Hey, I was in the same boat as you. Still a beginner but here is my take.
Quantizer is best used (IMO) with random CV or a LFO and then attenuate it for range.
For example, Change PAM’s WAVE from a GATE to RANDOM. Since its a sample and hold, it will play a steady CV per beat. You then feed it through a quantizer so it will actually play in tune/scale. Now you can change the LEVEL in PAM’s settings so it doesn’t jump to high and low.
You can also feed an LFO and attenuate it through a Quantizer for the same effect, but more arpeggiated.
The weird thing about modular sequencers is that many are not quantized by themselves. So you do in a sense have to feed it through a quantizer. which i find redundant. I like using a quantizer for weirder signals, rather than ‘tuning’ a sequencer.
My suggestion would be to get something like an “Ornament & Crime” module. It fit my bill, and its a really good way to start sequencing multiple modules in your kit.
Sorry if none of it made any sense.
