SA C4, Synth and Filter experts... Assistance please? 🙏

Hey all!

 

My band has recently started doing a techno version of Eminem's "Without me" (youtube link to the song we've based it off is below) and there's a very specific bass synth "wub" type sound that I'm struggling to nail... I'm convinced it's hiding in the C4 somewhere, and I'm close - but I think I'm struggling to get the filter right!

 

Any suggestions would be much appreciated!

 

The "wub" begins at around 42 seconds in

Sounds like there may be a fifth interval in there (quietly). Doesn’t sound like anything too complex in terms of oscillators, though if the pulse is less than 50% duty cycle C4 can’t do it (though can be fudged via FM). Cutoff seems relatively static. Might be better to get the swell from the amp envelope instead. I’d guess it’s sidechained too so might be worth experimenting syncing the LFO to achieve the ducking.

Put a donk on it!

The 5th interval made sense... the rest was all swaheelee though! 😂 what do you mean by amp envelope?

Amp envelope - amplifier envelope, loudness envelope. On C4 that is whatever envelope you assign to the input of the voice(s).

Ah! I've actually got it set to swell already... it just doesn't have the same sort of peak as what I'm trying to achieve, and the cut off doesn't seem as sharp.

Envelope options on C4 are pretty limited, despite the long list. Still wish it had ADSR.
