"Gastric" Drum and Bass synth sounds?

[sensorium]

I'm not a D&B producer, but I do like the sounds used in the style. Maybe because I've never personally figured out how to recreate them? How are sounds like this achieved?

Breakbeat "gastric" bass sounds are the holy grail for me and are quite hard to make, but many producers like to use Reaktor to achieve it, loading bass synth samples into a granular synth and twisting it to h**l and then cutting up the short snippets and arrangeing them in a software sequencer is my preferred method. But for things like the classic "reese" bass you can get stuff quite similar from the SH-101 with LFO Pulse Width Modulation and Sub-Osc.

Oh and LPF cutoff modulation is a must for D+B

Edit: S@#T just saw your gearlist, its huge , just realised you have an OSCar, get that old beast going and the bass will be shakin' the walls for sure, definately one of the best bass synths for D+B IMO.

I am not sure if its exactly what you are looking for but at about 1:46 for a couple of seconds on this video

It is just NI Massive, with a slightly tweaked version of one of the bass sounds. that sound was already pretty well set up once I "learned" the 8 metacontrols to that little controller it wasnt hard to find the ones to twiddle
I think it is better to modulate it yourself, (or record an automation lane) anything that tries to do it for you does not seem to sound right.

The Virus Ti also has some suitable sounds as well.

Hmm, I've been wondering about this also. I've just been looking for as many different ways to make bass sounds as I can. This is one I haven't nailed yet. I wonder if anyone will come in and describe specifically how they make that sound. Hmm. . .

BIG UP THE GASTRIC MASSIVE! BO! BO! SELECTA!

It sounds like two different bass sounds, run through different filters.

yeah.. layering and LFOs will get you to the basis of a lot of these sounds. LFOs that can run into audible frequencies probably would be helpful

I think the key in these badass dnb bass sounds is layering several bass sounds with fast modulation, compressing, resampling and then re-modulating.
Usually a sub bass sound is layered with a complex modulated reece bass sound in order to achieve a solid booming and an organic/growling sound.
About the reece part , it is good to start with a small detuning of the OSCs to achieve a fast osc beating, then route lfo to PW , lfo to ring modulation, lfo to FM amount or anything that can provide that motion and dirt to the sound. Usually portamento is applied but not in this specific sound.
The characteristic tone is achieved by heavy filtering, not only LPF but BPF & BSF modulated by fast complex envelopes or free envelope drawing in soft sequencers.
Compressing / Resampling is very important to create this "punchyness" that most hardware synthesizers fail to provide.
Personally I find Access Virus and Yamaha AN1x very good to emulate these bass sounds. I really dig the the Free EG and Feedback function of the AN1x

there is the first sound, the most 'gastric' sounding which sounds like a very filtered saw wave with some LFO modulating the pitch. The fact that the LFO is modulating the pitch, makes the actual pitch less definable but fills a lot more motion in the low end. I'd call this sound ' day after eating bad clams'.

The second one that comes in a few bars later is about an octave or two higher with a lot of filter mod, probably played real time, with a 1 or two octave lower sine wave.
This sound should be called 'day after eating extra spicy curry'.
