Hi

I'm trying to make a remake of this remix by David Guetta: https://youtu.be/zfTs0_9121Q?t=67

Currently I'm having troubles making the sound of the bass. I've figured out it is some kind of FM bass and I've got pretty close, but not there yet. Mine is lacking the power and jelly-ish tech sound, you know. It seems like there is some kind of short resonance modulation or something.
So I'm wondering if someone knows how to make a bass sound this wide and full or at least has some suggestions?

I'm using Massive for this one.

I had a quick listen and I think it's just a sub sine.
The rest of the "bass" comes from the piano. I could be wrong but try making te chords and add a sin-sub and see if it sounds right.

If not I'll check back tomorrow

Heading to bed now

I think this might be what you're looking for

A free FM synth that also has filters: Oxe FM (skinnable)

A free Yamaha DX7 emulation: Dexed

FM and AM behave sort of similar in the way that both are generating SUM and DIFFERENCE frequencies: sidebands. The higher the modulation amount the more partials/sidebands. In FM DIFFERENCE frequencies that go into the "negative", "bounce back" with their phase inverted, changing with the amplitudes of partials that are already there as a "sum".

Anyway...

Since you get SUM and DIFFERENCE, at a ratio 1:2, you will get ODD partials only. So while turning the amount of modulation up it will go from SINE via (sort of ) TRIANGLE to (sort of) SQUARE. But beyond that it doesn't really sound "ODD" anymore due to ever more partials/sidebands and "back bouncing" "negative" "difference" partials interacting with "positive" "sum" partials.

Another FM thing: feedback. Feeds back an output and feeds it back into a (modulation) input. Extreme feedback results in chaos (noise). In moderate amounts will make a spectrum more complex, since more just a sine (single frequency) is fede back in, generating more frequencies/sideband etc.

Hmmm...the effect of ratio and amount and feedback in FM must be hard to grasp from just reading these words....

The above summarized....and a quick actual try with Dexed

For this sort of bass: it's nearly a pure sine. Maybe just a 2 operator stack with feedback (In Dexed or a Yamaha DX7, e.g. algorithm 2) at ratio 1 (carrier) : 2 (modulator). That will generate odd partials only. So it wil be a sort of Lowpass filtered Triangle. You could also try some feedback. But you lack a bit of further spectral control.

Maybe just move on to a 3 operator stack (since that's also a 2 operator stack when the top operator (6) is at level 0).

So, let's just move on and try a 3 operator stack with feedback at ratio's 1:2:1 (algorithms 3 or even better 4, operators 4, 5, 6) to get some more control over the modulators (5 and 6) combined spectrum. Try level 1=99, 2=45, 3=63, feedback=2.

Fiddle with operator levels and feedback amount. Maybe change the ratio of 6 (or even 5). At ratio 1:2:2 you get a more odd partial vibe (think a sort of 50Hz/60Hz alternating current square sound). At 1:2:3 you get a bit more saw/overdrive feel.

No envelopes are needed here (I guess).

The bass in the (superb) track below is more of a pure sine. Brings back many memories of the great and innovative electronic music in the early nineties...
