Kore is far more than that, but I guess you could call it that. The touch sensitive knobs use track automation at 500 steps VS 128 in MIDI, there's simple MIDI file players, step sequencers and arps in Kore already, basically everything is in place for Kore to get A full on Sequencer IMO. Only thing missing is an actual full on audio/MIDI arrangement type environment. Just thinking out loud here (as if that's unusual), but it's also very possible that NI release a Record style sequencer where Kore and Maschine are add ons that give proprietary functionality. This actually would make perfect sense, in that between Kore, Maschine and Reactor you would have everything except straight audio tracks, and if NI did it themselves they could add the hooks for Reactor and Kore/Maschine to integrate at some ridiculous level.
You're aware that the core of Ableton engineers used to work for NI right? well when I first joined here, employees posting in threads would sometimes remark about how they valued stability over introducing products to early like other german developers, and it was obvious they were talking about NI, Reactor and Kontakt had some stability issues at that point.
(This is of course ironic as hell now, years later when NI kit is essentially stable and 8 has had so many issues)
There's certainly a difference of approach when it comes to product development, just look at the VAST difference between Sampler and Kontakt. In many ways I prefer NI's approach, (seriously, I will never get why anybody would prefer Sampler?), though Ableton mostly aren't bridge burning path cutters, and I mean that in a good way. Guitar Rig 4 lost the ability to save a Preset Attribute (bank) list of presets with your DAW, so if you change presets it jumps to the folder on your HD containing every single freaking preset numbers them in some odd way and then doesn't work, until you select the bank sitting in GR4's browser.... bleh, sorry about the rant, but it's frustrating as fuck, and I'm sure it's due to NI attempting to get all their plugs to adopt the Kore browser format.
