Reply to How to sample audio from my Mac (Youtube, iTunes, etc) into Maschine

This has probably been solved many times, but i don't know how to do it. I just want to be able to record/sample audio from my MacBook into Maschine. So YouTube, iTunes, and so on..

I have a Lexicon Alpha USB soundcard going to my monitors, (i have a NI Audio 10 also if its needed). And i downloaded the soundflower app a while ago, but dont know my way around it.

So, how would i successfully be able to sample any audio from my mac into Maschine?

Thankyou
