drum programming

I’m a total newbie and I’m wondering about drum programming. I am using Addictive Drums 2 for my drum sounds in Cubase 6.5.

This tutorial shows us how to set up separate channels in the Cubase mixer so we can manipualate the tracks with the effects in Cubase AND record audio (https://www.youtube.com/watch?v=Uw4Z5EVXtIc) . Why wouldn’t I want to just set up separate channels as in this tutorial (https://www.youtube.com/watch?v=dy9ovAd4rUA), recored two channel stereo MIDI and just control volume and effects in the Addicitve Drums mixer instead if I’m satisfied with the effects in their program?

Are you asking what the advantage of recording the output from the instrument is vs. just playing the instrument via MIDI every time? The main advantage I can think of is to “freeze” the instrument, which means rendering the output of the instrument as an audio track, the playback of which is generally much more CPU-efficient than playing the instrument with MIDI every time.
