Oscillator Sync/Fm/Ring Mod: I Don’t Get It

Hey all,

So I’ve been progressing well through Syntorial and I just finished the LFO Trigger/Poly lesson.

My biggest issue is hearing the difference in the heavier/grindier sounds.

Specifically, I feel like there are so many ways to make grindy/distorted/metallic sounds. Main methods include Oscillator Sync, FM, Ring Mod, pulse wave with lfo modulating the wave, and pulse wave with distortion/band pass filter/resonance.

It’s getting harder and harder for me to hear the difference in what is being used, particular between Sync, FM, and Ring Mod.

Any tips for how to hear the differences between at least these three? i find myself just trying each of them out but then there’s all the various semitones you can pick and, since it all sounds crazy to some extent and not like normal intervals, i just cycle through them to find the matching pitch (which is extremely tedious, especially if i was barking up the wrong tree in the first place).

curious for any thoughts more broadly. i think part of the issue is i have no idea what sync, fm, and ring mod are actually doing (ie how it actually works). i know fm and ring are supposed to be more “bell like” but you can make bell-like tones in a bunch of ways (eg a transposed pulse and triangle wave).

anyway, curious for your thoughts!
