Just wrote a shit load here and then my browser went back when I hit backspace.
Anyway, here goes...
I've been trying to re create that basic channel sound myself for many years and to be honest i've not heard many people pull it off, even excellent producers with access to expensive kit.
Take the maurizio style kick for example, try using a 909 kick, put it through a low pass filter, use a nice compressor to fatten it with an attack of about 30 ms, then add a smidge (and i mean just a smidge) of distortion just to warm it up, then send it to a return with some nice cavernous reverb on for that dark rumbling sound, play with the reverb eq and dampening to take out any unwanted frequencies at the reverb end.
For that roll on roll off bass with a different style of kick, use a similar style of kick to above but without the reverb and put it through something like RBass (Waves Renaissance) or if you don't have waves then try Lowender plug in that is either free or cheap. For the bass use either a bass guitar or just a synth, put it through a low pass filter, then put it through a compressor to fatten it up, then again put it through RBass or Lowender and finally eq both the kick and bass to make them sit nice together.
Also if you listen to a basic channel track there are so many subtle changes through the tracks, that is what makes them sound so amazing to me, there is nice modulation with the percussion that can be achieved by clever use of velocities on the drums or from mixing down live or even have an LFO controlling the volume or filter on the percussion, it all adds detail and keeps the listener interested even though the track is basically a dubby loop playing for about 10 mins.
Also try using snares and putting them through a spring reverb as a one hit and maybe do it again later in the track with some delay on it.
Audition loads of synth presets and find some nice crackly sounding ones, modulate the filter on the synth, maybe bang another filter or 2 after the synth, maybe a low pass and a high pass so you can change it throughout the track and also have about 5 or 6 returns with different delays in them with different settings so that you can send the synths and stuff through them throughout the track.
Just experiment and see what you come up with.
Also try using groove templates, just record a section of say M3 and trim it to exactly 4, 8, 16, 32, 64, 128 or whatever length it is you want to use, bigger the better so you can use larger sections and have more change in the groove. Then in logic make a groove template from the audio and then quantize your beats to the groove template you made and you will get the same groove in your track. It's a case of getting a nice swing rather than just having straight tight quantized beats but it's hard to get it just right with too little swing it sounds wooden and too straight, and with too much it starts to sound like a swing time jazz track. Using other people's grooves by making a template is easier and you can use tracks that are similar to what you are creating. That is the beauty of a proper 909 rather than all the plug in versions, the sounds are pretty much the same but the groove isn't and nothing compares to analog circuitry for giving some slight swing even without it turned on as it's just not as tight as a digital version that is more precise.
Looking forward to hearing what you come up with anyway, for me musical talent doesn't really come into it, your not writing a beethoven symphony, you don't need to be able to play an instrument, it's all about the noises you use, modulation and groove with this kind of music.
