Nice browsing of all NI plugs (I own Komplete as well) and its waaay better for me to load Kontakt libraries through Maschine as opposed to kontakt itself. Best software step sequencer that I've used and it obviously integrates very nicely with the hardware controller Pretty much use Maschine as my goto source for drums and percussion (good hip hop + electronic sounds) Maschine has some great built in sounds (and some nice expansion packs).
I use a Maschine Mikro Mk2 alongside S1v2 as my primary DAW and I really like it. I would imagine anything you might create using Maschine and its own software would be able to be rendered out and dragged into Studio One obviously for the more familiar linear work flow a linear based sequencer provides. I am sure you could access the Maschine sounds using Studio One but then it turns into more of a sound generator then perhaps and Studio One may not integrate as well with it as it does with its own software.
But it comes with its own fully deeply integrated DAW so I would be much more inclined actually to not use something like Studio One at all but use Maschine on its own with its own software running on your computer. Jemusic wroteI am quite interested in Maschine Mk 2 myself.
