyphonic effect module straight from the library. Part of the idea in the utilities thread is to provide structure and straightforward access to modules that can fulfill certain tasks, in the sense of ‘What module(s) can I use to do this or that?’
Haha, true! It all depends on how much value it adds in relation to the work you need to put in

Array (PdArray)
Function generator with polyphonic control of up to 16 playheads/cursors reading hand-drawn, recorded or sample-based curves.

Medusa (Sanguine Mutants)
Flexible poly-to-poly multiplier.
MultiVoltimetro (NYSTHI)
Add channels to and subtract channels from a polyphonic list of channels.
People, at least quite a few who get in touch about the Mutants, seem to like polyphony a lot, so… that’s a fair amount of value, I think… … as for work… some are easier than others
I also like polyphony a lot, because (once I can wrap my head around its obvious and less obvious uses), the footprint of a patch can become so much smaller 
.
Thank you for putting all this extra work into the Sanguine modules; I very much appreciate them, too!

Polydelay (stocaudio)
An example of custom polyphonic phase shifting by polyphonically modulating the Time parameter of Polydelay (stocaudio).
Recurse (Venom)
Recurse is quite a versatile module when used with audio signals by patching different effects into its send-return path.
The module can also be used to multiply and change CVs. For example, by scaling and offsetting values with each recursion (e.g. using Offset by Bogaudio), a custom swarm of up to 16 functionally related values is created from a monophonic signal.
Alternatively, a polyphonic signal can be fed in. This reduces the number of recursions per input channel, because the maximum total number of 16 channels cannot be exceeded. So, 2 input channels will yield up to 8 recursions, 4 up to 4 etc.

Soly Pequencer (computerscare)
RGATE (Bogaudio)
Soly Pequencer (computerscare) steps through the channels of a polyphonic signal like a sequencer. Step advancement (forward only) through the clock signal.
Output is polyphonic. When providing a monophonic clock, all output channels carry the same values. When a polyphonic clock signal with different clock rates is provided, e.g. created with a polyphonic clock divider such as RGATE (Bogaudio), each output channel cycles through the channels at the respective speed.
