Main reason I'd like Maschine output routed through Traktor is to be able to get headphone cue/solo for Maschine just like I can with track decks or sample decks and also to access Traktor filters, EQ and FX. For me the tightly integrated remix decks are a welcome compliment to Maschine's abilities. Maschine doesn't timestretch audio loops the same way. The F1 looks like it makes handling remix/sample decks easy and fun. Maschine excels as a groove sequencer/sampler/VST host. All handy creative tools. Now I could just wish for a dedicated 'Maschine deck' option.
Yes it kind of sucks we can't program the same functionality but on the other hand it looks like they made a nice controller.
