I don´t really know how to create them either but I found some nice samples to screw around with.

Some really high quality kicks 
I’ve put an example online for you to download. Keep in mind I just listened to the site dopefisch mentioned and tried to sort of quickly recreate it with native Renoise compressors, distortion, EQ and a little reverb. Hopefully it is what you mean? I’m not a hardstyle producer 
As i mention somewhere in forum before - my favourite free compressor for pumping fx is Arguru’s STARDUST page
Controls setup is very easy and intuitive.
BTW: very nice example you made, Rick ! 
hello, i ve been looking for a Good Hardstyle kick+ bass for LOOOONG time now, too.
the little i ve been able to know is that the bass in Hstyle start on the beat ( instead of halfbeat) and has a long attach.
so it s more like this:
c-4 1 00 | c-4 2 00 |
0-0 | 0-0 |
0-0 | 0-0 |
0-0 | 0-0 |
c-4 1 00 | c-4 2 00 |
i remember i sampled a VERY good bass from a technoboy track and i ve also used it in a gabba track of mine. i guess i ll be able to find it again.
it s kinda old but with some eq and compression everything will be fixed…

Sounds to me like you’re all discussing about one of the main themes in the wide field of making music. The Bass + BDrum “paste” is what makes the “beat” in the first place and the two instruments really have deep interaction that sounds totally different each time you change something.
If we’re trying to describe a dsp approach that’s fine… but there is no “trick” to get a “Good bass+bdrum line” as this is somehow like asking “how do I compose a catchy melody?” and that’s a bit too wide of a topic 
What I wanted to archieve was just to get fatter basses. The Example above sounds exactly what I was thinking about. Just a normal bassdrum and some kewl fx and this makes my day…
Uhm… I’m not sure what you mean by split but the way Renoise works is that if you want to use 2 channels with the same effect, you have to use a senddevice and point it to the channel where the effect is located. You can download my example and see what I did. If I’m doing it wrong please correct me. And keep in mind we were trying to achieve an effect that gives us that hardstyle like sound not mastering a track.
to make those really dirty overdrived drums i would recommend a waveshaper.
cyanide (google…) is a good one.
at first opening drag the right point to the upper right corner, then take the middle point and drag it to the left-upper corner. to get more distorted sound left-click on an empty space and drag this point to the left-upper corner too.
just a recommend. there are much more strange things you can do with it.

makes even a nedledrop sound like it got amped up and played on a 4x12inch speaker system!
KABOOM KABOOM!
mabe not, but it gives bottom, feel, and flow.
When using the Send channels in Renoise you can choose whether to send the original signal on through the DSP chain, and ultimately onto the Master channel, or to cut it off at that point, ultimately merging more than one track together for using effects on the whole lot (much like with real auxilleries, although a real desk has gain at the beggining and end of the chain.)
Like this you do process the whole sound, not just a split of the signal (unless you have chosen not to.)
There is a royalty free sample pack that can be download here…
http://physics.queensu.ca/~jdane/equinox_samples.zip
The technical term for what you are after appears to be “gated” of which you’ll find a number of “gated” kicks in this pack…
There is also 50 diffrent “gates” for kicks on the Vengeance Essential Clubsounds CD although it is a little pricey…
It can be found here…

You can also just cut off the gates of any kicks you find that have them and mix and match with other kicks…
I don’t quite know where your problem is making hardcore kickdrums but if this is too simple let me know.
The hardcore kickdrum is made by taking a normal 909 style kick and
distorting/overdriveing it. The more distortion the more sustain or “tail” the kick will have. You can get cool variations of this by connecting the kick to the following chain:
Kick - distortion - EQ - distortion.
Add more of each anywhere in the chain that you like but distorting the eq’d signal makes it sound different. In particular, add some midrange on the eq and experiement with the settings. I’d create wild hardcore kicks by long chains of dist and eq machines. If you want some “boom” to the kick run it through a reverb unit, but this works best on kicks with a fast decay (low distortion amount).
Here’s some of my hardcore tracks I produced on Buzz, are you looking for kicks like that?

I look forward to cranking out some obscene electonic distorted mayhem on Renoise.
Exactly that is it
If you send me a renoise signal-chain with how you do that… would be great
info at trancefish dot de
Well, I made all that stuff on buzz tracker but the method is the same. I played around with a 909 sample and the default renoise eqs and distortions and got a little demosong for you. Check your email. If anyone else is interested let me know.
Thank you for that distortion - eq trick for creating gabba kicks its is exactly what i have been trying to create.
Greenchild, I tried to send you the demosong but the email bounced back. Let me know where u want it sent and I’ll get it to you.
The only thing i have read about raising the dimension of your basses is by eq-ing them around the ~100Hz band (103 or 106 hz) (at least to get them warmer).
That one didn’t work either greenchild.
we need a propellerhead reason kind of “scream distortion unit” effect for renoise … youll be amazed of what you can squeeze out of that baby 
the best for bassdrums imho
Get some decent drum samples,then add a little distortion to the kick,and any lofi fx will also be good,also try a little distortion on the snare,this will make your beats have more power,and of course use a decent compressor,*
