Sometimes I wonder if I buy so much NI stuff partly because they have such well produced product videos. Very possibly. Below is one of their latest Maschine promos/tutorials. I like it because Mark Kinchen (who I admittedly hadn't heard of until now), walks through his workflow and process. For him, remixing involves:
Mute all the instrument tracks
Play drums with the acapella track
Find a key that sounds good
Chop up acapella vocals
Create a new melody
I'm going to let this be my guide for Towers. By following this method, I'll inevitably stray much further away from the original than I did on the first three tracks. I'm going to give this a shot and hope that the limb I'm on doesn't crap out.
