I'm trying to recreate this bass sound from Stone Cold. - The Caracal Project that starts 5 seconds in.

It seems like it should be easy given how simple the sound is, but I just can't seem to get it right. Looking at the waveforms for the right and left channel they appear to be subtly different, which makes sense as that's probably how it's achieving such a clean/wide sound. Both channels look like they start as a squared-out sine wave (probably just a touch of soft clip waveshaping?) and then the two diverge and introduce some additional harmonic content, but each is totally different.

I'm thinking this is just two hard-panned oscillators, each with a bit of FM and some waveshaping.

When I try that I seem to be landing with either too many harmonics, or not enough. Also not sure what synth allows for two totally independent oscillators that can be hard-panned, where both could be treated with FM independently.

So like... is this two separate hard-panned synths?

Just feels like I'm massively overcomplicating things.

Help?
