There is a limitation to @almostEric’s PROBABLY quantizer. Rather it’s a feature but doesn’t work the way I want it to.
Namely you need a Pitch AND a Trigger input. Where other quantizers operate continuously, the PROBABLY quantizers introduce a Spread input, which means that given a particular voltage, it selects a quantized pitch randomly from a range around that voltage. He uses the trigger to sample the input and run it through the complicated transform that introducing Spread (and all Spread’s controlling parameter). This wouldn’t work with a continuous input/output, or at least it wouldn’t work the way PROBABLY quantizers work.
The limitation? PROBABLY will quantize polyphonically but the Trigger input is monophonic.
My solution - as in this Strip preset and the image below - is to send the sequencer’s clock input into the PROBABLY trigger, so each note input is sampled on every clock tick. Then I split the polyphonic Gate from the sequencer and the polyphonic Quantized Pitch output from PROBABLY.
I use the split monophonic gates to sample monophonic pitch CVs, then use a VCV Merge to recombine the monophonic pitches back into a polyphonic Pitch output to pass on to Oscillators.
The effect is what I wished the PROBABLY quanitzers did in the first place: Use a polyphonic trigger input for sampling the incoming polyphonic pitch CVs.
So is there an easier way to do this? As far as I can work out there’s only one S&H module, the Bark S&H/T&H but it didn’t work the way I wanted it to. I wasn’t sure what it was doing actually.
