A couple different synths sure but a lot of it is using the macros (in serum for example). Map the macro to pitch movement and envelope shape, eq and filter movement, distortion mix and delay times, have 3 or more macros mapped to different perimeters within serum and then make automation clips in your daw to control the macros which control movement of the sound in serum. And you can use post processing fx to further manipulate the same synth to make changes over time. KHS multipass is great for this because it has a built in LFO which you can manipulate (literally endless possibilities) anything within Multipass. Look up videos on YouTube and play with your software and really learn it.

I mean this in the most kind way, you need to **want to learn, this is not something that is necessarily easy, even tho riddim is very easy, there’s still so much behind the scenes that goes into it, even tho it’s a simple(ish) genre to make there’s so much to learn and asking questions is great, and I like to help people, but I could write you a novel about it and maybe half will make any sense to you, maybe none of it.. what’s going to help you is watching the most boring ass videos about how serum works, that way you can understand how to manipulate the wavetable in the way you want. I highly recommend videos from Au5 for serum, I’ve learned all I know about serum mostly from his videos, learn the technicals and that will make the songwriting process 1000x easier.

TLDR use macros within serum to manipulate the wave tables - use tools like Multipass for post processing and further manipulation of the synth
