First of all, of course there are no rules, for any principle that anyone puts down, someone else is going to make something unique by breaking it.
That being said, generally speaking I’d disagree with this - if you’re going really deep into hiphop beat construction, it’s more than swing and templates. It’s especially important in hiphop because the beat is so central and so repetitive, if you don’t have a really compelling 8 beat loop, you don’t have anything. With electronica, it’s a different story obviously… and I love a lot of electribe/renoise gurus who’s stuff is entirely on the grid.
First of all, the way in which notes are nudged becomes very personal reflection of the playing style. For instance, someone self-taught may have a particular way of lagging/chasing the beat. Timing (and imperfections in timing) is a direct reflection of the way one has played and performed over the years and turning up the swing parameter, randomly adding offsets to a template, or using someone else’s groove templates is generally not going to capture a personal style in the same way. Of course, once you know your own style, you can do your best to capture it by other means (manually adjusting the template to mimic how you play), but I’m willing to bet that most people who use swing/templates don’t use it in this way.
The list of artists is endless, but personally I like RZA and Timbaland. With RZA he’s not formally trained and you can hear that - but the apparent sloppiness makes the music much more personal and genuine. With timbaland, he has a very unique sense of groove - anyone can mimic the way he distorts beats, but no one can time beats the way he does (I realize he’s unpopular in tracking circles cause of the plagiarism thing, but that’s a seperate issue). Keep in mind just because something sounds like a drum machine doesn’t mean it was on the grid. Often 808s and whatever are sampled and re-performed through a sampler. Even in a lot of the early hiphop, you’ve got people like Mantronik and Public Enemy doing tape edits or using primitive samplers to give the music some groove. In fact, in a lot of the early PE material, the full backing track was one live ensemble performance.
Also, micro-timing can blend into sound design. For example, offsetting (in ms) the kick, snare, and clap in different ways can thicken the sound of a hit in different ways, even more so if the sounds are being squashed together into a saturator or compressor.
