This may be a dead thread, but I still want to post my thoughts
Just before I start, I'm just going to warn you, I'm just posting a quick kind of tutorial on a technique I literally just thought of while reading through this thread, so I haven't personally tried it yet, but I probably will right after I write it out on here.
So...if you want to try and make a kick similar to porter's, try this out.
1- Get the kick from one of Porter's track that you want to try and replicate or use to make a similar kick of your own. Link it to your mixer and apply a lowpass filter.
2 - Find a kick with a similar low end, and link it to the mixer applying the exact same lowpass filter you applied to Porters kick.
<-----> For this part I'm not sure how you would do this in other DAW's, but I use FL Studio, so if you do to then you can just use these exact steps <----->
3 - If the first kick you used doesn't sound close enough, go through your sample pack and find the next similar kick, right click it and click on "Send to selected or focussed on channel" or whatever that says. This will send your new, different sample, to the same channel so that the lowpass filter will still be applied.
Continue doing this until you find a kick you're satisfied with.
Once you have your low end kick that you're satisfied with, continue the process by cutting the low end of Porter's kick, and the low end of some new samples, so that there is only the higher, more punchier, parts of the kick. You may want to apply a lowpass filter as well at about 8000hz, because a lot of producers like to layer in a hat to give the kick a little more "crispy-ness", and by cutting those really high frequencies, you'll be able to take out some of the hat, making it easier to compare the higher ends of just the two kicks.
This technique will cut both your sample, and Porters kick, at the exact same frequencies, allowing you to hear only those frequencies, which makes it much easier to compare, and choose a kick that's similar.
You can use this for 2 different kicks, 3, 4, however many you want, but the more you use, the more frequency cutting in different areas you will have to do.
Once all your samples are picked, then it's time to start layering each together. All I can say about layering kicks is that you're going to have to do some lowpass and highpass filters so that the frequencies of both kicks aren't clashing together, and making the sound "muddy". From my small amount of experience with layering kicks, I found that the area that will cause the most problems is usually the bass/sub of the kicks, so try to dedicate one kick to that area, and layer the rest into it by cutting out those lower ends.
Play it by ear and try not to overcomplicate things, not only with kicks, but with everything, especially with making basses. There are a lot of bass sounds out there like Porter's, that are so crisp and clean, yet dirty, and if you find yourself trying to make a similar bass, just don't over complicate it. Too much compression, EQ, distortion, or any other effect can turn something with potential into complete shit. Instead, try layering. It will make the sound so much fuller, and so much better. I'm no pro at it, but I've definitely started learning how much more it helps to layer rather than over process a sound.
Best of luck to everyone, and I hope this helps at least one person!
i did the same thing one for that tune, shove some hihat snippets and better kick transients on it and then compress / transient shape and then voila
