It’s not a NI thing, it’s more like a computer audio thing.
With a single Elektron box, or even with a small hardware setup going through a single mixer, the audio routing and gain staging is really very simple and you’ll end up setting levels roughly optimal almost without having to think about it.
Analogue mixers are also forgiving; the distortion you get when you set levels a bit too high is mostly pleasant and introducing a bit of hiss from adding too much gain at the pre-amps often just adds a bit of “warmth”.
With computer audio, you quickly end up with a much more complex setup that rivals the routing in a multi-million dollar studio. Especially in a modular environment like a DAW or Maschine, you’re effectively doing gain staging at the inputs and outputs of every plugin or processing step in the signal chain.
Digital audio is also much more transparent; you don’t get nice saturation when you push levels and you don’t get hissy warmth when you add too much gain.
As mentioned above, reading up on mixing and experimenting with this stuff really does help.
